Weight Reduction Before Conception: Enhancing Fertility and Reducing Pregnancy Complications in Overweight and Obese Women

MedXY Editorial Team•Oct 4, 2025•news

Preconception weight loss of 10%-25% modestly increases pregnancy rates (~5% over 3 years) among overweight and obese women.
Weight loss prior to conception is associated with significant reductions in gestational diabetes, pregnancy-induced hypertension, and emergency cesarean delivery.
Lifestyle interventions, including diet and exercise, and in select cases weight-loss medications, are important tools to improve reproductive outcomes; however, timing and cessation before conception should be carefully managed.
Bariatric surgery shows promise in improving spontaneous ovulation and fertility in obesity-related anovulatory infertility, such as polycystic ovary syndrome.
