When you first learned the facts about pregnancy — from a parent, perhaps, or a friend — you probably didn’t learn that up to one in three ends in a miscarriage.

What causes miscarriage? How is it treated? And why is appropriate health care for miscarriage under scrutiny — and in some parts of the US, getting harder to find?

What is miscarriage?

Many people who come to us for care are excited and hopeful about building their families. It’s devastating when a hoped-for pregnancy ends early.

Miscarriage is a catch-all term for a pregnancy loss before 20 weeks, counting from the first day of the last menstrual period. Miscarriage happens in as many as one in three pregnancies, although the risk gradually decreases as pregnancy progresses. By 20 weeks, it occurs in fewer than one in 100 pregnancies.

What causes miscarriage?

Usually, there is no obvious or single cause for miscarriage. Some factors raise risk, such as:

• Pregnancy at older ages. Chromosome abnormalities are a common cause of pregnancy loss. As people age, this risk rises.
• Autoimmune disorders. While many pregnant people with autoimmune disorders like lupus or Sjogren’s syndrome have successful pregnancies, their risk for pregnancy loss is higher.
• Certain illnesses. Diabetes or thyroid disease, if poorly controlled, can raise risk.
• Certain conditions in the uterus. Uterine fibroids, polyps, or malformations may contribute to miscarriage.
• Previous miscarriages. Having a miscarriage slightly increases risk for miscarriage in the next pregnancy. For instance, if a pregnant person’s risk of miscarriage is one in 10, it may increase to 1.5 in 10 after their first miscarriage, and four in 10 after having three miscarriages.
• Certain medicines. A developing pregnancy may be harmed by certain medicines. It’s safest to plan pregnancy and receive pre-pregnancy counseling if you have a chronic illness or condition.

How is miscarriage diagnosed?

Before ultrasounds in early pregnancy became widely available, many miscarriages were diagnosed based on symptoms like bleeding and cramping. Now, people may be diagnosed with a miscarriage or early pregnancy loss on a routine ultrasound before they notice any symptoms.

How is miscarriage treated?

Being able to choose the next step in treatment may help emotionally. When there are no complications and the miscarriage occurs during the first trimester (up to 13 weeks of pregnancy), the options are:

Take no action. Passing blood and pregnancy tissue often occurs at home naturally, without need for medications or a procedure. Within a week, 25% to 50% will pass pregnancy tissue; more than 80% of those who experience bleeding as a sign of miscarriage will pass the pregnancy tissue within two weeks.

What to know: This can be a safe option for some people, but not all. For example, heavy bleeding would not be safe for a person who has anemia (lower than normal red blood cell counts).

Take medication. The most effective option uses two medicines: mifepristone is taken first, followed by misoprostol. Using only misoprostol is a less effective option. The two-step combination is 90% successful in helping the body pass pregnancy tissue; taking misoprostol alone is 70% to 80% successful in doing so.

What to know: Bleeding and cramping typically start a few hours after taking misoprostol. If bleeding does not start, or there is pregnancy tissue still left in the uterus, a surgical procedure may be necessary: this happens in about one in 10 people using both medicines and one in four people who use only misoprostol.

Use a procedure. During dilation and curettage (D&C), the cervix is dilated (widened) so that instruments can be inserted into the uterus to remove the pregnancy tissue. This procedure is nearly 99% successful.

What to know: If someone is having life-threatening bleeding or has signs of infection, this is the safest option. This procedure is typically done in an operating room or surgery center. In some instances, it is offered in a doctor’s office.

If you have a miscarriage during the second trimester of pregnancy (after 13 weeks), discuss the safest and best plan with your doctor. Generally, second trimester miscarriages will require a procedure and cannot be managed at home.

Red flags: When to ask for help during a miscarriage

During the first 13 weeks of pregnancy: Contact your health care provider or go to the emergency department immediately if you experience

• heavy bleeding combined with dizziness, lightheadedness, or feeling faint
• fever above 100.4° F
• severe abdominal pain not relieved by over-the-counter pain medicine, such as acetaminophen (Tylenol) or ibuprofen (Motrin, Advil). Please note: ibuprofen is not recommended during pregnancy, but is safe to take if a miscarriage has been diagnosed.

After 13 weeks of pregnancy: Contact your health care provider or go to the emergency department immediately if you experience

• any symptoms listed above
• leakage of fluid (possibly your water may have broken)
• severe abdominal or back pain (similar to contractions).

How is care for miscarriages changing?

