GLP-1 Medications: What Women Should Know

GLP-1 medications — semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound) — are everywhere right now. Here's the actual mechanism, and the parts of this conversation that are specific to women's health.

Last updated August 2026

How they actually work

GLP-1 receptor agonists mimic a gut hormone that regulates blood sugar and appetite, slowing digestion and increasing satiety. Originally developed for type 2 diabetes, they're now widely used for weight management given their consistent, substantial effect.

Relevance to PMOS

Insulin resistance is central to PMOS (formerly PCOS) for many patients, and GLP-1s are increasingly used off-label — or as part of a broader plan — to improve insulin sensitivity, ovulation, and metabolic markers. Worth discussing if PMOS is your actual reason for interest, not just weight on its own.

Fertility and pregnancy: the part that gets skipped

GLP-1s aren't recommended during pregnancy, and current guidance is to stop at least 1–2 months before trying to conceive — exact timing varies by drug, so ask your prescriber directly. Interestingly, some patients on GLP-1s for PMOS see ovulation return unexpectedly, which matters if you're not trying to conceive and are relying on a method that assumes irregular ovulation.

What's still uncertain

Long-term data is still accumulating, since these drugs are relatively new at this scale of use. Common side effects (GI symptoms) are well documented, but questions like long-term muscle mass loss and what happens after stopping are active areas of research — not settled science yet, which is worth keeping in mind whatever you read elsewhere.

Worth discussing with your provider
