Obesity surgery

Surgery to treat obesity is performed only in severe cases. This surgery is done when diet control or exercise can not cure the obesity. It is performed on the stomach or the intestine. People or who are severely obese and have tried all the other methods to reduce weight are the appropriate candidates for obesity surgery. The paramount goal of this surgery is to reduce food intake which in the long run reduces weight. Some types of surgery interrupt food digestion and absorption. This prevents vitamins and calories from being absorbed hence weight gain is reduced.
Normally the food we eat passes through the digestive tract and the digestive juices and enzymes that are available help in absorbing the calories and other nutrients. When foods get to the stomach, strong acids aid the digestion process. The food passes through the small intestine, and it is further digested by bile and other pancreatic juices. Food particles that are digested by the small intestine are moved to the large intestine and are eliminated after that. When obesity surgery is performed, the food intake is restricted. In addition to the surgery, the patient is provided with a food and exercise routine that he/she must adhere to for life. Below are some different ways in which surgery is performed:

Using a bracelet type bandsurgery

This kind of obesity surgery is done by placing a small bracelet type band around the top of the stomach. The size of the opening is controlled using a circular balloon in the band. Inflation and deflation of the balloon is done using a saline solution according to the patient’s requirements. This usually reduces the food intake and hence encourages weight loss.

Pouch method

This surgery is done by creating a tiny pouch similar to the one above and food is administered directly from the pouch to the small intestine. The stomach, duodenum, and upper intestine are not in contact with food anymore. This way the manner in which the intestine absorbs food is altered.

Part of the stomach removal

In this method of obesity surgery, some part of the stomach is removed. This makes the patient feel full faster and eat less. The food is redirected so that a significant proportion of the small intestine is skipped. Results are experienced quickly when this method is used.

Removing most of the stomach

surgeryThis method of obesity surgery involves the removal of most of the stomach. This substantially lessens the generation of the hormone that prompts appetite. You must keep in mind that these changes are for life. Know that once you have chosen this surgery, you will have to go through a lifetime commitment in matters of food, nutrition, exercise and your entire lifestyle change.
