Various surgeries that help in weight loss


Obesity is as a result of being overweight. There are various ways of losing weight that one can use to achieve their desired healthy weight. Among the surgeries one can undergo, bariatric surgery will help one in losing weight hence lowering the many risks of health problems which are as a result of being overweight. The surgery works by restriction and malabsorption.

By restriction, it means that the surgery is done to limit how much food the stomach can hold hence one eats very few calories. By malabsorption, the surgery shortens the small intestines hence reduces the calories absorbed by the body. Here are the various surgeries that help in weight loss.

Roux-en-Y gastric bypass

It will be the only part that will be receiving the food which helps in limiting the food one can eat or drink at a time. The food is then directed to the small intestine at the lower part of the main stomach. The other part of the small intestine is reattached to the main stomach to allow the digestive juices flow to the small intestine. Because of this process, the food only passes through a smaller portion of the intestine making fewer calories to be absorbed.

Gastric banding through laparoscopic surgery

This surgery involves placement of a band having a balloon placed on the upper stomach parts. Doing this is meant to create a smaller stomach pouch that is above the band having a narrow opening to the stomach. A port is then placed under the abdomen’s skin to connect to the band. Injection or removal of fluid via the port makes the balloon be inflated or deflated. The banding is meant to restrict the amount of food the stomach will be able to hold.

Sleeve gastrectomy

Here, some stomach parts are separated and removed from the body. These parts that remain are then made into a structure that looks like a tube. This smaller stomach is not able to hold so much food. It is also noted that this procedure is meant to reduce the production of ghrelin which is an appetite-regulating hormone hence lessening the desire to eat. One should also note that the absorption of food is not affected by this procedure.

Biliopancreatic diversion with a duodenal switch

A section of the intestine is closed off in the middle, and the other stomach parts are reconnected to the duodenum to act as the duodenal switch. The section of the intestine removed is reattached to the last part of the intestine to allow the digestive juices flow into the stomach making it the biliopancreatic diversion.

Due to these changes, the food bypasses a bigger portion of the intestines hence the nutrients absorbed are limited. The size of the stomach having being reduced goes a long way in helping with weight loss.
