By Ginger Nichols, Licensed Certified Genetic Counselor at MotherToBaby Connecticut

I was pregnant in 2004 when the Food and Drug Administration (FDA) and the U.S. Environmental Protection Agency (EPA) released guidelines on limiting fish consumption in pregnancy because of methylmercury. That pregnancy was definitely the most amazing time of my life; however, it was also stressful. It was the 5th time I had been pregnant, but due to miscarriages and the death of a son who was born very prematurely, I had yet to bring a baby home from the hospital. I became hyper-vigilant about anything that might be a possible exposure of concern for a pregnancy. I freely admit that my frame of mind for that pregnancy could not be called logical. Therefore, with the new and somewhat scary information about fish and methylmercury, fish was quickly added to my list of “don’t eat that.” I also admit that I don’t eat the recommended amount of fish anyway, so it was not that big of a leap to stop eating all fish.

It turns out that I wasn’t the only ‘fish out of water.’ According to a FDA study of the dietary habits of over 1,000 pregnant women in the U.S., around 21% of the women said that within the past month they had eaten zero fish. For the women who said that they did eat fish, most were eating less than the recommended dietary guidelines. However, fish is healthy for you! You don’t want to stop eating fish altogether, so instead of avoiding fish, let’s learn the facts.

By now, you may be asking: “What is methylmercury and why is it in fish?” As a Genetic Counselor and MotherToBaby specialist, I often talk to women about eating fish during pregnancy, so let me explain…. Methylmercury is an organic form of mercury. Mercury occurs naturally in the environment and it is also released into the air as a by-product of some industrial processes. When mercury gets into the soil and the water (including lakes, rivers, and the ocean), bacteria and fungi found in soil and water change mercury into methylmercury. Since methylmercury is in our water, it is found in different levels in pretty much all fish and shellfish. In general, larger fish with long life spans that eat other fish are typically going to have higher levels of methylmercury than smaller, younger fish. If you are interested, there are lists of average mercury levels in fish available online, such as this FDA web site: https://www.fda.gov/food/foodborneillnesscontaminants/metals/ucm115644.htm

Methylmercury is found in all tissues of the fish, so cleaning or cooking the fish will not reduce the levels of mercury. People who eat a lot of fish with high levels of methylmercury can also accumulate methylmercury in their bodies. Our bodies easily absorb methylmercury from our gastrointestinal (GI) tract and it takes a long time for our bodies to get rid of it.

“So why should I be concerned about eating too much seafood with high levels of methylmercury?” We know that even if you are not pregnant, methylmercury is toxic to our nervous system and organs. The effects of methylmercury poisoning have been known since the 1950s. People who became sick from methylmercury poisoning had many symptoms that included numbness in the hands and the feet, muscle weakness, tremors (shaking), and personality changes (irritable, shy, nervous). Now before you panic, be aware that these people had been exposed to fish with levels of methylmercury far higher than even the most contaminated fish in your grocery store!

We know that methylmercury can cross the placenta in pregnancy. With very high exposures, babies have been born with small head size and brain damage that can lead to seizures, developmental delay, blindness, and muscle weakness. Since methylmercury can affect the baby’s developing brain, high exposure is a concern at any stage of pregnancy. For more info, visit the MotherToBaby fact sheet on methylmercury in pregnancy and breastfeeding at https://mothertobaby.org/fact-sheets/methylmercury-pregnancy/.

By now you may feel like you just need to stay away from eating fish in pregnancy, when in fact studies are showing that women who eat fish during pregnancy have better pregnancy outcomes than women who do not eat fish. Recent studies have also looked at how nutrients in fish, including Omega-3 fatty acids, might have positive effects for baby’s development and actually may help to protect against any possible harm that might occur from prenatal methylmercury exposure. And what’s more, women in the U.S. generally do not depend upon fish as their only protein intake, so are unlikely to eat enough fish to cause harmful effects in a pregnancy. So, to reap the full health benefits of fish consumption for you and baby, the key is to eat a variety of fish that are low in methylmercury. This is where the FDA’s updated 2017 guidelines can provide some assistance.

