Nutritional deficiencies before and after bariatric surgery
Maria Paula Carlini
Clínica Dr. Giorgio Baretta-Cirurgia Bariatrica, Brazil
The obesity per se can be the cause of numerous nutritional deficiencies. In nutritional assessment, in the preoperative
period the deficiencies of vitamins C, B12 and D are common and occur in up to 90% of patients. Bariatric surgery in
their technical variants provides weight loss and improves the quality of life of the patients. The restrictive, mal-absorptive
and hormonal components promote weight control over time. There is absolute need for change in lifestyle, food quality,
frequent physical activity and use of nutritional supplements permanently. Nutritional deficiencies after bariatric surgery are
common and must be monitored by a multidisciplinary team. The most important shortcomings are: Vitamin B, fat-soluble
vitamins, iron, calcium, zinc and protein. Anemia is common complication and should be treated individually; it could be due
to iron deficiency, megaloblastic anemia and pernicious anemia. Nutritional needs vary according to gender. According to the
guidelines, there is no need to use a daily multivitamin as that reaches at least 2/3 of all optimal micronutrient for an adult.
Minerals like iron can be supplied with iron 27 mg in the form of fumarate and in women of reproductive age can take up to
100 mg daily iron; calcium with 1500 to 2400 mg/day. Vitamins like Folic acids can be taken up to 240 mcg per day. Whereas
vitamin B12, daily requirement is 350 to 500 mcg orally, vitamin A daily requirement is 10.000 UI and vitamin D is 2000 UI per
day. Therefore, all operated patients need to maintain a specialized nutritional monitoring to prevent and treat these possible
nutritional deficiencies.
