Gastric Bypass Operation

In this procedure, stapling creates a small (15 to 20cc) stomach pouch. The remainder of the stomach is not removed, but is completely stapled shut and divided from the stomach pouch. The outlet from this newly formed pouch empties directly into the lower portion of the jejunum, thus bypassing calorie absorption. This is done by dividing the small intestine just beyond the duodenum for the purpose of bringing it up and constructing a connection with newly formed stomach pouch.


  •   One year after surgery, weight loss can average 77% of excess body weight.
  •   After 10 to 14 years, 50-60% of excess body weight loss has been maintained by some patients
  •   Upto 96% of certain associated health conditions improve or resolve

Risks & Side effect

  •   Staple line leak/bleed/ intestinal obstruction
  •   Deficiency of iron and calcium, Vit B 12. All of the deficiencies mentioned above, however, can be managed through proper diet and vitamin supplements.
  •   A condition known as "dumping syndrome" can occur as the result of rapid emptying of stomach contents into the small intestine. This is sometimes triggered when too much sugar or large amounts of food are consumed. While generally not considered to be a serious risk to your health, the results can be extremely unpleasant and can include nausea, weakness, sweating, faintness and, on occasion, diarrhea after eating. So its advised to eat only small portion, chew well and eat slowly, never eat & drink at same time.
  •   Risk to life: 0-0.5%
