The entire operation is done through several small incisions and with the use of long instruments. A small pouch, created with staples, limits how much the patient can eat and diminishes appetite. The intestine is then rerouted in such a way that a small segment does not absorb calories.
Another effect of the rerouting of the intestine is a severe reaction to the ingestion of foods high in sugar. The reaction, which includes lightheadedness, nausea, palpitations, sweating, cramping, and possible diarrhea, is the result of certain foods emptying too quickly into the intestines. It is a common side effect that acts as a deterrent, causing people to avoid foods with sugar.
In order to be eligible for laparoscopic Gastric Bypass Surgery, the patient must:
- have a Body Mass Index of 50 or less
- have at least two documented weight loss attempts in the past five years
- not have a medical condition that would make you a high risk for surgery
- not have abused drugs or alcohol in the past two years
- be able to follow medical advice
- be emotionally and socially stable for the past year
