Roux-en-Y Gastric Bypass (RYGB) — pronounced “roo-en-why” — is the most commonly performed weight-loss procedure. It has been in practice for more than 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 in surgical procedures).
RYGB Promotes Weight Loss In Two Ways
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 “Rouxlimb.” The new stomach pouch restricts the amount of food you can eat, making you feel full after eating only a small amount of food.
Mal-Absorbtion: Once the smaller pouch is created, the surgeon reroutes your digestive system to bypass the larger part of your stomach and part of your small intestine. The result of the bypass is you absorb fewer calories and nutrients from the food you eat (mal-absorption).
- Average weight loss is greater than with other procedures, such as Laparoscopic Adjustable Band and Sleeve Gastrectomy.
- Co-morbidities — conditions related to excess weight, such as type 2 diabetes and hypertension — may begin to improve even before you lose much 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.
- Post-operative healing: Surgery is a bit longer because the digestive organs are rerouted. There is more pain, and it takes longer to heal from this procedure than from a Lap Band.
- The procedure reduces your ability to absorb nutrients and calories; you will need to take vitamin supplements for the rest of your life.
- You will need to follow the low-sugar and low-starch diet guidelines following surgery, 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
