In bariatric surgery , interventions whose sole objective is the extraction of fat, such as liposuction or abdominoplasty, are not included. There are different types of surgical procedures:
Gastric bypass:- :- One of the most commonly performed processes is a change in the amount of food eaten and its absorption through changes in the disposition of the gastrointestinal tract, which significantly reduces ingested calories. To do this, the surgeon cuts the upper part of the stomach, sealing the rest. The result is a walnut-sized bag with the capacity to hold approximately one ounce of food. Finally, the small intestine is cut and sewn directly into the new stomach. In this way, when food is ingested, it will pass through this new digestive system. It is a very safe type of surgery with excellent results, with a fairly high rate of effectiveness, which is why it is called the gold standard of bariatric techniques.

Adjustable Gastric Band:- In this bariatric surgery, the specialist places a ring with an internal inflatable band in the upper part of the abdomen, forming a small pouch. As in the previous procedures, the patient feels increasingly full while eating. Inside this gastric band is a circular balloon filled with a saline solution, so the surgeon can adjust the size of the bag.
Currently, it is one of the procedures that is performed less and less frequently than the previous ones, as it is associated with more complications, the need to remove the band predominates due to the patient’s intolerance to food.
Vertical Gastrectomy:– Weight loss is achieved by reducing the volume of the stomach by about 80%.
Plicated Tubular Gastroplasty:- The stomach is folded inward, reducing its capacity.
Duodenal Switch:- This is similar to gastric bypass, only in this case the diversion into the small intestine is inserted at the level of the duodenum so that only 50% is used for the absorption of food.
Biliopancreatic Diversion:- This is also known as “mixed surgery” and involves two separate procedures. On the one hand it is similar to the gastric sleeve and on the other hand the small intestine is divided into two parts. In this way, food passes through one section, bypassing most of the small intestine. It helps in reducing the total calories and nutrients absorbed by the body.
The benefit of this intervention for patients is a significantly greater weight loss compared to previous procedures. However, a lack of essential vitamins, minerals, and proteins can lead to complications in the body. This is why it is not done very often.
