Gastric sleeve is performed by removing approximately 80 percent of the stomach. The remaining stomach is a tubular pouch that resembles a banana.
This procedure works by several mechanisms. First, the new stomach pouch holds a considerably smaller volume than the normal stomach and helps to significantly reduce the amount of food (and thus calories) that can be consumed. The greater impact, however, seems to be the effect the surgery has on gut hormones that impact a number of factors including hunger, satiety, and blood sugar control.
Short term studies show that the sleeve is as effective as gastric bypass in terms of weight loss and improvement or remission of diabetes. There is also evidence that suggest the sleeve, similar to the gastric bypass, is effective in improving type 2 diabetes independent of the weight loss.
Life after “Gastric Sleeve” Surgery
To maintain the weight loss over time after surgery, patient must follow new eating habits and the given diet instructions. The doctor designs a diet guidance and some food Recommendations to suit the patient’s case. After surgery it is a must to modify your diet on different stages, where you start with a drinks diet then a pureed food. Then you start eating small amounts of a usual healthy foods. Therefore, less volume of food is digested by the patient than he used to do before the surgery.
