How is Gastric Bypass performed?
Gastric bypass surgery, also known as Roux-en-Y gastric bypass, is a type of weight-loss surgery that involves both restrictive and malabsorptive components to help individuals achieve significant weight loss. This surgical procedure is often recommended for people with severe obesity who have not achieved success with other weight-loss methods.
Restrictive Component
- A small stomach pouch is created at the top of the stomach using staples or a vertical band.
- This smaller stomach pouch restricts the amount of food that can be consumed during a meal, leading to a feeling of fullness with smaller amounts of food.
Malabsorptive Component
- The small intestine is divided, and the lower portion is connected directly to the newly created stomach pouch.
- The upper portion of the divided small intestine is then reconnected to the lower portion further down, creating a “Y” shape.
- This rerouting of the small intestine limits the absorption of calories and nutrients, leading to malabsorption.
The combination of the smaller stomach pouch and the rerouted small intestine results in reduced food intake and decreased absorption of calories and nutrients. This dual mechanism contributes to significant weight loss. Gastric bypass surgery is performed using a laparoscopic approach, involving small incisions and the use of a camera and specialized instruments. This minimally invasive technique often results in a faster recovery compared to traditional open surgery add period at the end.
