Offer the Conversation
Using a GLP-1 for weight loss takes time, usually around 1 year to reach a plateau. Boots encouraged nonfertility providers to ask patients of reproductive age about their family plans as an opening.
“I hope for all primary care doctors and gynecologists, that with any patient of reproductive age, you should be bringing this up, asking, ‘Have you thought about having kids? Are you thinking about it soon?’ And if they say they are sometime in the near future, then you can say, ‘Is it OK if I bring up your weight?’ And you should ask permission.”
If the patient declines, it’s OK to bring it up again at a future visit.
“People with obesity have often experienced negative weight bias that impacts their care,” Jimenez said. “Treat obesity as a disease, not a personal failing. Ask permission to discuss weight with the patient beforehand. If they say no, respect that answer. This goes a long way in developing a positive relationship, so they return for care and may be willing to discuss later.”
When patients are open to the conversation, Boots suggests not focusing on the potential for poor outcomes, and instead perhaps saying, “If you’re thinking about having a baby in 5 years, optimizing your health now will not only make your pregnancy healthier, but your child healthier long-term.”
Discussing contraception plans remains important. People starting semaglutide or tirzepatide should use contraception other than oral birth control for 4 weeks while starting the medicine and for 4 weeks after each dose increase.
Boots said that the contraception conversation is particularly important because many people have come to deeply believe that they are infertile and, thus, may perhaps think contraception advice doesn’t apply to them. Maya hypothesized that behavioral changes following weight loss may also be a pathway toward pregnancy.
“Pregnancy while on GLP-1 RAs does happen. I always have a discussion about this possibility and contraception. This can sometimes be challenging for people with infertility to consider,” Jimenez said. “Explaining the risks, benefits, and unknowns can help. As the [Fertility and Sterility] paper describes, the limited data available has not shown increased fetal or maternal complications. We need more high quality data to better understand the impact of exposure or use around the time of conception and during pregnancy.”
It’s also important to introduce the idea to patients that they may someday need to come off the medications, such as when they are ready to have children, and how important lifestyle and behavioral changes will be at that time, Maya said.
“We do know what the alternative is, and we do know what the risks of obesity are,” she said. “So, it’s a tug and pull. We’re not starting off with healthy. We’re starting off with a disease that is physically and emotionally very difficult for the patient, especially when it starts in childhood.”
