Gastric Bypass Surgery
Gastric Bypass is one of the oldest surgery procedures for effective weight loss. It has been around for at least fifty years. Because of this, gastric bypass is the most extensively researched bariatric surgery. Today it is primarily used for patients who suffer from severe, morbid obesity. This surgery is not reversible because it involves cutting and stapling of the stomach and small intestines.
During gastric bypass surgery, small incisions are made in the abdomen. The stomach’s total capacity is surgically reduced to nearly the size of an egg. This alters the way nutrients are absorbed and contributes to significant weight loss. It involves the rerouting of the intestinal tract. Most of the stomach and parts of the upper intestines are now effectively bypassed. Because of this the food no longer mixes with digestive enzymes and therefore cannot be absorbed into the bloodstream. Fewer calories are absorbed by the body, and thus, weight loss occurs.
