Sleeve gastrectomy
Roux-en-Y Gastric Bypass
Adjustable gastric band/“Lap band” NOT RECOMMENDED

What is a sleeve gastrectomy?
Majority of the greater curvature of the stomach is removed. The new tubular stomach has a small capacity and is resistant to stretching since the fundus is absent, and has fewer ghrelin-producing cells
83
What happens in a Roux-en-Y gastric bypass?
A small stomach pouch is created and then directly connected to the small intestine. The pouch can only hold 1 oz of food, causing a feeling of fullness after a very small amount of food. Over time, the pouch will stretch to hold about one cup. The body absorbs fewer calories since food bypasses the majority of the stomach and duodenum. Leads to decreased appetite and improved metabolism by changing the release of various hormones.
