Bariatric surgery consists of surgically reducing the stomach capacity to restrict food intake and promote weight reduction.
Bariatric surgery is performed by laparoscopy, which requires small incisions (usually about 1 cm) to introduce the instruments.
There are several techniques to achieve weight loss. Sometimes the reduction of the stomach capacity is combined with a reconstruction of the intestinal transit to achieve an effect of food malabsorption.
Bariatric surgery usually lasts between 3 and 5 hours.