“What are the current FDA guidelines?” The FDA’s recently revised advice is designed to encourage women who are pregnant and/or breastfeeding to consume up to 12 ounces of fish that are low in methylmercury each week, and provides guidance on which fish are the best options by breaking the fish into categories of Best Choices, Good Choices, and Choices to Avoid. The easy-to-read guide can be found here: https://www.fda.gov/downloads/Food/ResourcesForYou/Consumers/UCM536321.pdf. You’ll notice that on the FDA’s guide, different types (species) of tuna and tilefish are listed under different categories – so take note of which type you are buying so you know which list it is on.

Following current recommendations, if you are planning to become pregnant, currently pregnant, or currently breastfeeding:

• A typical serving of fish is 4 to 6 ounces, measured before cooking.
• Each week, you may eat up to 2-3 servings of a variety of fish from the Best Choices list; there are over 35 different types of fish on this list!
• If choosing a fish from the Good Choices list, limit yourself to just the one serving of that fish for the week.
• Avoid the following fish, as they are highest in methylmercury: shark, swordfish, mackerel, marlin, orange roughy, bigeye tuna, and tilefish from the Gulf of Mexico.
• If you are eating fish caught by family or friends, check for local fish advisories. The EPA has a search option to check for fish/shellfish advisories based on where you live: https://fishadvisoryonline.epa.gov/General.aspx. You can also check in with your state Department of Public Health. If there isn’t an advisory, limit yourself to just one serving of that fish and do not eat any other fish that week.

So now that we’ve got you on the hook and reeled you in, what’s the takeaway? With around 60 fish listed as Best and Good Choices on the FDA’s 2017 fish guidelines, ‘there are plenty of fish in the sea’ for pregnant and breastfeeding moms!

At some point, most of us have been told to “eat healthy.” Sounds simple enough, right? But what that means can look different from person to person. For some, it’s about cutting back on junk food and adding more fruits, vegetables, and whole grains. For others, it might mean watching sodium intake, choosing foods that support heart health, or managing cholesterol levels.

No matter your health history, eating well is something we’re all encouraged to do, especially during pregnancy and while breastfeeding, when your body is supporting both you and your baby.

But if you’re living with an eating disorder, pregnancy or breastfeeding can add extra layers of complexity. It’s not just about what to eat anymore: questions about how much to eat, how often to eat, and how to manage hunger cues or body changes can feel overwhelming. These challenges are real, and they deserve thoughtful, compassionate support.

A few years ago, I received a call from a woman named “Alice.” She called MotherToBaby because she was taking medication for high blood pressure and wanted to know if it would affect her pregnancy. After some discussion, she told me her blood pressure was high because she was quickly gaining a lot of weight from binge eating. She said she had been binge eating for a long time and did not know how to stop. She was worried about how this would affect not only her health, but also that of her baby. When I asked what her healthcare provider suggested, she told me she was afraid to talk to her midwife about it.

What is an eating disorder?

An eating disorder is a mental health disorder that results in serious disturbances of eating behavior. There are several different eating disorders, including anorexia nervosa, bulimia nervosa, binge eating disorder, and pica. Each disorder has its own symptoms and effects. In the United States, 9% (28 million) of people will have an eating disorder in their lifetime.

• Anorexia nervosa –severely restricting the amount of food eaten, resulting in very low body weight.
• Bulimia nervosa – binge eating (eating large amounts of food in a short time and feeling loss of control overeating) and then purging (vomiting, not eating, over-exercising, misusing laxatives or diuretics).
• Binge-eating disorder- binge eating without purging.
• Pica – a craving for and eating of substances without any nutritional value (such as ice, clay, paper, or dirt) for at least one month. The number of women affected by pica is unknown, but it is much more common in pregnant women than in non-pregnant women; it is also more common in developing countries than in the US.

