AMAYA GARCIA, M.ª J. et al. Micronutrients in bariatric surgery. Nutr. Hosp. [online]. 2012, vol.27, n.2, pp.349-361. ISSN 1699-5198.

The morbid obesity is a chronic disease with increasing prevalence and that associates an important morbility and mortality. The bariatric surgery is the most effective treatment to secure a weight reduction maintained in the time and a diminution in the rates of complications associated to the obesity. The overweight and the obesity are risk factors for the deficit of several micronutrients like vitamins B1, B6, C, folic acid and D, minerals like the iron and trace elements like zinc, generally by dietetic deficit. In spite of it, at the moment a consensus don´t exist about the monitoring of micronutrients in the preoperative one, although it seems reasonable in view of his considerable prevalence. The bariatric surgery can bring about deficit of micronutrients or to intensify previous deficiencies, as much by limitation of the ingestion like by the maldigestión and malabsorption in the malabsortives techniques, being the parallel risk to the ponderal loss. It is precise to monitor of by life the different micronutrients, mainly after the malabsortives surgical techniques. The use of a polivitamínic complex of systematic form is recommended and in the cases in which he is insufficient, it will be precise to use specific suplementación.
