Morbidly obese women may often have problems with fertility and the ability to become pregnant. Obesity may also increase the risk of complications during pregnancy. Pregnancy is not advised during the first year when the most rapid weight loss is occurring as it may deprive the fetus of essential nutrients that it needs to grow. Because weight loss may improve fertility, it is imperative that a reliable form of birth control be used following surgery. Women who are contemplating bariatric surgery and future pregnancy should discuss this with their obstetrician/gynecologist.