Eating disorders can be hard to spot under any circumstances, and that can be even more true during pregnancy and after a baby is born. So much focus is placed on weight changes, appetite shifts, and body changes during this time that warning signs can easily be overlooked or explained away as “just part of pregnancy.” Also, not all healthcare providers receive specialized training in recognizing eating disorders, especially in pregnant or postpartum patients. That means symptoms can sometimes go unnoticed, even during regular prenatal or postpartum visits.

There’s also a lot of stigma surrounding eating disorders. Some women may feel embarrassed, ashamed, or afraid to speak up about their struggles. Others might worry about being judged or not being taken seriously. All of that can make it incredibly difficult to admit that something isn’t okay.

Can eating disorders affect my pregnancy?

A healthy, well-balanced diet during pregnancy is important for a fetus to grow and develop. It can also help to minimize some pregnancy symptoms such as nausea and constipation. Certain eating-disorder behaviors can cause issues during pregnancy and may require hospitalization or other specialized care. For example:

• Not eating and/or calorie restriction can cause low energy and nutritional gaps in the mother and low birth weight for the baby.
• Vomiting can cause dehydration, electrolyte imbalances, sore throat, stomach pain, tooth damage, gum disease, and ruptured esophagus in the mother.
• Using laxatives/diuretics can cause dehydration, electrolyte imbalances, laxative dependency, and organ damage in the mother.
• Over-exercising can lead to fatigue, muscle pain/soreness, dehydration, and overheating in the mother.
• Binge eating can lead to excessive weight gain, gestational diabetes, high blood pressure (and other complications) in the mother, and large birth weight for the baby.
• Eating non-food substances (pica) can interfere with nutrient absorption and may contain dangerous substances that could be harmful to mom or baby. See our fact sheets on toxoplasmosis and lead.
• Mental health issues, such as depression or anxiety, go hand in hand with eating disorders. Learn more about how mental health disorders can affect pregnancy and breastfeeding.

What about breastfeeding?

Getting sufficient “high quality” calories is important for everyone. During breastfeeding, the body needs energy to make enough milk, and not getting enough calories can make it harder to do. For pica, non-food items may contain something potentially harmful to the baby, such as lead.

Studies have suggested that women with eating disorders might be more likely to stop breastfeeding within the first 6 months. However, it is possible to successfully breastfeed with an eating disorder, even if they are taking medications. The key is finding support, which you can get from healthcare providers (doctors, nurses, lactation consultants), family, friends, and support groups (online, over-the-phone, and in person).

Help is Available

If you have been diagnosed with an eating disorder, or think you may have one, talk with your healthcare provider. You are not alone. There are resources available to help you and your baby be as healthy as you can be.

Talk to your healthcare provider to discuss how many calories per day are right for you. There are many resources available to help educate people about good food choices, such as the Americal College of Obstetrics and Gynecology’s Frequently Asked Questions on healthy eating during pregnancy. The National Institutes of Health has information on which foods/drinks to limit/avoid, the appropriate amount of weight to gain, and the recommended amount of exercise.  

And finally…

So, what happened to Alice? She called several times throughout her pregnancy and while breastfeeding. After our first conversation, she told her midwife everything. Alice did develop gestational diabetes, but under the care of her midwife, nutritionist and counselor, she was able to stop gaining weight and get her blood sugar and blood pressure under control. She gave birth to a healthy baby and continued to work with her team during breastfeeding. She thanked me for suggesting she ask for help and said she was closer to finding something we all are looking for – balance.

Baby it’s cold outside…and ‘tis the season for MotherToBaby to answer questions about cough and cold medications while breastfeeding. 

Some “Cold” Hard Facts

Factors such as your baby’s age and whether they were born prematurely or have chronic health problems matter.  Very young babies (less than 3 months old) may have a more difficult time metabolizing medications in the milk and may be more susceptible to side effects like sleepiness.  Milk is also their complete diet, and some medications can reduce your milk supply.  The older your baby is, the less likely it is that the medication will cause a serious problem in your baby, but it is still a good idea to be careful.  We also consider how much of the medication typically ends up in breastmilk, and whether the medication is considered acceptable to give directly to a baby.

