Gastric Bypass Surgery for Weight Loss at Medical City Plano
The gastric bypass is a restrictive and malabsorptive procedure. It restricts food intake and the amount of calories and nutrients the body absorbs.
A small stomach pouch is created at the top of the stomach to restrict food intake. Then, a section of the small intestine is attached directly to the pouch. This allows food to bypass the lower stomach and a portion of the small intestine. You will feel full sooner and eat less. Bypassing a part of the small intestine means the body absorbs fewer calories. The hunger hormone Ghrelin is reduced thus decreasing the sensation of hunger. Due to the nature of this procedure it is not reversible.
