In pregnant women post WLS, higher than normal doses of vitamins and some minerals, are both safe and necessary to ensure a healthy pregnancy. In fact, data would suggest that these women are particularly at risk of nutritional deficiencies, leading to maternal anaemia, neural tube defects, microphthalmia, Wernicke’s encephalopathy and foetal cerebral haemorrhage1, 6. Adequate nutritional assessment and supplementation, as well as monitoring of nutritional markers during pregnancy, is therefore essential to prevent adverse pregnancy outcomes1, 6. Finally, the American Society of Metabolic and Bariatric Surgery (ASMBS) recommends that optimizing postoperative outcomes and nutritional status, begins with preoperative screening15.
