Pregnancy after gastric bypass for morbid obesity.

There has been only one previous report on pregnancies following gastric bypass for the treatment of morbid obesity. In this study 57 such pregnancies were compared to a group of control pregnancies occurring in morbidly obese women before their bypass surgery. There was a significantly lower incidence of hypertension and large-for-gestational-age infants in the postoperative pregnancies. There was no significant difference in a number of other pregnancy complications studied.
