Pregnancy after bariatric surgery: the effect of time-to-conception on pregnancy outcomes.

Background: At our medical center, female patients who have undergone bariatric surgery are advised to defer pregnancy for 2 years after surgery to avoid the following complications and their potential consequences for the fetus: inadequate gestational weight gain, inadequate postsurgical weight loss, hyperemesis gravidarum, nutritional deficiencies, gestational diabetes, and gestational hypertension.

Objectives: To examine the effect of time from surgery to conception on pregnancy course and outcomes in bariatric patients.

Setting: University.
