SLEEVE GASTRECTOMY
Sleeve Gastrectomy is an irreversible procedure that curtails the size of the stomach, this operation surgically removes two-thirds of the left side of the stomach. This results in a new stomach which is roughly the size and shape of a banana and looks like a sleeve or a tube. Among the bariatric procedures, sleeve gastrectomy is the most commonly performed procedure.
Sleeve gastrectomy is a restrictive form of weight loss surgery that limits the capacity of the stomach to 60 cc – 150 cc. Unlike other forms of bariatric surgery, the outlet valve and the nerves to the stomach remain intact. This procedure also eliminates the hunger inducing hormone called ‘Ghrelin’, hence patient feels full after consuming small amounts of food, and lose weight quickly.
- Reducing the capacity to eat/avoid over-eating because of the reduced volume of stomach
- Reducing the appetite (by removing the fundus of the stomach producing the hormone Ghrelin)
- Reducing the absorption of food in taken (by increasing the gastric emptying time and intestinal transit time)
- Increasing the energy expenditure rate (by increasing the levels of hormone Oxyntomodulin produced in the ileum)
Most patients can expect to lose 60-70% of their excess body weight over a12 months period with the sleeve gastrectomy alone. In addition, the improvements in associated diabetes, hypertension, dyslipidemia, menstrual irregularities, etc also improves significantly.
