A recent study conducted by the research team at SGF and presented at the 2024 ASRM Congress and Expo has provided some reassuring news about weight changes during egg retrieval cycles for patients undergoing IVF or egg freezing.
“Setting accurate expectations is key,” says Cassandra Roeca, M.D., SGF Colorado reproductive endocrinologist and research contributor. “This study allows us to give patients clear, data-backed information about what to expect, helping them feel more in control. By understanding what factors contribute to weight changes, we can offer more personalized care and ensure that our patients are well-supported throughout their treatment.”
Will I gain weight during fertility treatment?
The research looked at over 22,000 cycles of ovarian stimulation, examining how patients’ weight fluctuated before and after an egg retrieval. On average, patients gained about 1.4 pounds, but this varied quite a bit, with some losing up to 5 pounds and others gaining as much as 15 pounds.
Certain factors were linked to a higher likelihood of weight gain including having a lower initial body mass index (BMI) and retrieving a larger number of eggs. The study also found that patients who developed ovarian hyperstimulation syndrome (OHSS) tended to gain more weight and took longer to return to their normal weight.
The retrospective cohort study, Evaluation of Mean Changes in Weight During and After Ovarian Stimulation, was presented at this year’s ASRM Scientific Congress & Expo. Learn more about ASRM 2024.
How long will it take for my body to go back to normal after fertility treatment?
The good news is that this weight gain is usually temporary, and most patients return to their normal weight within two weeks of egg retrieval. “We hope this new research gives patients peace of mind,” adds Dr. Roeca. “Knowing that any weight gain during treatment is typically modest and temporary can help reduce stress and improve your overall experience.”
By understanding what might happen to your body during an egg retrieval cycle, you can better plan ahead and stay in control of your health.
Tips for managing weight during ovarian stimulation
While the study shows that weight changes are usually minor and temporary, it’s natural to want to feel your best during fertility treatments. Here are a few tips to help manage any weight fluctuations:
- Stay hydrated Drinking enough water helps reduce bloating and keeps your body functioning optimally during treatment.
- Eat balanced meals Focus on whole foods like fruits, vegetables, lean proteins, and healthy fats, which can help you feel energized and maintain a steady weight.
- Gentle movement Light exercise, like walking or cycling, can improve circulation and help with any discomfort or bloating.
- Talk to your doctor If you’re concerned about weight changes or feel uncomfortable, don’t hesitate to bring it up during your appointments. Your care team can provide personalized advice.
Take the next step
Fertility treatments can be an emotional and physical rollercoaster but having the right information can make all the difference. If you’re concerned about how your body might change during ovarian stimulation, this study offers reassuring news: any weight changes are usually minor and short-lived, helping you focus on what really matters — your path to parenthood.
