[Nutritional deficiencies in bariatric surgery patients: prevention, diagnosis and treatment].
The number of people suffering from surgery and obesity in the western world is constantly growing. In 1997 the World Health Organization (WHO) defined obesity as a plague and one of greatest public health hazards of our time. The National Institution of Health (NIH) declared that surgery is the only long-term solution for obesity. Today there are four different types of bariatric surgery. Each variation has different implications on the nutritional status of bariatric surgery patients. Bariatric surgery candidates are at risk of developing vitamin and mineral nutritional deficiencies in the post-operative stage, due to vomiting, decrease in food intake, food intolerance, diminution of gastric secretions and bypass of absorption area. It is easier and more efficient to treat nutritional deficiencies in the preoperative stage. Therefore, preoperative detection and correction are crucial. Blood tests before surgery to detect and treat nutritional deficiencies are crucial. In the postoperative period, blood tests should be conducted every 3 months in the first year after operation, every six months in the second year and annually thereafter. Multivitamin is recommended to prevent nutritional deficiencies in all bariatric surgery patients. Furthermore, iron, calcium, Vitamin D and B12 are additionally recommended for Roux-en-Y Gastric Bypass patients. Patients with Biliopancreatic diversion and Duodenal Switch should also take fat soluble vitamins.
