Regaining weight after sleeve gastrectomy
Sleeve gastrectomy is a type of bariatric surgery with a high success in weight loss. The goal is to lose at least 75% of the excess weight. Success rates reach up to 100% in patients who fully follow the nutritional recommendations and maintain a healthy and active life after surgery. Because sleeve gastrectomy is a restrictive bariatric surgery, it does not cause malabsorption. While this can be considered as an advantage because it does not require long-term use of vitamins, it may pose a danger to some patients in terms of regaining weight, especially after the 2nd year of surgery. Especially those who eat frequently and maintain high-calorie liquid diet may regain 10-15% of the weight they lost. Regaining weight rates after sleeve gastrectomy are about 20%. In short, one out of every five people who have sleeve gastrectomy may regain 5-10 kilos of the weight they lost in the long term.
Even though there is weight gain after sleeve gastrectomy, patient does not regain their previous weight before surgery and it is relatively rare to reach the previous weight. Weight regain is not just a problem specific to sleeve gastrectomy. After malabsorptive gastric bypass surgeries, weight gain may be seen at varying rates. In this regard, what determines the success of weight loss or regaining weight is not the type of surgery, but how well the patient can change his life after the surgery.