Unfortunately, political interference has had significant impact on safe, effective miscarriage care:

• Some states have banned a procedure used to treat second trimester miscarriage. Called dilation and evacuation (D&E), this removes pregnancy tissue through the cervix without making any incisions. A D&E can be lifesaving in instances when heavy bleeding or infection is complicating a miscarriage.
• Federal and state lawsuits, or laws banning or seeking to ban mifepristone for abortion care, directly limit access to a safe, effective drug approved for miscarriage care. This could affect miscarriage care nationwide.
• Many laws and lawsuits that interfere with miscarriage care offer an exception to save the life of a pregnant patient. However, miscarriage complications may develop unexpectedly and worsen quickly, making it hard to ensure that people will receive prompt care in life-threatening situations.
• States that ban or restrict abortion are less likely to have doctors trained to perform a full range of miscarriage care procedures. What’s more, clinicians in training, such as resident physicians and medical students, may never learn how to perform a potentially lifesaving procedure.

Ultimately, legislation or court rulings that ban or restrict abortion care will decrease the ability of doctors and nurses to provide the highest quality miscarriage care. We can help by asking our lawmakers not to pass laws that prevent people from being able to get reproductive health care, such as restricting medications and procedures for abortion and miscarriage care.

You’re in a doctor’s office with a clipboard and a pile of medical forms on your lap. For the umpteenth time, you must now jot down your medical history — conditions, ongoing symptoms, past procedures, current medications, and even the health of family members.

But how much information should you include? Which details are most important? And why are you slogging through paper forms when a digital version likely exists? Put down your pen for a moment and take a breath. We have some answers.

Do you actually need to fill out the forms again?

In many cases, you do need to fill out medical history forms. That can be true even if you already have a digital record on file, known as an electronic medical record (EMR) or electronic health record (EHR).

The reason for collecting new information could be due to a variety of reasons:

• The health care provider might want an update, since information like medications or new health problems can change over time, or you might have missing or inaccurate information in your record.
• Different specialists need to know about different aspects of your health.
• Your EMR at one provider’s office might not be accessible to others because practices don’t always have compatible computer software.
• Some practices don’t want to rely on records created by other practices. They may not trust that they’re accurate.

What if you don’t want to fill out the forms?

“You don’t have to,” says Dr. Robert Shmerling, a rheumatologist and senior faculty editor at Harvard Health Publishing. “But the response from the practice might be, ‘How can we provide the best care if you don't provide the information?’ And if you persist, you run the risk of marking yourself — unfairly, perhaps — as uncooperative.”

What are the most important details in your medical history?

The most important details of your medical history include

• chronic or new symptoms and conditions
• past surgeries
• family medical history
• insurance information
• current prescription and over-the counter medicines, supplements, vitamins, and any herbal remedies or complementary medicines you use
• medication allergies
• vaccination history
• any screening tests you’ve had, so they won’t be prescribed unnecessarily
• any metal implants you have, which could affect screenings.

If you don’t know all of the details, try to get them from a previous doctor or hospital you’ve visited.

“In some cases, not having the information could be a problem. For example, I need to know if my patients have had certain vaccines or if they have medication allergies,” says Dr. Suzanne Salamon, associate chief of gerontology at Harvard-affiliated Beth Israel Deaconess Medical Center.

Which information might be less important?

Sometimes, leaving out certain details might not matter, depending on the purpose of your health visit. For example, your eye doctor doesn’t need to know that you broke your wrist when you were 18, had the flu last year, or had three C-sections. But they should know which medicines and supplements you take, and whether you have certain health conditions such as diabetes or high blood pressure.

Not sure what to leave in or out of your history? Dr. Salamon suggests that you at least focus on the big stuff: chronic symptoms and conditions that need ongoing treatment, medications and supplements you’re taking, and your family medical history.

“If you can, bring a copy of your medical history to all new doctor appointments. It could be written or printed from your patient portal or kept handy on a digital health app. That way, you’ll have it handy if you need to fill out medical forms or if the physician asks you questions about your medical history during an appointment,” Dr. Salamon advises.

How secure is the information you’re providing?

We trust health care professionals with our lives and our most private information, including our social security numbers (SSNs). SSNs are used to double-check your identity to avoid medical errors, and to make sure your insurance information is accurate and practices get paid.

Is it really safe to hand over the information? It’s supposed to be. A federal law called the Health Insurance Portability and Accountability Act (HIPAA) protects your health information with very strict rules about who can access it and how it can be shared.

“Medical practices take this very seriously,” Dr. Shmerling says. “They have lots of safeguards around personal health information, and routinely warn medical staff about not looking at or sharing information inappropriately — with the threat of being fired immediately if they do. Electronic health records usually track those who look at our information, so it's often not hard to enforce this.”

But no hospital or other entity can guarantee that your information is protected. That’s true of all information, especially with the constant threat of cyberattacks.

