Gastric Bypass
Gastric bypass is a mixed procedure with two mechanisms of action: The first consists of creating a smaller stomach pouch (capacity of 1-2 oz.), causing restriction after eating a small amount of food.
The second mechanism is to decrease the absorption of calories and nutrients, bypassing a part of the food into the intestine. This triggers hormonal changes that help in weight loss and improving metabolic diseases.
