Gastric Bypass in India

What is Gastric Bypass ?

Gastric bypass surgery refers to a surgical procedure in which the stomach is divided into a small upper pouch and a much larger lower "remnant" pouch and then the small intestine is rearranged to connect to both. Surgeons have developed several different ways to reconnect the intestine, thus leading to several different gastric bypass (GBP) procedures. Any GBP leads to a marked reduction in the functional volume of the stomach, accompanied by an altered physiological and physical response to food.

Adjustable gastric band surgery is an example of bariatric surgery designed for obese patients with a body mass index (BMI) of 40 or greater — or between 35 and 40 in cases of patients with certain comorbidities that are known to improve with weight loss, such as sleep apnea, diabetes, osteoarthritis, GERD, Hypertension (high blood pressure), or metabolic syndrome, among others.


Gastric bypass is indicated for the surgical treatment of morbid obesity, a diagnosis which is made when the patient is seriously obese, has been unable to achieve satisfactory and sustained weight loss by dietary efforts, and suffers from comorbid conditions which are either life-threatening or a serious impairment to the quality of life.

Surgical Techniques

In general, gastric banding is indicated for people for whom all of the following apply:

  • Body Mass Index above 40, or those who are 100 pounds (7 stone/45 kilograms) or more over their estimated ideal weight, according to the National Institutes of Health,or those between 30 to 40 with co-morbidities that may improve with weight loss (type 2 diabetes, hypertension, high cholesterol, non-alcoholic fatty liver disease and obstructive sleep apnea.)
  • Age between 18 and 55 years (although there are doctors who will work outside these ages, some as young as 12.
  • Failure of medically supervised dietary therapy (for about 6 months).
  • Gastric Bypass

    Benefits of Gastric Bypass
  • Lower mortality rate: only 1 in 1000 versus 1 in 250 for Roux-en-Y gastric bypass surgery.
  • No cutting or stapling of the stomach.
  • Short hospital stay.
  • Quick recovery.
  • Adjustable without additional surgery.
  • No malabsorption issues (because no intestines are bypassed).
  • Fewer life-threatening complications (see complications table for details).
  • Potential complications

    A commonly reported occurrence for banded patients is regurgitation of non-acidic swallowed food from the upper pouch, commonly known as Productive Burping (PBing).Productive Burping is not to be considered normal.
