Gastric bypass is a surgical procedure that achieves weight loss by two mechanisms, first building a stomach of a very low capacity (20-50cc), and on the other hand, takes place a cross in the small intestine (bypass ) that determines which is used only about 60% for the digestion and absorption of food.
This procedure is a restrictive and a malabsorptive component, so it is considered a mixed technique of bariatric surgery.

This surgery is malabsorptive and has two components.
First, itbuilds a vertical gastrectomy with resection of approximately 80% of the stomach.
Secondly there is a crossing in the small intestineduodenum height advantage to be approximately 50% of it for digestion and absorption of food.

A surgical procedure that involves removing approximately 80% of the volume of the stomach.
It leaves a tube shaped stomach that represents approximately 150-200cc capacity.
Weight loss is achieved important reductions taking place in the volume of the stomach, so it is considered a restrictive surgery

Gastric Bypass procedures are currently considered an elective procedure with no universally accepted algorithm to decide who should have the surgery.
In the diabetic patient, certain types result in 99-100% prevention of insulin resistance and 80-90% clinical resolution or remission of type 2 diabetes.
