Bariatric surgery is an essential part of bariatric treatment. Its aim is to combat or stop weight gain, especially when it strongly threatens health.

Bariatric surgery involves reducing the volume of the stomach and altering the digestive tract. It is performed using a laparoscopic method. The result of the treatment is a reduction in the absorption and consumption of food and the effective weight loss. Bariatric surgery is most often performed on patients who suffer from concomitant diseases (such as diabetes) in addition to being overweight.