“So if you feel strongly about it, you can try saying that you’d rather not provide certain information and ask whether the practice can explain why it’s necessary,” Dr. Shmerling says. “It takes a certain amount of trust in the system that personal health information will be kept private, even though that may feel like taking a leap of faith.”

When a prostate-specific antigen (PSA) blood test produces an abnormal result, the next step is usually a prostate biopsy. A biopsy can confirm or rule out a cancer diagnosis, but it also has certain drawbacks. Prostate biopsies are invasive procedures with potential side effects, and they often detect low-grade, slow-growing tumors that may not need immediate treatment — or any treatment at all.

Researchers are exploring various strategies for avoiding unnecessary biopsies. Specialized magnetic resonance imaging (MRI) scans, for instance, can be useful for predicting if a man’s tumor is likely to spread. A blood test called the Prostate Health Index (PHI) measures various forms of PSA, and can help doctors determine if a biopsy is needed.

In April, researchers at the University of Michigan published results with a test that screens for prostate cancer in urine samples. Called the MyProstateScore 2.0 (MPS2) test, it looks for 18 different genes associated with high-grade tumors. “If you’re negative on this test, it’s almost certain that you don’t have aggressive prostate cancer,” said Dr. Arul Chinnaiyan, a professor of pathology and urology at the University, in a press release.

Gathering data and further testing

To create the test, Dr. Chinnaiyan and his colleagues first turned to publicly-available databases containing over 58,000 prostate cancer-associated genes. From that initial pool, they narrowed down to 54 genes that are uniquely overexpressed in cancers classified as Grade Group 2 (GG2) or higher. The Grade Group system ranks prostate cancers from GG1 (the least dangerous) to GG5 (the most dangerous).

The team tested those 54 genes against archived urine samples from 761 men with elevated PSA who were scheduled for biopsy. This effort yielded 18 genes that consistently correlated with high-grade cancer in the biopsy specimens. These genes now make up MPS2.

Then the team validated the test by performing MPS2 testing on over 800 archived urine samples collected by a national prostate cancer research consortium. Other researchers affiliated with that consortium assessed the new urine test’s results against patient records.

Interpreting the results

Study findings showed that MPS2 correctly identified 95% of the GG2 prostate cancers and 99% of cancers that were GG3 or higher. Test accuracy was further improved by incorporating estimates of the prostate’s size (or volume, as it’s also called).

According to the team’s calculations, use of the MPS2 would have reduced unnecessary biopsies by 37%. If volume was included in the measure, then 41% of biopsies would have been avoided. By comparison, just 26% of biopsies would have been avoided with the PHI.

Dr. Chinnaiyan and his co-authors emphasize that ruling out high-grade cancer with a urine test offers some advantages over MRI. The specialized multi-parametric MRI scans needed to assess high-grade cancer in men with elevated PSA aren’t always available in community settings, for instance. Moreover, the interpretation of mpMRI results can vary from one radiologist to another. Importantly, the MPS2 can be updated over time as new prostate-cancer genes are identified.

Commentary

Dr. Boris Gershman, a urologist at Harvard-affiliated Beth Israel Deaconess Medical Center in Boston, and a member of the advisory and editorial board for the Harvard Medical School Guide to Prostate Diseases, described the new study results as promising. “It does appear that the performance of the 18-gene urine test is better than PSA alone,” he says.

But Dr. Gershman adds that it will be important to consider how such a test will fit into the current two-stage approach for PSA screening, which entails prostate MRI when the PSA is abnormal. Where MRI delivers a yes/no result (meaning lesions that look suspicious for cancer are either present or not), the MPS2 provides numerical risk estimates ranging between 0% and 100%. “The challenge with clinical implementation of a continuous risk score is where to draw the line for biopsy,” Dr. Gershman says.

“This research is very encouraging, since many men in rural areas may not have access to prostate MRI machines or the added sophistication that is needed in interpreting these MRI scans,” says Dr. Marc Garnick, the Gorman Brothers Professor of Medicine at Harvard Medical School and Beth Israel Deaconess Medical Center. “A widely available urine test may eventually help provide more precision in determining who should undergo a prostate biopsy, and may also help to assess the probability that a cancer is clinically significant and in need of treatment.”

By the time boys are 8 or 10, they’re steeped in Marvel action heroes with bulging, oversized muscles and rock-hard abs. By adolescence, they’re deluged with social media streams of bulked-up male bodies.

The underlying messages about power and worth prompt many boys to worry and wonder about how to measure up. Sometimes, negative thoughts and concerns even interfere with daily life, a mental health issue known body dysmorphic disorder, or body dysmorphia. The most common form of this in boys is muscle dysmorphia.

