With gastric bypass surgery a small stomach pouch is created. Next, a Y-shaped section of the small intestine is attached to the pouch to allow food to bypass the lower stomach
With gastric bypass surgery the stomach is divided into a small upper part and a much larger lower part. Next, a section of the small intestine is attached to the small pouch to to allow food to enter directly into the small bowel, thus bypassing most of the stomach and about one third of the small bowel. Food is therefore not absorbed from this bypassed section.
The procedure is mostly carried out laparoscopically.
This gastric surgery reduces the absorption of nutrients and so reduces the calorie intake leading to weight loss.
Good weight loss results can be achieved however this procedure is not reversible and long term nutritional/mineral supplements are required in order to avoid anaemia and vitamin deficiencies that may lead to bone density problems in the future.
