ROUX-EN-Y GASTRIC BYPASS
Gastric bypass is the most common weight loss procedure performed in the United States and provides very effective, consistent and prolonged weight loss. The procedure creates a small stomach pouch which causes restriction in food intake. The smaller pouch allows the patient to feel “full” sooner.
The second part of the procedure creates a “bypass” of the first and second portions of the small intestine. This combination of gastric restriction and intestional bypass allows decreased absorbtion of calories into the body. The bypassed portion of the stomach is not removed but is stapled shut and as a result is unable to accept food which is consumed. This operation results in delaying the mixing of food with digestive enzymes such as bile, pancreatic secretions and stomach acids. The absorption of calories is reduced and there is an increased sense of fullness and satisfaction. Most patients describe a decreased desire to eat and decreased sense of hunger. This results in the improved ability to control and sustain weight loss.
The average patient may expect to lose two thirds of their excess weight within two years. More than 90% of patients will maintain successful weight loss even five years after surgery. In addition, certain obesity-related conditions such as sleep apnea, high blood pressure, diabetes and degenerative joint disease have been reported to significantly improve or resolve up to 95% of the time.