What is muscle dysmorphia?

Muscle dysmorphia is marked by preoccupation with a muscular and lean physique. While the more extreme behaviors that define this disorder appear only in a small percentage of boys and young men, it may color the mindset of many more.

Nearly a quarter of boys and young men engage in some type of muscle-building behaviors. “About 60% of young boys in the United States mention changing their diet to become more muscular,” says Dr. Gabriela Vargas, director of the Young Men’s Health website at Boston Children’s Hospital. “While that may not meet the diagnostic criteria of muscle dysmorphia disorder, it’s impacting a lot of young men.”

“There’s a social norm that equates muscularity with masculinity,” Dr. Vargas adds. “Even Halloween costumes for 4- and 5-year-old boys now have padding for six-pack abs. There’s constant messaging that this is what their bodies should look like.”

Does body dysmorphic disorder differ in boys and girls?

Long believed to be the domain of girls, body dysmorphia can take the form of eating disorders such as anorexia or bulimia. Technically, muscle dysmorphia is not an eating disorder. But it is far more pervasive in males — and insidious.

“The common notion is that body dysmorphia just affects girls and isn’t a male issue,” Dr. Vargas says. “Because of that, these unhealthy behaviors in boys often go overlooked.”

What are the signs of body dysmorphia in boys?

Parents may have a tough time discerning whether their son is merely being a teen or veering into dangerous territory. Dr. Vargas advises parents to look for these red flags:

• Marked change in physical routines, such as going from working out once a day to spending hours working out every day.
• Following regimented workouts or meals, including limiting the foods they’re eating or concentrating heavily on high-protein options.
• Disrupting normal activities, such as spending time with friends, to work out instead.
• Obsessively taking photos of their muscles or abdomen to track “improvement.”
• Weighing himself multiple times a day.
• Dressing to highlight a more muscular physique, or wearing baggier clothes to hide their physique because they don’t think it’s good enough.

“Nearly everyone has been on a diet,” Dr. Vargas says. “The difference with this is persistence — they don’t just try it for a week and then decide it’s not for them. These boys are doing this for weeks to months, and they’re not flexible in changing their behaviors.”

What are the health dangers of muscle dysmorphia in boys?

Extreme behaviors can pose physical and mental health risks.

For example, unregulated protein powders and supplements boys turn to in hopes of quickly bulking up muscles may be adulterated with stimulants or even anabolic steroids. “With that comes an increased risk of stroke, heart palpitations, high blood pressure, and liver injury,” notes Dr. Vargas.

Some boys also attempt to gain muscle through a “bulk and cut” regimen, with periods of rapid weight gain followed by periods of extreme calorie limitation. This can affect long-term muscle and bone development and lead to irregular heartbeat and lower testosterone levels.

“Even in a best-case scenario, eating too much protein can lead to a lot of intestinal distress, such as diarrhea, or to kidney injury, since our kidneys are not meant to filter out excessive amounts of protein,” Dr. Vargas says.

The psychological fallout can also be dramatic. Depression and suicidal thoughts are more common in people who are malnourished, which may occur when boys drastically cut calories or neglect entire food groups. Additionally, as they try to achieve unrealistic ideals, they may constantly feel like they’re not good enough.

How can parents encourage a healthy body image in boys?

These tips can help:

• Gather for family meals. Schedules can be tricky. Yet considerable research shows physical and mental health benefits flow from sitting down together for meals, including a greater likelihood of children being an appropriate weight for their body type.
• Don’t comment on body shape or size. “It’s a lot easier said than done, but this means your own body, your child’s, or others in the community,” says Dr. Vargas.
• Frame nutrition and exercise as meaningful for health. When you talk with your son about what you eat or your exercise routine, don’t tie hoped-for results to body shape or size.
• Communicate openly. “If your son says he wants to exercise more or increase his protein intake, ask why — for his overall health, or a specific body ideal?”
• Don’t buy protein supplements. It’s harder for boys to obtain them when parents won’t allow them in the house. “One alternative is to talk with your son’s primary care doctor or a dietitian, who can be a great resource on how to get protein through regular foods,” Dr. Vargas says.

If the eyes are the windows to the soul, then consider the tongue a sort of check-engine light for the body. The tongue’s appearance gives doctors an idea about certain aspects of your health, and its color is an important clue.

What should your tongue look like?

The tongue should have a rounded, symmetrical shape. It’s generally light pink, though it may have a little purple or brown pigmentation in African, Asian, and Mediterranean populations. It can also have a hint of white coating.

