Weight loss surgeries are becoming extremely popular nowadays for guaranteed weight loss. Restriction operations are one such option which is most often used for weight loss. Under this form of surgery all our food intake is restricted by creating a small pouch at the top of the stomach where the food enters from the esophagus. Due to the small size of the outlet, the process of emptying of food is delayed from the pouch and causes a feeling of fullness. This process makes us eat less thus helping in the weight loss process.

Restriction operations are normally of two types - gastric banding and vertical banded gastroplasty. Both the types of operations serve only to restrict food intake without interfering our normal digestive process.

In the procedure of gastric banding, a band made of special material is placed around the stomach near its upper end, creating a small pouch and a narrow passage into the larger remainder of the stomach. According to researchers, it might be possible in the near future to perform gastric banding with smaller incisions through a laparoscope. A laparoscope refers to a flexible fiber optic tube and light source through which some surgical instruments may be passed. Laparoscopic gastric banding has not been approved by the Food and Drug Administration so far.

The procedure of Vertical banded gastroplasty is the most common and frequently used restrictive operation for weight control. Under this procedure, both a band and staples are used to create a small stomach pouch for restriction of our food intake. The best part about restrictive operations is that it leads to weight loss in almost all patients. However, weight regain does occur in some patients. Still, some patients are unable to adjust their eating habits and fail to lose the desired weight as in all weight-loss operations, successful results depends on the motivation of the person opting for it.
