Laparoscopic Sleeve Gastrectomy (LSG)
Laparoscopic Sleeve Gastrectomy (LSG) is one of the most popular and commonly performed bariatric procedureat our center. It is an irreversible procedure in which a small banana shaped stomach is created by surgically removing two thirds of it. Since the procedure reduces the stomach size and also eliminates ‘ghrelin’, the hunger inducing hormone, you will feel satiated with smaller portions of food and start losing weigh quickly without developing any kind of weakness.

HOW SLEEVE GASTRECTOMY SURGERY WORKS?
Sleeve Gastrectomy Surgery is a restrictive procedure. In this, about 80 % of the stomach is removed so that it takes the shape of a sleeve or a banana. This greatly reduces the size of the stomach and limits the amount of food that can be eaten at one time.
Surgery for weight loss is caused by two mechanisms – First is restriction because of a smaller stomach size and secondly removing the part of the stomach that produces the “hunger hormone” (ghrelin) contributes to the weight loss by reducing the appetite.
Sleeve Gastrectomy Surgery also results in alteration of several gastro intestinal hormone levels in the body resulting in resetting of the set point of food storage to a lower level. These hormonal changes include reduced Ghrelin, increased GLP-1, Peptide YY and Amylin, resulting in reduced appetite and increased energy expenditure.
It is fairly a simple procedure that takes about 60-90 minutes to perform and requires 3 to 4 nights stay in the hospital.
