Medical treatment for clinically severe (morbid) obesity includes various combinations of low calorie diets, behavioral modification, physical exercise and pharmacological agents. The biggest problem with this type of approach is its inability to maintain a reduced body weight in most obese patients, with a high incidence of inefficiency in sustaining a 10% weight loss over time with this type of treatment.

Due to the serious risks related to this degree of obesity, the relatively low risk of surgical treatment and the ineffectiveness of medical or dietary interventions, as well as the severity that weight variations can bring as a result of inefficient conservative treatments (yo-yo effect) , bariatric surgery has been asserting itself in this universe, due to the good results not only in reducing the weight achieved and maintained, but also with the improvement of the diseases that accompany it. Surgery should be considered as a treatment for a debilitating and non-aesthetic disease.

The fundamental principle of obesity or bariatric surgery is to change the energy intake / absorption-consumption ratio, which in obesity is favorable to the first set, thus causing an accumulation of energy by increasing weight. Therefore, reducing food intake or absorption and increasing physical activity will cause weight loss by altering this dynamic.

The types of bariatric surgery can also be divided as follows:


Vertical Gastroplasty
Gastric Bands


Roux-en-Y gastric bypass
Ring bypass


Biliopancratic Derivation
Distal Roux-en-Y Gastric Bypass
Biliopancreatic shunt with “duodenal loop”
