Wegovy, Birth Control, and an Unexpected Pregnancy: Claudia’s Story
Claudia, a 27-year-old newlywed, had a plan: lose weight, then start a family. After gaining 30 pounds during COVID, she was determined to get back to her pre-pandemic weight before even thinking about pregnancy. With the help of Wegovy (semaglutide), a dietitian, and a personal trainer, she was well on her way—until she found out she was pregnant.
How Did This Happen?
Claudia had been taking birth control pills faithfully, but what she didn’t know was that semaglutide can reduce their effectiveness. Here’s why:
• Weight loss can improve fertility, making pregnancy more likely.
• Semaglutide slows digestion, reducing how well birth control pills are absorbed.
• Nausea and vomiting, a common side effect of Wegovy, can prevent birth control from working if the pill is thrown up.
Was the Baby Safe?
Claudia’s biggest concern was whether Wegovy could harm her baby. While animal studies raised concerns about birth defects, real-world data from over 50,000 pregnancies suggested no increased risk. Doctors advised her to stop taking Wegovy, and she switched to metformin, a pregnancy-safe medication that can help with weight management.
What Happened Next?
Without Wegovy, Claudia struggled to maintain her weight loss and fell into the classic “eating for two” mindset, ultimately gaining 50 pounds during pregnancy. After giving birth, she briefly attempted breastfeeding but soon restarted Wegovy, this time pairing it with a Mediterranean diet and regular gym sessions. The result? She successfully lost the weight and has maintained it for over a year—while enjoying life as a new mom to a happy, healthy baby.
The Takeaway for Young Women
If you’re using medications like Wegovy and also taking birth control, talk to your doctor about potential interactions. Weight loss can impact fertility more than you might expect, and planning ahead can help avoid surprises.
