Nutrition care in bariatric/metabolic surgery.

The dietitian is an integral part of the multidisciplinary team of bariatric and metabolic surgery. The nutritional intervention is started already in the period of preparation for the bariatric procedure and focuses on the modification of the patient's current eating habits, weight reduction and understanding of the principles of the postoperative diet. After the bariatric procedure, the nutritional intervention ensures optimal nutrition of the patient within a specific diet regime implemented in the first weeks after the operation. However, nutritional care should continue at regular intervals for a long time after the procedure. It includes, for example, control of the appropriate diet composition, adherence to portion sizes and adequate drinking regime, as well as supplementation recommendations, all in relation to weight development, body composition and laboratory results.
