Gastric Sleeve vs. Gastric Bypass: Which Is Right for You?

Patients considering bariatric treatment may wonder if gastric sleeve vs. gastric bypass surgery will yield them better results. While both options can result in dramatic weight loss, the procedures differ in terms of surgical approaches, dietary guidelines, and long-term effectiveness. Dr. Liza María Pompa González at LIMARP® in Tijuana, MX, can evaluate your candidacy and help you determine which procedure will deliver optimal results for you.

Gastric Sleeve Surgery at a Glance

This permanent weight loss surgery reduces the size of the stomach by as much as 85 percent. The remaining portion of the stomach is formed into a tube or sleeve shape. By restricting stomach size, the patient feels fuller faster and consequently does not need to eat as much. The procedure also removes the hormone responsible for stimulating hunger.

Gastric Bypass Surgery at a Glance

Gastric bypass surgery relies on two surgical approaches to help patients achieve significant weight loss. The first of these reduces the size of the stomach to limit caloric intake, much like a gastric bypass. The second procedure rearranges the intestine so that the body absorbs less digested food and fewer calories, which further aids in weight loss.

Notable Differences

The key difference between these two bariatric procedures is the amount of weight lost. In general, gastric bypass surgery can help patients lose more weight than a gastric sleeve. This is largely due to the fact that gastric bypass results in fat malabsorption due to intestinal redirection, while gastric sleeve does not. However, there is a downside: bypass malabsorption makes it harder for the body to absorb essential nutrients and minerals. Gastric bypass patients therefore need to take vitamins and dietary supplements for the rest of their lives to ensure proper nutritional uptake.

Since gastric bypass is a more complex surgery with a higher risk of complications, it is typically reserved for more serious cases. Dr. Pompa may recommend the procedure for patients with a BMI of 40 or more. It is also an option for patients with life-threatening obesity-related health concerns, such as type 2 diabetes.

On the other hand, patients with a BMI of 50 or more generally undergo gastric sleeve. In such instances, gastric sleeve surgery can be a first step to lower weight, with patients later undergoing a second, more complex procedure, such as gastric bypass. As a result, patients who suffer from medical problems that might otherwise preclude them from complicated surgeries are often good candidates for a gastric sleeve procedure.
