31 Laparoscopic Gastric Bypass: Nutritional Management After Surgery

  • Chapter
  • First Online:
Minimally Invasive Bariatric Surgery

Abstract

Patients who chose to have Roux-en-Y gastric bypass (RYGB) surgery need to be able to make long-term lifestyle changes and commit to lifelong vitamin and mineral supplementation. Because the amount of food that can be eaten is limited and nutrients are not fully absorbed, patients are at risk for developing a variety of macro- and micronutrient deficiencies. Nutrition guidelines should be explained at the onset of surgery consideration and reiterated at every phase of the process. This chapter will outline postoperative nutrition and supplementation requirements as well as review possible nutrient deficiencies, symptoms, and treatment for deficiencies should they occur. In addition, this chapter will address postoperative nutrition evaluation and follow-up protocols. It is important to provide continuous monitoring and adequate support to patients after surgery to ensure that they understand and are following program guidelines in order to achieve maximal weight loss and acquire skills to maintain a healthy weight.