“The coating comes from a tough protein called keratin, which helps keep your tongue from being scratched when you eat,” says Dr. Tien Jiang, a prosthodontist in the Department of Oral Health Policy and Epidemiology at the Harvard School of Dental Medicine.

Up close, you might be able to see that your tongue is covered in tiny bumps (papillae) that serve several purposes:

• They sense temperature and touch.
• They contain taste buds that enable you to detect if food is sweet, salty, sour, bitter, or savory.
• They create friction to help you form a little ball of food (bolus) that you can swallow.

Can diet affect tongue color?

Yes. Sometimes diet may be partly to blame for a shift away from your usual tongue tone. That’s because the papillae can absorb the colors and residues of foods and drinks you consume. For example, that blue popsicle or candy you ate as a kid probably turned your tongue an exciting shade of azure. Coffee, tea, and many types of foods, such as curried dishes with lots of yellow turmeric, can also leave their marks.

Discoloration is usually just temporary, however. Drinking plenty of water and maintaining good oral hygiene will wash away food and dyes that cling to the tongue.

A dark or bright tongue, white patches, and other causes for concern

Some tongue colors and appearances are signs of health issues. Check with your doctor if you notice any of the following:

• A brown or black tongue signals a condition called “black hairy tongue.” This occurs when papillae get too long. These tiny bumps don’t usually get much chance to grow because they are shed regularly with all the activity in your mouth. If they do grow, they can trap bacteria and a mix of food colors, leading to the brown or black tinge. Risk factors include taking antibiotics or antihistamines, smoking, dry mouth, drinking excessive amounts of coffee or black tea, or poor oral hygiene.
• Thick white patches or white sores on the tongue probably mean you have an overgrowth of yeast in the mouth (thrush). Thrush can be triggered by conditions such as diabetes or HIV, side effects of antibiotics or cancer treatment, wearing dentures, smoking, dry mouth, or using steroid inhalers. In rare cases, white patches or sores are symptoms of oral cancer.
• If your tongue has painful red or yellow sores, you might be dealing with canker sores (irritated tissues), thrush (which can sometimes appear as red patches), or (in rare cases) oral cancer.
• A bright red tongue can indicate that you have a vitamin B12 deficiency or an infection called scarlet fever — a Streptococcus bacteria infection in the throat (strep throat) accompanied by a red body rash. If you have bright red patches that don’t hurt and seem to migrate from one place on the tongue to another, you might have a harmless, incurable condition called “geographic tongue.”

Should you brush your tongue or use a tongue scraper?

Good oral hygiene requires that you floss your teeth at least once a day and brush them at least twice a day. Take a few seconds to use the brush on your tongue.

“Stick out your tongue and swipe your toothbrush from the back of your tongue to the front: one swipe down the middle, one swipe down the left side, and one swipe down the right side. That helps remove bacteria and debris that collect in papillae,” Dr. Jiang says.

Some people swear by using a tongue scraper to clean the tongue. Dr. Jiang isn’t a fan, but doesn’t have a problem with someone using the tool, which is pulled forward on the tongue in a similar fashion to brushing the tongue. “The data about tongue scraper effectiveness are mixed,” she says. “It just comes down to what you’re willing to do daily to keep your tongue, teeth, mouth, and gums as healthy as possible.”

Worried about your tongue? What to do

If you’re worried about anything wrong with your tongue — especially if you also have a fever, a very sore throat, sores that won’t go away, or other new symptoms — call your primary care doctor or dentist.

Your doctor or dentist can

• assess your condition
• prescribe or suggest treatments to relieve discomfort, such as medicated mouthwashes or warm-water rinses
• urge you to stay hydrated and step up your oral hygiene.

If necessary, your doctor can refer you to a specialist for further evaluation.

An F may mean failure in school, but the letter earns high marks in your diet. The two biggest dietary Fs — fiber and fermented foods — are top priorities to help maintain healthy digestion, and they potentially offer much more. How can you fit these nutrients into meals? Can this help your overall health as well as gut health?

Fiber, fermented foods, and the gut microbiome

The gut microbiome is a composed of bacteria, viruses, fungi, and other microorganisms living in the colon (large intestine). What you eat, the air you breathe, where you live, and many other factors affect the makeup of the gut microbiome. Some experts think of it as a hidden organ because it has a role in many important functions of the body — for example, helping the immune system function optimally, reducing chronic inflammation, keeping intestinal cells healthy, and providing some essential micronutrients that may not be included in a regular diet.

Your gut communicates with your brain through pathways in the gut-brain axis. Changes in the gut microbiome have been linked with mood and mental health disorders, such as depression and anxiety. However, it’s not yet clear that these changes directly cause these types of problems.

