Gastric Bypass ( Roux-en-Y ) in India

Roux-en-Y Gastric Bypass (RYGB) is a bariatric surgery that reduces the size of the stomach and reroutes part of the small intestine. It helps patients lose weight by limiting food intake, reducing absorption of some nutrients and changing gut hormones involved in appetite and blood sugar regulation.  

Main mechanisms

• Restriction: The small pouch limits the amount of food eaten at one time.

• Hormonal changes: Gut hormones such as GLP-1 and PYY can increase satiety and improve glucose regulation.

• Reduced nutrient absorption: Some absorption is reduced because food bypasses the duodenum and part of the jejunum.
