The postpartum period is a time of significant physiological and emotional adjustments for new mothers. While caring for a newborn, many women also focus on regaining their pre-pregnancy bodies. Weight loss after childbirth can be challenging, and some mothers turn to medications like Ozempic for assistance. Ozempic, a brand name for semaglutide, has gained popularity for its effectiveness in weight management and blood sugar control. However, its safety and appropriateness during the postpartum period, especially while breastfeeding, require careful consideration.
Understanding Ozempic and GLP-1 Receptor Agonists
Ozempic belongs to a class of medications known as GLP-1 receptor agonists. GLP-1, or glucagon-like peptide-1, is a naturally occurring hormone in the body that plays a crucial role in regulating appetite and glucose metabolism. GLP-1 receptor agonists mimic the action of this hormone, helping to lower blood sugar levels, slow down digestion, and reduce appetite.
Semaglutide, the active ingredient in Ozempic, has a 94% structural similarity to human GLP-1. This medication works by binding to GLP-1 receptors, which inhibits glucagon release from the alpha cells of the islets of Langerhans in the pancreas. This process helps to stabilize blood sugar levels and lower post-meal glucose spikes.
Other GLP-1 receptor agonists include medications like Victoza (liraglutide) and Trulicity (dulaglutide). Mounjaro (tirzepatide) is a similar type of weight loss drug that works in a slightly different way, targeting both the GLP-1 receptor and the GIP (glucose-dependent insulinotropic polypeptide) receptor.
The "Ozempic Baby" Phenomenon
Weight loss, particularly when significant, can impact fertility. GLP-1 receptor agonists like Ozempic regulate appetite and insulin, often leading to substantial weight loss. Carrying extra weight can make it more challenging to conceive, both naturally and through fertility treatment. Excess weight can also contribute to medical conditions that interfere with fertility, such as polycystic ovary syndrome (PCOS).

Losing weight can improve the likelihood of conceiving for women who were overweight or obese. "Ozempic babies" refer to surprise pregnancies in people taking GLP-1 receptor agonists. This can occur as weight loss reduces estrogen production from fat cells, signaling the body to prepare for pregnancy. Additionally, GLP-1 receptor agonists slow down the rate at which food moves through the body, which can affect the absorption of oral contraceptives.
Ozempic and Pregnancy
If you're taking Ozempic or another GLP-1 receptor agonist and become pregnant, it’s important to contact your OB/GYN or another medical provider. These medications were not studied in pregnant women during clinical trials, so their effects on an unborn baby are unknown. Your provider can recommend a strategy for safely navigating pregnancy.
GLP-1 medications like Ozempic aren’t appropriate for pregnant women. Animal studies have demonstrated a variety of adverse effects during pregnancy, including decreased fetal growth, skeletal abnormalities, and even miscarriage. Weight loss is generally not recommended during pregnancy, with or without medication.
Postpartum Use of Ozempic: Key Considerations
The use of Ozempic postpartum is a complex issue with no universal guidelines, especially for breastfeeding mothers. While some postpartum parents can safely take GLP-1s, they’re not recommended for those who are breastfeeding.
Safety During Breastfeeding
There's very limited research looking at GLP-1 use during breastfeeding, so most experts advise steering clear, especially early on in your breastfeeding journey.

