Is Bariatric surgery safe for PCOS or PMOS patients?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I have struggled with PCOS (polycystic ovary syndrome) or PMOS (polyendocrine metabolic ovarian syndrome) and insulin resistance for years, and despite working with a nutritionist, my weight keeps going up. My doctor suggested metabolic surgery, but I am planning to conceive in the next two years.

Would bariatric surgery improve my fertility, or should I wait until after pregnancy? Additionally, I have read that some surgeries cause long-term vitamin deficiencies. Would a gastric sleeve or bypass be safer for someone with PCOS? Lastly, I do weight training. How can I maintain muscle mass after surgery?

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Polycystic ovaries and insulin resistance can be tough to manage together, along with keeping weight normal and fertility in check. Metabolic (gastric) surgeries can improve fertility, PCOS (polycystic ovary syndrome), now known as PMOS (polyendocrine metabolic ovarian syndrome), hormonal imbalance, and aid in weight reduction. There is evidence that it might cause deficiencies of certain minerals and vitamins like A, D, E, K, and B12, so it is necessary to continue taking supplements. The best time to conceive after surgery is usually 12 to 18 months.

Maintaining muscle mass after bariatric surgery, especially when engaging in weight training, can be challenging, but absolutely doable with these steps:

  • Protein intake.
  • Strength training.
  • Stay hydrated.
  • Take supplements.
  • Monitor muscle mass.

I hope this helps.

Thank you.
