Laparoscopic bariatic surgery (gastric bypass)


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.


Bariatric surgery requires a particularly thorough preoperative, especially with regard to anesthesia, due to the associated problems that obese patients often present. Preoperative tests include X-rays, blood tests, consultation with the anesthesiologist, etc.

Patients must undergo a preliminary test to evaluate their case with the participation of different specialists such as psychologists, surgeons, nutritionists, etc. They will decide together the specific characteristics of the intervention.

Also, if they have any chronic illness or regularly take medications, especially anticoagulants, they should inform the surgeon before surgery.


Patients will stay a few hours in the intensive care unit and three or four more days in hospital.

The day after the operation they can start taking a liquid diet and then patients should strictly follow the diet they have been given.

Patients should attend regular reviews with different specialists.
