Roux-en-Y Gastric Bypass (RYGB) — pronounced "roo-en-why" — is the most commonly performed weight-loss procedure in the United States. It has been in practice for over 30 years and provides an excellent balance of weight loss and manageable side effects. The operation can be performed laparoscopically (small incisions to the abdomen) or robotically (computer-assisted surgery used to aid surgical procedures).

RYGB comprises two components

Restriction: The surgeon separates the upper portion of the stomach from the lower portion. The upper portion (or the "pouch") is then connected to a limb of the small intestine called the "Roux limb." The new stomach pouch restricts the amount of food you can eat, making you feel full after eating only a tiny amount.

Mal-Absorption: Once the smaller pouch is created, the surgeon reroutes your digestive system to bypass the more significant part of your stomach and small intestine. The bypass results in you absorbing fewer calories and nutrients from your food (malabsorption).

As a result, all the abnormal hormones are reduced and the “good” hormones are boosted, which signals your brain and body to gradually lose weight. This mechanism also improves insulin resistance in your body, resulting in marked improvement in your diabetes. Hunger is greatly reduced, craving for carbohydrates is reduced and the amount of food that can be consumed is also reduced and the absorption of calories and nutrients is also decreased.


  • It is the gold-standard bariatric procedure with the longest and most robust track-record
  • Average weight loss is more significant than other procedures, such as Laparoscopic Adjustable Band and Sleeve Gastrectomy.
  • Co-morbidities, conditions related to excess weight, such as type 2 diabetes, PCOD, and hypertension — may improve even before you lose weight.
  • Weight loss is more rapid than with the Lap Band if you follow dietary guidelines.
  • RYGB doesn't require any devices to stay inside you.


  • The procedure reduces your ability to absorb nutrients and calories; you must take iron, mineral, vitamin, and protein supplements for the rest of your life.
  • Following surgery, you must follow the low-sugar and low-starch diet guidelines since you may experience discomfort, including vomiting and diarrhea.
  • This procedure is not reversible.
  • Complications include the possibility of leaks, bleeding, blood clots, infection, and blockages.
