Today obesity and its related diseases are spreading like wild fire. Gastric bypass surgery or Bariatric surgery has become a solution for this hard-core problem. It is operated to treat morbid obesity. This operation removes the excess weight from the body. Obesity is the root of many severe life-shortening diseases. The operation is a great relief for those people who are suffering from obesity. Many people perform various types of physical exercises, also do dieting to lose weight, but it hardly affects them, and at last, they need to undergo the surgery. The operation is performed in some major hospitals in India. With its upcoming, the patient need not have to panic on the issue.

Obesity is a growing epidemic around the world. They operate it on those people who fail to reduce weight. An obese person suffers from hypertension, insomnia, gallbladder disease, liver disease, degenerative disc disease, heart disease, infertility, arthritis in weight bearing joints and gastroesophageal reflux disease. A gastric bypass surgery first divides the stomach into a small upper pouch and a much larger, lower "remnant" pouch and then re-arranges the small intestine to allow both pouches to stay connected to it. Gastric bypass surgery comes in many forms. Of these, laparoscopic gastric bypass surgery is more effective. The benefit of this surgery is smaller scars, lower risk of hernias, and faster recovery compared to traditional large incision gastric bypass surgery.

Drs. Mason and Ito originally pioneered bariatric surgery in the 1960's. From then, the surgery had undergone various changes. Today, gastric bypass with roux-en-y is the most commonly performed weight loss procedure and approximately 65% effective in losing target weight. Records show that those patients who had undergone the surgery fail to survive long. It is seen that the major cause of death in the weight loss patients is heart failure. The patient also suffers from depression. The change in their food habit is the major cause of depression. They face difficulty in climbing stairs or lifting heavy objects, and increased fatigue following simple physical tasks. In the past, serious obesity was interpreted to mean weighing at least 100 pounds (45 kg) more than the "ideal body weight". This criterion failed for persons of short stature.

A gastric bypass patient needs to be very careful about their diet. They require consulting a registered dietician always. If a proper diet is strictly followed, it would be very helpful for the patient. A person is not permitted to eat everything directly after the operation. There are numerous restrictions that the patients need to follow to recover soon. Liquid foods like juice, milk, cooked cereal should be taken and soft foods like fresh fruits, cooked vegetables are most preferable. They can also intake-pureed food. In an obese person the doctor need to operate complications like anastomotic leakage, anastomotic stricture, dumping syndrome etc. Today, an obese person can lead a normal life like others if he or she undergoes the gastric bypass surgery.
