Specialized care for women pregnant after bariatric surgery.

Growing numbers of women today will seek bariatric surgery before pregnancy. Protein-calorie malnutrition; hyperemesis; intestinal hernias; dumping syndrome; anemia; and deficiencies in calcium, folic acid, and vitamins B12, D, and K are all possible complications that can impact pregnancy. This article reviews the nutritional and pregnancy-related consequences of current surgical procedures and summarizes existing research showing positive and negative effects of weight-loss surgery on pregnancy outcomes. Practice-based clinical recommendations will help guide clinicians caring for the increasing number of women who become pregnant after having bariatric surgery.