We do know that a healthy diet low in processed foods is key to a healthy gut microbiome. And increasing evidence suggests that fiber and fermented foods can play important parts here.

Fiber 101

Fiber’s main job is to make digestion smoother by softening and adding bulk to stool, making it pass quickly through the intestines.

But fiber has other benefits for your microbiome and overall health. A high-fiber diet helps keep body weight under control and lowers LDL (bad) cholesterol levels. Research has found that eating enough fiber reduces the risk of heart disease, type 2 diabetes, and some cancers.

What to know about fiber

There are two types of fiber: insoluble (which helps you feel full and encourages regular bowel movements) and soluble (which helps lower cholesterol and blood sugar). However, recent research suggests people should focus on the total amount of fiber in their diet, rather than type of fiber.

If you’re trying to add more foods with fiber to your diet, make sure you ease into new fiber-rich habits and drink plenty of water. Your digestive system must adapt slowly to avoid gas, bloating, diarrhea, and stomach cramps caused by eating too much too soon. Your body will gradually adjust to increasing fiber after a week or so.

How much fiber do you need?

The fiber formula is 14 grams for every 1,000 calories consumed. Your specific calorie intake can vary depending on your activity levels.

“But instead of tracking daily fiber, focus on adding more servings of fiber-rich foods to your diet,” says Eric Rimm, professor of epidemiology and nutrition at Harvard’s T.H. Chan School of Public Health.

Which foods are high in fiber?

Fruits, vegetables, legumes, nuts, seeds, and whole grains are all high in fiber. The Dietary Guidelines for Americans has a comprehensive list of fiber-rich foods and their calorie counts.

What about over-the-counter fiber supplements that come in capsules, powders that you mix with water, and chewable tablets? “If you have trouble eating enough fiber-rich foods, then these occasionally can be used, and there is no evidence they are harmful,” says Rimm. “But they should not serve as your primary source of dietary fiber.”

Fermented foods 101

Fermented foods contain both prebiotics — ingredients that create healthy changes in the microbiome — and beneficial live bacteria called probiotics. Both prebiotics and probiotics help maintain a healthy gut microbiome.

What to know about fermented foods

Besides helping with digestion and absorbing vital nutrients from food, a healthy gut supports your immune system to help fight infections and protect against inflammation. Some research suggests that certain probiotics help relieve symptoms of gut-related conditions like inflammatory bowel disease and irritable bowel syndrome, though not all experts agree with this.

Many foods that are fermented undergo lacto-fermentation, in which natural bacteria feed on the sugar and starch in the food, creating lactic acid. Not only does this process remove simple sugars, it creates various species of good bacteria, such as Lactobacillus or Bifidobacterium. (Keep in mind that some foods undergo steps that remove probiotics and other healthful microbes, as with beer or wine, or make them inactive, like baking and canning.)

The exact amounts and specific strains of bacteria in fermented foods vary depending on how they are made. In addition to probiotics, fermented foods may contain other valuable nutrients like enzymes, B vitamins, and omega-3 fatty acids.

How often should you eat fermented foods?

There is no recommended daily allowance for prebiotics or probiotics, so it is impossible to know precisely which fermented foods or quantities are best. The general guideline is to add more to your daily diet.

Which fermented foods should you choose?

Fermented foods have a range of tastes and textures because of the particular bacteria they produce during fermentation or that are added to foods. Yogurt is one of the most popular fermented foods (look for the words “live and active cultures” on the label). Still, many options are available if you are not a yogurt fan or want to expand your fermented choices. Kimchi, sauerkraut, kombucha, and pickles are a few examples.

As with fiber, probiotics are also marketed as over-the-counter supplements. However, like all dietary supplements, they do not require FDA approval, so there is no guarantee that the types of bacteria listed on a label can provide the promised benefits — or are even in the bottle. “Therefore, it is best to get your probiotics from fermented foods,” says Rimm.

It’s not often that a new drug comes along that could help nearly a quarter of the adult population. But when it does, you can bet you’ll see ads for it on TV and the Internet.

That’s the case with Veozah (fezolinetant), a medicine for hot flashes and night sweats due to menopause that was approved by the FDA in May 2023. One ad has this inventive tagline: “You can have fewer hot flashes and more not flashes.”

So, what is a not flash and what does the ad tell us about this new drug?

The ad: This is a not flash

The ad begins with an upbeat song, “Good Feeling,” a hit by Flo Rida released in 2011. A woman in a crowded elevator is clearly distressed and soaked in sweat as the voiceover declares, “This is a hot flash.” A second woman appears, awakening in her bedroom covered in sweat. Again, the narrator declares “This is a hot flash.” Cut to two smiling women on a dock taking selfies as boats sway behind them: “But this is a not flash.”

