The gastric bypass technique has been in use for more than forty years. It consists of reducing the size of the stomach to decrease food intake and by-passing part of the stomach and intestine so that less of the food is assimilated.

Advantages

  • expected weight loss of between 70% and 100% of excess weight, i.e. weight loss of approximately 30kg to 45 kg for a person of average height (1.70 m) with a BMI of 40 kg/m²
  • a quicker feeling of fullness during meals and a hormonal effect that reduces the feeling of hunger
  • a technique used for more than forty years, with well-known results, even in the long term
  • no removal of any organs (unlike the sleeve)
  • no insertion of foreign bodies (unlike the gastric band)
  • no gastric reflux

Disadvantages of the surgery

  • procedural mortality rate of 0.5% (source: HAS), caused mainly by cardiac or pulmonary problems.
  • possible complications: ulcer, gastric leak or shrinkage, haemorrhage, intestinal occlusion, dumping syndrome
  • vitamin tablets required for the rest of your life (2 tablets / day) to avoid the risk of vitamin deficiency
  • examination of the bypassed portion of the stomach by fibroscopy at a later date is impossible
