5 Reasons Of Weight Gain After Gastric Bypass Surgery


A lot of patients tend to regain some degree of weight after a few years of gastric bypass surgery. The amount of weight gained varies from patient to patient. Obesity is a chronic progressive disease and some degree of weight regain is expected and happens with almost all patients. However, in some cases significant amount of weight may come back and there can be various reasons for that. These could be related to the surgery or may be related to a patient’s lifestyle. Some of the reasons are listed as under:

  1. Gradual and progressive dilatation or enlargement of the stomach pouch or the stomach (the opening created by joining the stomach pouch to the small intestine) leads to increase in the amount of food intake. If attention is not paid to the quality of food and calories being consumed, there are chances of weight regain.
  2. It is important to follow a healthy diet and lifestyle post gastric bypass surgery. This is not a miracle surgery and failure to do this may lead to weight regain after a few years of surgery. Lifestyle modification must be followed lifelong.
  3. Alcohol intake even in the smallest quantity is strictly a ‘No’ post surgery as it provides empty calories and is a big cause for weight regain after gastric bypass surgery.
  4. Post surgery depression or any other psychological illness may also contribute to weight gain. Some anti-psychiatric medications also lead to weight gain.
  5. Patients on medications like steroids or immune-suppressants may also regain weight.
