Further a bypass of the first section of the small bowel is created during which the bilio-digestive enzymes joining the digestion of the nutrients about 1.5m downstream after the stomach.

The Roux-en-Y gastric bypass (RYGB) usually leads to a quick weight loss. This operation can be applied in eating disorders such as binge eating (uncontrolled over eating) or sweet eating (preferably high-calorie sweets or beverages such as fruit juices, soft drinks). The RYGB induces hormonal changes, which affect the regulation of the blood sugar. This significantly improves an already existing Diabetes in most of the patients. Independently of any preexisting diabetes the intake of carbohydrate-rich food after a RYGB can cause temporary discomfort, dizziness and sweating (dumping).