The voiceover tells us that Veozah is a prescription treatment for women with moderate to severe hot flashes and night sweats — or vasomotor symptoms, as medical experts say. (Hot flashes may or may not prompt sweating, while night sweats are exactly as billed.)

When the voiceover tells us the drug is “hormone free,” the words “100% hormone-free” appear on the screen. Got it? Apparently, this drug contains no hormones.

Does Veozah work?

But is it effective? The ad voiceover says, “Veozah has been proven to reduce the number and severity of hot flashes day and night. For some women, it can start working in as early as one week.”

The details are easy to miss. They appear in fine print briefly at the bottom of the screen: “At 12 weeks, women taking Veozah experienced 63% fewer hot flashes vs. 42% on placebo.” Sounds good, right? More on what this actually means below.

What does the ad tell us about risks?

The FDA requires drug manufacturers to review the most common or serious risks of taking the drug. So while the catchy song continues, images appear of women peacefully sleeping, teaching a classroom full of students, or working in a hectic office. The voiceover warns that some people shouldn’t take Veozah: anyone with cirrhosis (a form of liver disease) or severe kidney problems, and anyone who takes a medicine known as a CYP1A2 inhibitor.

Next comes the litany of possible side effects, including:

• the need for repeated liver blood tests before and during treatment
• stomach pain
• diarrhea
• difficulty sleeping
• back pain.

What does the ad get right?

This ad highlights significant suffering caused by hot flashes and night sweats, which affect about 80% of women during menopause. Currently, treatment options (and, truth be told, actual research on those dealing with these problems) are quite limited. Hormone replacement with estrogen and related medicines was often prescribed in past years. But concerns about risks associated with estrogen use led many physicians to stop prescribing hormone replacement, and many women decline it when it’s offered.

But Veozah works without hormones: it blocks a protein in the brain that helps regulate body temperature. That’s why the “hormone free” message is emphasized in the ad.

Just how effective is Veozah for hot flashes and night sweats??

Unfortunately, digging more closely into the data shows the difference between Veozah and placebo in reducing hot flashes and night sweats is relatively small. And some important information is missing or incomplete in the ad. I filled in gaps by looking at two pivotal trials of Veozah (called SKYLIGHT 1 and SKYLIGHT 2).

What exactly are “moderate” and “severe” symptoms?

For this study, women had to have at least seven moderate to severe hot flashes per day, although the average was 10 to 12. A moderate hot flash was defined as a sensation of heat with sweating that did not interfere with activities. A severe hot flash was a sensation of heat with sweating that did interfere with activities. So, the number of moderate or severe hot flashes tallied by the researchers in this study included sweats, regardless of what time of day they occurred.

How many hot flashes or night sweats were prevented?

The ad provides data on effectiveness as a percent reduction: 63% fewer hot flashes. Importantly, that doesn’t tell you the actual number of hot flashes prevented. During 12 weeks of treatment, women given the medicine went from experiencing an average of about 11 hot flashes a day at the start to about four a day. By comparison, the group taking a placebo (an inactive pill) dropped from 11 hot flashes a day to 6.5 a day. So, that’s about 2.5 fewer hot flashes a day in total for women taking the drug.

• What about effectiveness after 12 weeks? Based on the published studies (including SKYLIGHT 4), effectiveness persists for at least a year with continued treatment. While that’s good news, it would be helpful to know whether effectiveness wanes or persists beyond one year, because menopausal hot flashes and night sweats can come and go for many years. The average is about seven years, and it’s not rare for them to last a decade or more.
• How diverse were the study participants in the clinical trials that led to FDA approval? More than 80% of study participants identified as Caucasian, 17% as African American, 24% as Hispanic/Latina, and 1% as Asian. Studies of a more diverse population are needed.

What else should you know about possible downsides of Veozah?

The ad covers the most common side effects reported during trials of this drug. Yet advising people to avoid Veozah if they take a CYP1A2 inhibitor is likely to perplex most viewers. This warning relates to an enzyme that helps the body metabolize many medicines, including Veozah.

If you’re already taking a medicine that inhibits the action of this enzyme and you start taking Veozah, the blood levels of Veozah may rise higher than intended and increase the risk of side effects. Many common medicines can cause this interaction (including ciprofloxacin, some oral contraceptives, and cimetidine). Ask your doctor about this before starting Veozah.

Finally, the ad provides no information about cost. According to the drug maker’s website, the list price is $550 a month. That’s the amount you’d be charged if you have no health insurance.

