Roux-en-Y and Sleeve Gastrectomy
February 8, 2016

When it comes to the different types of weight loss surgery, there is no one size fits all answer for which type of procedure is right for you. Each patient is unique, and treatment will depend on several different factors including weight loss goals, weight-related health issues, risk and cost. Here we will explore the two most commonly performed procedures at U.S. Bariatric to help you gain a better understanding of how each procedure changes the digestive system.


The Roux-en-Y or gastric bypass is a restrictive and malabsorptive procedure in which a small stomach pouch is created to restrict food intake. Afterward, a Y-shaped section of the small intestine is re-routed and attached to the new pouch. This allows food to bypass the lower stomach and the upper parts of the small intestine, reducing the amount of calories and nutrients the body absorbs.

In most cases, the Roux-en-Y can be achieved through minimally invasive laparoscopic measures. This leaves patients with small incisions (about the diameter of a pencil eraser), which results in quicker recovery times, less scarring, and reduced risk of infection.

Sleeve Gastrectomy

In sleeve gastrectomy, the stomach is altered in to a banana-shaped sleeve, which is created by dividing and removing about 80% of the stomach. This tube is much smaller than the natural stomach, restricting the amount of food that can be eaten. This procedure is restrictive only, as no part of the digestive system is bypassed, so absorption remains the same.

The sleeve gastrectomy can also be performed laparoscopically in most cases, and takes about 30 minutes to complete. With both procedures, the patient is typically discharged from the hospital two days after the procedure and can return to work after about a week.

The decision to undergo weight loss surgery is a life-changing one, and can only be made between you and your doctor. Do your research to educate yourself before going into your consultation, and be sure to write down any questions you have for your surgeon so you don’t forget any details.