Many cough and cold medications come in combination products.  In some cases, you end up taking extra medications for a symptom you do not have!  Also, some medications act together to make more problems.  For example, decongestants and antihistamines taken together may have extra ability to reduce milk supply.  Taking a single medication at a time lets you be sure you are using only the one that you need.

Consider whether your symptoms need medical treatment…is it worth the potential exposure to your baby, especially since many medications have not been studied very well in breastfeeding?  Non-medication strategies like a humidifier, warm shower or bath, or nasal irrigation with saline may be comforting.

Most vitamins or minerals taken over the recommended daily allowance (RDA) have not been studied very well in breastfeeding. Herbal agents are also poorly studied, which makes it difficult to tell if they are hazardous or not in breastfeeding. In general, supplements like this should be avoided.

Fever and Body Aches

Common medications to treat these symptoms are acetaminophen and ibuprofen.  Both end up in breastmilk in only small amounts and can be given directly to babies. When used as recommended on the label these medications are unlikely to harm your baby.

Aspirin is not given to babies because it may cause bleeding or a condition called Reye syndrome (swelling of the brain). Very little aspirin gets into breastmilk, but to be on the safe side you may want to be cautious about taking it when you are breastfeeding unless it is prescribed for a medical condition and your baby’s health provider agrees with use.

The Sniffles (medications that dry up your nose like decongestants and antihistamines)

Over-the-counter nasal decongestants fall into two categories: oral and topical/spray.

Oral (pill) decongestants include pseudoephedrine and phenylephrine. These medications are not given directly to babies and can make them jittery and sleep poorly, and may also reduce your milk supply. 

Oral (pill) antihistamines include chlorpheniramine, doxylamine, and diphenhydramine. Varying amounts get into milk; they can make your baby sleepy or irritable, and may reduce your milk supply.  They are also not medications given directly to babies.

Topical (spray) decongestants such as oxymetazoline have not been studied very well in breastfeeding.  However, they are not very well absorbed from your nose, and thus not much is likely to get into your milk.

Cough

The most common over the counter cough medications are dextromethorphan (cough suppressant) and guaifenesin (loosens up mucous).  Not much dextromethorphan gets into milk; it is not known if guaifenesin gets into your milk.  Some cough syrups contain alcohol, which would be a hazard for your baby.  Be sure to check your label.

Cough lozenges may just have sugar and flavoring, or may include honey, menthol, zinc, or herbal agents.  Read your label before you take the medicinal ones since many components have not been studied very well in breastfeeding.

We hope you feel better soon, and if you have further questions or notice side effects in your baby that you suspect may be related to a medication you are taking, speak with your baby’s healthcare provider.

The weeks after delivery (often called the fourth trimester) can raise just as many questions as pregnancy itself. From pain management and supplements to beauty treatments and mental health medications, many parents are unsure how different exposures may affect breastfeeding.

In this episode of The MotherToBaby Podcast, host Chris Stallman, MS, CGC, is joined by Kirstie Perrotta, MPH, and Angela Messer, MS, Teratogen Information Specialists from MotherToBaby California, to discuss some of the most common postpartum questions they receive from parents and healthcare providers.

Together, they explain how exposure information is evaluated during breastfeeding and how factors like dose, timing, and route of exposure influence what may reach breast milk.

