During the procedure, your surgeon uses surgical staples to separate a small part of your stomach into a pouch, and then attaches your small intestines to this pouch. Afterward, when you eat, food will only go into the pouch. You won’t be able to eat as much as you did before surgery, so you’ll feel full faster. This can help with gradual, safe weight loss. In most cases, people are able to lose 60 to 70% of their extra body weight after a Roux-en-Y.
Roux-en-Y is often done laparoscopically. This means smaller incisions, so you’ll heal faster with less scarring. The procedure usually takes about 2 hours to perform and requires a hospital stay of 2 to 3 days.
