📖About Gastric Bypass
Gastric bypass is a bariatric surgical procedure that creates a small stomach pouch and reroutes the small intestine to connect directly to it, both restricting the amount of food that can be eaten and reducing calorie and nutrient absorption, resulting in substantial weight loss and improvement of obesity-related conditions. Because the procedure bypasses a section of the small intestine along with most of the stomach, it tends to produce faster and often greater weight loss than sleeve gastrectomy, along with particularly strong improvement in type 2 diabetes. Patients must commit to lifelong vitamin and mineral supplementation, since the altered digestive route reduces the body's ability to absorb certain nutrients from food alone. The rerouted anatomy also changes how quickly food and sugar reach the small intestine, which explains the dumping syndrome symptoms some patients experience.