But the average price for people with commercial health insurance is $41 a month. It’s about $77 a month for people covered by Medicare Part D, and $12 a month for people with Medicaid. The drugmaker’s Patient Assistance Program may provide the drug at no cost for some people who are eligible — though eligibility criteria aren’t easy to find and aren’t included in the ad.

The bottom line

A newly approved, nonhormonal drug for hot flashes and night sweats during menopause is big news. But it remains to be seen whether this is a small step forward or a major advance. Either way, the ad mostly does its job: it introduces us to a new medication for a common and burdensome condition that currently has limited treatment options.

Of course, this one-minute ad for Veozah isn’t intended to cover everything a viewer might want to know about it; it’s intended to get people with significant hot flashes and night sweats to ask their doctor about the advertised drug. Keep that in mind when you see ads for this drug — or any drug ad, for that matter.

While I’m not sure whether Veozah will prove to be a wonder drug, one thing’s for sure: that song sure holds up well.

One of the more unusual conditions affecting the hands and fingers is Dupuytren’s contracture (also called Dupuytren’s disease). Here, one or more fingers become curled, which can make it difficult to pick up or hold objects or perform everyday activities.

Legend says the condition originated with the Vikings of Northern Europe, although this is debated. It was later named after the 19th-century French surgeon Guillaume Dupuytren, who did the first successful operation on the condition. Fast-forward to the 21st century, and Dupuytren’s contracture now affects about one in 20 Americans.

What is Dupuytren’s contracture?

Fascia is a sheet of fibrous tissue beneath the skin of the fingers and the palm. Dupuytren’s contracture is a thickening and shortening of this tissue.

This thickened area begins as a hard lump called a nodule. Over years to decades, it may progress to a thick band called a cord that causes one or more fingers to curl toward the palm and become stuck in a bent position. This can make it difficult to grasp objects, button clothes, use a computer, or perform other daily tasks.

The condition does not always get progressively worse. It may be stable for years or even improve in some people.

Which fingers are most likely to be affected?

The ring and pinky fingers are most often affected. But the condition can strike all fingers and the thumb.

“In about half of cases, the condition can affect both hands,” says Dr. Phillip Blazar, an orthopedic surgeon and Division Chief of Hand and Upper Extremity at Harvard-affiliated Brigham and Women’s Hospital. Fortunately, it rarely causes pain.

What causes Dupuytren’s contracture?

Currently, the cause is unclear. Still, several factors can increase a person’s risk, such as

• Genetics: This condition is more common in people with Northern European, British Isles, or Scandinavian ancestry.
• Gender: Men are affected more often than women.
• Age: The condition often occurs after age 50.
• Family history of the disease.

People with diabetes and seizure disorders are also more likely to have Dupuytren’s. The condition may appear and/or worsen after trauma to the hand.

How is Dupuytren’s contracture treated?

Although there is no cure, treatments and occupational or physical therapy can help address symptoms and improve finger mobility. “Many people who have mild cases of Dupuytren’s find it has little impact on their ability to use their hands,” says Dr. Blazar.

However, moderate or severe cases can interfere with hand function. It’s possible to restore normal finger motion with nonsurgical treatments, such as:

• Collagenase injection. This procedure is done in the doctor’s office. An enzyme called collagenase is injected into the cords of your hand, which breaks down and dissolves the thickened tissue. At a follow-up visit, your doctor will give you local anesthesia and then snap the cords by manipulating and straightening your fingers in the direction in which they are unable to move.
• Needle aponeurotomy. This in-office procedure involves passing a hypodermic needle back and forth through the restrictive cords to weaken and break them.

“Your hand surgeon will discuss both treatment options to determine which is best for your situation,” says Dr. Blazar. “There are also some variations in the anatomy of the disease which may make one treatment or the other less favorable for a particular person or finger.” Both of these treatments don’t remove the cords, and the condition can return and require additional treatment.

What about surgical treatment?

If nonsurgical treatment does not relieve symptoms or you have a severe condition, surgery may be recommended. Surgical approaches include:

• Fasciotomy. An incision is made in your palm to divide the thickened tissue in the cord.
• Subtotal palmar fasciectomy. A zigzag incision is made along the creases in the hand to remove the abnormal tissue and cord. Occasionally, a skin graft may be needed to help the wound heal.

You wear a splint on the repaired hand during recovery. People should expect some pain, stiffness, and swelling afterward. The length of recovery varies for each individual, and also with how many fingers were operated on and which ones.

“Most people largely recover by three months, but some may not feel fully recovered for quite a bit longer,” says Dr. Blazar. Hand therapists can also help with strength and flexibility exercises to speed recovery.

Most people’s fingers move better after surgery. However, as with nonsurgical treatments, the contracture can come back, so some people may need additional surgery later on.