In This Episode, You’ll Learn:

• What the fourth trimester is and why exposure questions continue after delivery
• Common postpartum concerns, including pain medications, stool softeners, and laxatives
• How prescription pain medications, including opioids, are evaluated during breastfeeding
• Why route of exposure matters when considering topical products
• What to know about hair dye, Botox, manicures, facials, and salon treatments
• Why supplements, herbal products, and proprietary blends raise additional questions
• Which over-the-counter medications are often discussed in the breastfeeding period
• How medication guidance can differ between pregnancy and lactation
• Why addressing postpartum mental health conditions is essential
• Common breastfeeding myths and misconceptions
• Practical tips to reduce direct infant contact with topical products

Key Takeaways:

• Many medications have data available for use during breastfeeding
• Topical products are typically evaluated based on how they are applied and absorbed
• High-dose supplements and proprietary blends often lack breastfeeding data
• Postpartum pain, mental health, and chronic conditions deserve appropriate treatment
• Feeding decisions are personal, and there is no single approach that works for everyone

Resources Mentioned:

• MotherToBaby.org – evidence-based fact sheets, Baby Blogs, podcasts, and educational resources
• Over 300 fact sheets in English and Spanish on medications, exposures, and health conditions
• One-on-one support via phone, chat, text, or email
• MotherToBaby Pregnancy Studies – helping expand knowledge about medications, conditions, and exposures in pregnancy and lactation

The New Year often brings thoughts of finding a new job. Even those happy in their current occupations often use the New Year to jump start career advancements. If you are thinking about a pregnancy, or you are already pregnant or breastfeeding, chances are you have also started to think more about potential exposures that might be of concern.

As a prenatal genetic counselor, I have noticed a common trend among working women. Many women do not worry very much about potential work hazards when first starting their careers. However, once they start to plan a pregnancy or find out that they are pregnant, many women call to ask about job safety. With a new life is on their minds, many women start to view their environment more critically.

For those of you planning a pregnancy, now is a great time to ask your questions about workplace safety with your healthcare providers or to contact a MotherToBaby specialist. Researching possible occupational exposures prior to pregnancy can allow time to decide if extra safety measures should be considered. Don’t forget to think about occupational exposures that your partner might be facing.

Occupational hazards can include:

• chemicals,
• metals,
• anesthetic gases,
• ionizing radiation,
• loud noise,
• extreme heat or extreme cold,
• strenuous physical exertion,
• repetitive movements,
• whole body vibration,
• infectious agents (viruses, diseases),
• injury,
• emotional stress and
• changing shift rotations.

In general, exposures can happen through: inhaling substances (e.g., breathing a gas, powder, dust or vapor into your lungs), absorption through skin, or ingestion (i.e., eating or drinking).

Sometimes, workers carry hazardous substances (dust, powder, chemicals, metal flakes) home on their shoes or clothing. This is one of the reasons that it is also important talk to your partner or other adults living in your home about their workplace.

While the list of potential hazards looks long, we should remember that just because we work around a potential hazard, it does not mean that we are actually exposed to the hazard. More importantly, employment has generally been considered beneficial for maternal health and birth outcomes. This is due to the financial and social benefits of working, and some call it the “healthy worker effect”. Most of the health problems that have been associated with workplace exposures do not affect our ability to get pregnant or to carry a healthy pregnancy to term.

The United States Department of Labor’s Occupational Safety and Health Administration (OSHA) requires employers (your bosses) to make the workplace safe for their workers. But, workplace safety measures were mainly created with adults (men and non-pregnant women) in mind; not a developing baby. In addition, workplace hazards that might affect a pregnancy are difficult to research. Therefore, your healthcare providers might not always know how a true exposure could affect a pregnancy. However, by following proper safety procedures, workplace exposures will likely be kept below levels that would affect your health or a pregnancy.

What should I be ready to discuss if I am worried about possible exposures at my workplace?

1. Employer/Job title
2. How long you’ve been working there
3. Description of job tasks, during and prior to pregnancy
4. Exposures that you are worried about
5. Personal protective equipment used (such as gloves, gowns, masks, or eyewear)
6. Ventilation at the work site (e.g., are there Hoods? Air Handlers? Fans? Windows that can open?)
7. Eating or drinking at the work site (e.g., do you store your food in an area that is designated only for that purpose?)
8. Any health symptoms in you or coworkers
9. Any reports available, such as blood lead levels, air quality reports, or water report.
   1. Sometimes an industrial hygienist will come to a work site to visually look at the work place or to take test samples (air, water, surfaces) for contamination.
10. For those who work around chemicals, they may ask about Safety Data Sheets (more on these below).
11. Other jobs/hobbies during pregnancy

What are Safety Data Sheets?

