title: Vitamin a deficiency in pregnancy: perspectives after bariatric surgery.
abstract: This study aims to describe the clinical consequences of vitamin A deficiency (VAD) in pregnant women after bariatric surgery. Included are studies on VAD during pregnancy and after bariatric surgery conducted in humans from 1993 to 2011. There are few investigations on the relationship between pregnancy and bariatric surgery and on the damage to the binomial mother-child resulting from VAD in this relationship. The high percentage of VAD in the postoperative period is a cause for concern, especially considering the function of this vitamin in certain biological moments and in moments of intense nutritional demand. This vitamin serum evaluation is recommended during the prenatal period.
