SLEEVE GASTRECTOMY
It is one of the most commonly done procedures. It is a surgical weight-loss procedure in which the stomach is reduced to about 25% of its original size, by surgical removal of a large portion of the stomach, namely the body and funds of the stomach. So the stomach shaped like a bag will be a mere tube with a small pouch thereby restricting the quantity of food intake. The procedure permanently reduces the size of the stomach. The procedure is performed laparoscopically and is not reversible.
- 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.
