Gastric Bypass Surgery
What is it?
Gastric bypass surgery is more complicated than sleeve gastrectomy or insertion of laparoscopic adjustable gastric band. It involves surgery to reduce the size of your stomach (smaller meals) and re-route or bypass part of your small bowel so you don’t absorb as much food (malabsorption component)
The first component involves dividing the proximal stomach from the rest of the stomach. Following this the proximal part of the small intestine is divided and connected to the newly created stomach pouch. The final part is to connect the top portion of the divided small intestine to the small intestine further down.
The most common gastric bypass surgery is the roux-en-y gastric bypass surgery as described.
This procedure has slightly increased risks of complications.
