Sleeve Gastrectomy

Sleeve Gastrectomy is also known as Gastric Sleeve In the surgical procedure, a large portion of the stomach (approximately 80%) is removed with intent to reduce the gastric volume. Since the food intake is limited with the stomach reduction, the patient loses weight. The stomach that normally looks like a sac will take the shape of a thin and long sleeve after this procedure. The surgically removed part of the stomach is taken out of the body, in an irrevocable way. This surgically removed part of the stomach includes the part producing ghrelin, i.e. the hunger hormone that stimulates the hypothalamus region of the brain. In this way, the patient’s feeling of hunger will decrease but will not be lost completely. In sleeve gastrectomy operations, the stomach valves called the ‘pyloric valves’, which regulate the emptying of the stomach, are preserved. Since these valves are preserved, there will be no change in the digestive system. However, you will experience the feeling of satiety more quickly, by eating less amount of food. People who have undergone sleeve gastrectomy can reach the feeling of fullness by eating less than normal, thanks to their reduced stomach. Sleeve gastrectomy surgery is intended to enable the person to lose weight by eating less and consuming healthier foods. Sleeve gastrectomy can be performed with both open and closed methods.
