The gastric band:
A changeable diameter ring is placed on the upper part of the stomach.
Thereby reducing the food bowl, the feeling of fullness faster.
The bypass:
It sends a short circuit of a portion of the stomach so that a head portion of the food directly into the small intestine and are thus treated in smaller quantities.
The gastrectomy is a technique of intermediate, as a first step, to remove a portion of the stomach (sleeve), especially one containing cells which secrete ghrelin hormone appetite. Thus, in addition to a decrease in appetite, the food arrives more quickly in the intestine. Then, in a second time, it is possible to make a bypass.

Health side, the operation proves clearly beneficial as recently demonstrated by a Swedish study called SOS Study, published in the renowned Journal of the American Medical Association (Jama).

For fifteen years, more than 2,000 obese people carried were compared to many non-operated obese subjects.

Regardless of the surgical technique used and whatever the body mass index before the operation, the surgery has significantly improved the quality of life and increased hope in reducing mortality.

People carried were less likely to die from heart attack, stroke, but also of cancer. The operation also reduces the incidence of complications, including type 2 diabetes.