The best way to find out what chemicals are in the product(s) you use at work, or products that are used around you, is to get a copy of the Safety Data Sheets (SDS) (previously called Material Safety Data Sheets, or MSDS). SDS are prepared by chemical manufacturers and outline information on the product. Your workplace is required to have the SDS readily available to workers for all hazardous chemicals used at a worksite. Most SDS / MSDS can also be downloaded from the internet.

Along with listing hazardous ingredients, the SDS will talk about how to handle and store the product. The sheet should also talk about any specific recommendations for PPE and how to clean a spill or how to apply immediate first aid in case of accidental exposure.

Sometimes, a hazardous ingredient may be listed as “trade secret” or “proprietary formulation”. One can try to learn more about the chemicals in the proprietary formulation by contacting the manufacturer at the address or telephone number listed on the SDS. If a product contains no hazardous ingredients, it will be listed as such.

Along with a list of ingredients considered hazardous, the SDS may also discuss allowable levels of exposure. You may have heard of these limits by the terms: the Threshold Limit Value (TLV) or Permissible Exposure Limit (PEL). TLVs and PELs are limits for the maximum exposure allowed in the workplace. Industrial hygienists can perform workplace assessments to determine if there are exposures that are above allowable levels. These limits are designed to minimize health effects in nonpregnant workers. So it cannot be assumed that exposure levels below the TLV or PEL will be safe for a pregnant woman and/or her fetus.

What kind of safety protection can be used?

All work places should provide the proper personal protective equipment (PPE) for handling and working around hazardous situations. Some examples of PPE include gloves, shoes, aprons, gowns, ear protection, masks, and/or ventilation such as hoods and air filters.

• Use the PPE that is recommended for your job.
• Use PPE at all times, not just when pregnant.
• Keep your training on how to properly use the PPE up to date.
• Make sure hoods, respirators, and other equipment are working properly.
• If you wear PPE (such as a respirator), be sure it fits correctly. And keep in mind: as a woman’s body changes during pregnancy, PPE may need to be re-fitted.
• If you wear a respirator, remember that respirators are not a substitute for appropriate permanent exhaust ventilation (such as fume hoods, exhaust ducts and/or exhaust fans). Respirators are designed to be used only for a short period of time.
• If the right PPE is not currently at your worksite, ask your employer about getting it.

Consider talking with an occupational health specialist or industrial hygienist who may be able to provide information that is specific to your workplace.

How can I learn more about ways to reduce my exposure to potential hazards in my workplace?

MotherToBaby has a fact sheet that discusses general tips on working safely called Reproductive Hazards of the Workplace. There are some other fact sheets on specific occupational exposures, such as infectious diseases, lead, paint, and pesticides. There are also specific workplace sheets that look at working in a veterinary setting, in a nail salon, and for those who work with x-ray machines. Our entire library of fact sheets can be accessed by visiting https://mothertobaby.org/fact-sheets-parent/.

You can also contact an industrial hygienist or occupational medicine specialist. Try looking for them at a local medical university or through the American Industrial Hygiene Association: https://www.aiha.org/about-ih/Pages/Find-an-Industrial-Hygienist.aspx. Industrial hygienists should be able to provide an independent assessment on ways to improve the safety of your job, if needed, and may be able to give advice on how to work with employers in implementing these changes. The National Institute for Occupational Safety and Health (NIOSH) has a free service called Health Hazard Evaluation (HHE), which can provide you or your employer advice about health hazards that might be in your workplace and can offer tips on how to make your workplace safer. To learn more, visit the NIOSH website at: https://www.cdc.gov/niosh/hhe/.
