Understanding the Difference Between Gastric sleeve and Gastric bypass Surgery



Deciding to undergo gastric surgery can be an overwhelming decision. There are several types of procedures, each with its risks and benefits. The two most common are sleeve gastrectomy and Roux-en-Y gastric bypass. Although they both involve reducing the size of the stomach, there are some key differences between the two types of surgeries. Let’s break down the basics.

Sleeve Gastrectomy Basics

A sleeve gastrectomy is a procedure where approximately 85 percent of your stomach is removed, leaving behind a tube-shaped pouch that holds significantly less food than your original stomach did. It is a restrictive procedure because it limits how much food you can eat in one sitting, thus resulting in weight loss. It also affects hormone production in the body which helps to reduce hunger cravings and control blood sugar levels more effectively. However, since this procedure does not affect how nutrients are absorbed by the body, malabsorption risks are lower than with a bypass procedure.

Roux-en-Y Gastric bypass Basics

The Roux-en-Y sleeve vs bypass is a combination of restrictive and malabsorptive procedures. A small stomach pouch is created using staples or surgical bands which restricts food intake while also rerouting part of your digestive tract so that fewer calories are absorbed by the body during digestion. This type of surgery is considered to be more effective for long-term weight loss but it has higher risks associated with it due to potential complications from malabsorption such as nutritional deficiencies, anemia, bone density issues, etc. It also requires more follow-up care than a sleeve due to those malabsorption risks mentioned previously.


Understanding the differences between the sleeve and bypass surgery can help you make an informed decision about which type may be best for you depending on your individual needs and health condition. Both procedures involve reducing the size of your stomach but sleeve involves only restricting food intake whereas bypass further reduces calorie absorption as well as limiting how much you can eat at once. No matter which route you choose, it’s important to remember that following recommended postoperative protocols such as diet changes and regular checkups will help maximize success after either type of surgery!
