Nutrition sessions are provided by Texas Surgical Services before surgery, 2 weeks after surgery, 6 months after surgery and yearly or as often as the patient desires. Metabolic testing is also available for nutrition evaluation to tailor a nutritional plan just for you. Patients must be committed to making the diet and exercise changes necessary to maintain their weight loss results. Patients will meet with a nutritionist before and after surgery to help them make healthy and educated food choices and adopt new eating habits. Since the stomach is much smaller in size after bariatric surgery, the amount of food a patient can consume is very limited. Certain types of foods that were tolerated easily before surgery may now cause discomfort. Therefore, it is important for patients to carefully follow the recommended guidelines after gastric surgery.