Potential Risks:
- Insufficient Calorie and Nutrient Intake: GLP-1s cause a person to take in far fewer calories, which is a concern since breastfeeding bodies need around 500 more calories per day than the average person. Less calories, vitamins, and minerals might also mean that you feel more tired or become more prone to nutritional deficiencies too.
- Dehydration: GLP-1s can also make you less thirsty, setting the stage for dehydration at a time when your body needs more fluids than usual.
- Reduced Milk Production: A lack of fluids and nutrients could result in a GLP-1 tanking a nursing mom's milk supply.
- Compromised Milk Quality: Even though the drugs don't appear to transfer into breast milk, it's possible that your milk's nutritional content could go down. If Ozempic is changing the way a mom is eating, it can result in changes to the nutrient content of her milk.
It’s essential to consider that exclusive breastfeeding is more nutritionally demanding than late pregnancy, requiring up to an additional 500 kcal per day. This is because the lactating mother continues to provide the entirety of the infant’s nutrient needs for the first six months of life.
A study investigating the transmission of semaglutide into human milk found that semaglutide was not detected in any of the collected human milk samples. The maximum relative infant dose (RID) projected was 1.26%, far below the standard 10% safety threshold. While this suggests that semaglutide concentrations in human milk are unlikely to pose clinical concerns for breastfed infants, questions about long-term infant outcomes, the safety of maternal nutrient intake, and the nutrient content of breast milk remain.
When GLP-1s Might Be Considered During Breastfeeding:
Consider starting the meds once your little one has started solids. "If a baby is getting nutrients from somewhere other than their mom's milk, there's less of a risk for nutrient deficiency. Make sure you keep meeting your nutritional needs by taking a multivitamin if necessary.
Safety When Not Breastfeeding
- Timing: Non-breastfeeding parents should wait until at least six weeks to three months postpartum before starting GLP-1s.
- Individual Assessment: GLP-1s are an option as long as your doctor prescribes them after a thorough assessment of your individual health status. Postpartum recovery has a lot of factors, including hormonal changes, sleep deprivation and mental health, which must all be taken into account before starting a medication like this.
- Eligibility Criteria: In general, the drugs get the green light for women with a body mass index (BMI) of 30 or higher, or for those with a BMI of 25 to 29.9 with certain coexisting conditions (like high blood pressure or diabetes).
Potential Benefits of GLP-1s Postpartum
Weight loss as a result of GLP-1s, when medically appropriate, can result in health benefits like lower blood pressure, a lower risk of developing type 2 diabetes, improved sleep and, in some cases, an overall improved quality of life.
Potential Side Effects of GLP-1s
People using GLP-1s may experience nausea, vomiting and constipation. These side effects are a result of the medication’s slowing of gastric motility in the body. GLP-1s can also result in rare but serious side effects, including pancreatitis, gallbladder disease and cholecystitis. Some patients also report hair thinning, which typically occurs after prolonged use at high dosages, and may reflect nutritional deficiencies rather than a direct pharmacologic effect. Some patients also notice temporary vision changes during treatment.

Considerations for Future Pregnancies
If you're planning to try for another baby, you'll need to be off GLP-1s for one to two months before trying to conceive.
Alternatives to GLP-1s for Postpartum Weight Loss
The primary goal during the postpartum period should be to nourish your body, not restrict it. For postpartum individuals, the goal should never be about ‘bouncing back,’ but rather about restoring metabolic equilibrium, improving energy levels, and reclaiming a sense of control over appetite and physiology.
If you’d like to lose weight gradually and safely, and your healthcare provider gives you the green light, there are some extremely effective alternatives to GLP-1s.
Lifestyle Modifications:
- Staying Active: Staying active while you’re pregnant is the best way to set yourself up for successful, safe weight loss after baby arrives-but even if you weren’t working out pre-baby, postpartum exercise is still helpful in weight loss-and your health in general.
- Gradual Exercise: If you had an uncomplicated vaginal delivery, you can start light exercises, like walking and pelvic tilts, within a few days after giving birth. If you had a C-section or complications, talk to your provider before starting any exercise. Once you reach the six-week point-closer to eight weeks after a C-section-you’ll likely be able to start higher intensity workouts, such as aerobic activities and weightlifting. Just be sure to get your doctor’s okay first.
- Balanced Diet: Prioritize lean protein at every meal “to stabilize blood sugar, reduce cravings and support muscle recovery.” Favorite options include grass-fed beef, wild-caught seafood, chicken and eggs. Include fiber-rich foods, like fruits, veggies and whole grains, in your meals.
- Hormonal Changes: Postpartum is a major hormonal transition. Cortisol, the stress hormone, and insulin levels can fluctuate, sleep is disrupted and your body’s recovering from pregnancy and possibly breastfeeding-all of which can impact metabolism and hunger signals. It’s not just about calories, it’s about your body’s overall state of recovery and support.
The Importance of Medical Guidance
If you’re considering GLP-1s postpartum, it’s essential to talk to your healthcare provider. If you meet the eligibility criteria-either a BMI of 30 or higher or a BMI of 25 to 29.9 in addition to a health condition-and you’re struggling to lose weight postpartum while implementing lifestyle changes, you could be a candidate for GLP-1s.
Compounded Weight-Loss Medications
Compounded GLP-1s are “custom formulations of active ingredients like semaglutide or tirzepatide, often blended with supportive agents such as amino acids or vitamins. The same safety recommendations with name-brand GLP-1s apply to compounded versions. However, it’s important to note that compounded versions aren’t FDA-approved. The challenge with compounded products lies in the variability of manufacturing standards across compounding pharmacies, so it’s crucial that patients receive their medication from a pharmacy that is [United States Pharmacopeia]-compliant and follows rigorous sterility and potency testing protocols.
