Gastric By pass


The bypass technique is different because in addition to reducing the size of the stomach, the surgeon creates a kind of food bypass, resulting in food restriction and malabsorption.

Doctors consider this operation to be a success only when their patients recover from morbid obesity, i.e. when they lose half their excess weight within eighteen months of the operation. This happens in 70% of cases.

Cette intervention a un double rôle : elle traite l’obésité morbide car elle permet une réduction de 70% de l’excès de poids sur une durée de 12 à 18 mois et dernière découverte: elle permet de traiter ou améliorer le diabète type 2 récent (de moins de 5 ans) par ses effets hormonaux.

This procedure has a dual role: it treats morbid obesity because it allows a 70% reduction in excess weight over a period of 12 to 18 months and, lastly, it can treat or improve recent type 2 diabetes (less than 5 years old) through its hormonal effects.

In this case, an appropriate treatment will be rapidly implemented. Our team has performed more than 1,200 bypasses (800 omega bypasses and 400 Roux Y bypasses), with an average operating time of 1.5 hours and a hospital stay of 3 days.

Sugary snacks are not well tolerated, especially with the classic bypass
Because of the “dumping syndrome”, which is the ingestion of very sweet foods in large quantities, a general feeling of malaise and an acceleration of the pulse appear, this syndrome is due to the massive and rapid arrival in the intestine of foods very rich in fats or sugars, it is considered a benefit for the operated patients.

Vitamin deficiencies are common :

Oral supplementation with vitamins and trace elements is essential.
The various nutrients must be taken as a supplement to the diet, in the form of capsules or sachets.

  • Average duration of the intervention: 1h30 to 2 hours
  • Average length of stay: 3 to 5 days

Complications of gastric bypass surgery are fortunately rare, but are important to know.

  • Surgical complications: ulcers, leaks or narrowing at the junction between the stomach and the intestine, bleeding, obstruction of the intestine
  • Nutritional deficiencies
  • Functional complications: hypoglycaemia after meals, dumping syndrome, diarrhoea.
  • The mortality rate remains low, at 0.5%.

The bypass patient will have to take vitamins for life from the first month (MVM PROWELL – SURGILINE – FITFORME). They will be required to undergo regular check-ups in this respect. 

Before leaving the clinic, an orthopaedic surgeon will come and measure your belly to provide you with a tailor-made girdle, to prevent excessive sagging of the skin.
