Gastric Bypass Surgery

Gastric bypass surgery uses a combination of restriction and malabsorption to achieve results. During the procedure, the surgeon creates a smaller stomach pouch. The surgeon then attaches a Y-shaped section of the small intestine directly to the pouch. This allows food to bypass a large portion of the small intestine, which absorbs calories and nutrients. Having the smaller stomach pouch causes patients to feel fuller sooner and eat less food; bypassing a portion of the small intestine means the patient's body absorbs fewer calories.

Gastric bypass surgery can be performed laproscopically or robotically. Both methods are minimally invasive and result in less pain and a shorter recovery time for the patient. The patient also experiences less blood loss and less scarring than the patient who undergoes traditional open gastric bypass surgery. In clinical trials, gastric bypass surgery has been found to resolve type-2 diabetes, to lower high blood pressure and to lower high cholesterol in the majority of patients. Many patients also experience an improved quality of life. There are also concerns associated with surgery, including risk of dumping syndrome and the need for dietary supplements. The stomach, duodenum, and parts of the small intestine cannot be seen easily using x-ray or endoscopy if there are problems after surgery such as ulcers, bleeding, or malignancy.
