Laparoscopic Roux-en-Y Gastric Bypass: Postoperative Management and Nutritional Evaluation



Gastric bypass surgery requires ongoing patient effort and commitment to attaining and maintaining the appro priate body weight and a healthy lifestyle. Surgery helps limit the food intake, whereas patients should attempt to improve their eating habits and dietary practice. This requirement should be made clear to prospective patients and continually emphasized during pre- and postopera tive counseling. For maintaining the desired weight, patients need to learn how to make the right food selec tions and comply with all nutrient supplementations. The Roux-en-Y gastric bypass procedure involves bypassing a large part of the stomach and the duodenum, and a vari able length of the proximal jejunum. Consequently, patients are at risk for developing various deficiencies, in particular protein, iron, vitamin B12, folate, calcium, and other macro- and micronutrients. With proper supple mentation these deficiencies are largely avoidable.
