The reports of an Ozempic baby boom are anecdotal, and it’s not known how widespread the phenomenon is. Experts say significant weight loss can affect fertility. Others speculate that the GLP-1 drugs could interfere with the absorption of oral contraceptives, causing birth control failures.
The drugs also may interfere with oral contraceptives in some patients, doctors say. The GLP-1 drugs help people lose weight by slowing gastric emptying, curbing hunger and leaving people feel full sooner. It may be that the GLP-1 drugs also affect the absorption of oral contraceptives, said William Dietz, physician and chair of the STOP Obesity Alliance at the Milken Institute School of Public Health at George Washington University. “This may mean that birth control medications are metabolized or ineffective,” he said.
