Bariatric Surgery
Gastric Bypass
Gastric bypass, or gastric short-circuiting, is a bariatric surgery procedure combining restriction and malabsorption. It involves creating a small gastric pouch connected directly to the small intestine, thus bypassing most of the stomach and the beginning of the small intestine. It is the standard procedure for severe obesity with comorbidities.

Procedure of the Intervention
The procedure is performed laparoscopically. The surgeon creates a small gastric pouch (30-50 ml) from the upper part of the stomach, separating it from the rest of the stomach. The small intestine is then cut, and the distal portion is connected to this pouch (alimentary loop). The proximal portion is reconnected further down to allow digestive secretions to reach the food. This Y-shaped anastomosis creates a bypass that limits absorption.
Post-operative monitoring and recovery
Liquid diet for 2 weeks, then pureed, then normal textures gradually over 6-8 weeks. Time off work for 3 to 6 weeks. Strict and lifelong vitamin supplementation is essential. Close monitoring for 2 years, then annual monitoring for life.
Expected Results
Gastric bypass surgery allows for a 60 to 80% loss of excess weight within 18 months. Diabetes remission occurs in 80-90% of cases, often within the first few weeks. The effect on digestive hormones explains these exceptional metabolic results. The results are long-lasting, provided that follow-up care is maintained.
