What is Gastric Bypass?

Gastric bypass (Roux-en-Y Gastric Bypass) is still considered by many as the “Gold Standard” of bariatric surgery. This procedure achieves weight loss by combining restriction with malabsorption, essentially decreasing how much food you can eat and how many calories your body can absorb.
