Pregnancy after Weight-Loss surgery: blood sugar swings may harm baby
NCT ID NCT05084339
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at how blood sugar patterns change during pregnancy in women who have had gastric bypass or sleeve gastrectomy. Researchers want to see if these changes lead to smaller babies or other complications. They are also testing if a continuous glucose monitor (CGM) can better detect gestational diabetes in these women. The study will follow 190 pregnant women, half with prior bariatric surgery, using a blinded CGM at four points during pregnancy.
