Obesity surgery encompasses various techniques, such as the Sleeve, Bypass, and BariClip. It is specialist surgeon Dr. Patrick Noël who will guide you toward the most suitable solution for your case, following a thorough evaluation of your overweight condition. The treatment that best suits you is selected based on carefully considered criteria.

Gastric Sleeve


This operation reduces the size of the stomach by resecting almost 75% of its volume. Thus the stomach which has the form of a bag takes the form of a narrow tube. With this technique, the feeling of hunger decreases considerably with the reduction in the secretion of Ghrelin, a hormone secreted by the removed part of the stomach and which is responsible for the feeling of hunger.


The sleeve gastrectomy allows a loss of 50% of excess weight. Then, the weight loss bends a little to generally stabilize around a loss of 70% of the excess weight.

The intervention is performed by laparoscopic route, lasts approximately one hour and requires two to three days of hospitalization.

This technique consists of bypassing 150 to 200 cm of small intestine depending on the excess weight by making a small gastric pouch. This will reduce daily food intake and intestinal absorption of ingested food.

There are two variants of this technique depending on the modality of the intestinal short-circuit: the ByPass in Y and the ByPass in Omega .


This intervention results in the loss of 50% of the excess weight, then the weight loss declines a little to generally stabilize around a loss of 80% of the excess weight.

This intervention is done by laparoscopic way and lasts 2 hours.  and requires an average hospital stay of three days.

What is BMI and how to calculate it  ?

BMI stands for Body Mass Index. It is a unit of measurement that relates a person's height to weight.

The rule is simple:

BMI = your weight (in kg) / [your height x your height] (in meters).

The higher the index, the greater the person's weight in relation to their height.


Once the BMI has been calculated, the figure obtained makes it possible to situate oneself:

  • From 25 to 30, we speak of overweight

  • 30 to 35 is moderately obese.

  • From 35 to 40 is severe obesity

  • Over 40 is morbidly obese

Who is obesity surgery intended for?

Bariatric surgery is mainly for people who feel bad about themselves because of overweight and obesity problems and for whom conventional treatments: diets, medical monitoring, sport have failed.


Obesity surgery is intended for patients with excess weight exposing them to health complications.

Some criteria are essential to benefit from obesity surgery in Tunisia:

  • If you have been obese for more than 3 years with a BMI greater than 30 .

  • Failure of other treatments in your weight loss

  • You are motivated and knowledgeable

  • You are not addicted to alcohol and drugs

  • You don't suffer from any  endocrine pathology


The implementation of a bariatric surgery project requires a lot of involvement because the most important thing in this process is above all your will.

Why resort to cosmetic surgery after bariatric surgery

The sudden weight loss resulting from the different diets imposed by bariatric surgery leads to the appearance of excess skin that will have to be removed to regain the harmony of your line.  


You can opt for cosmetic surgery in Tunisia to get rid of excess skin and fat in one operation with  rapid recovery.
