Are you considering weight loss surgery as an option but are confused by the differences between gastric sleeve surgery (also known as sleeve gastrectomy) and gastric bypass (also known as RYGB), as well as the advantages and disadvantages of each surgery?

In this blog, we will compare gastric sleeve vs gastric bypass, help you understand the differences between each surgery, and outline the criteria that make one or the other more suitable for you.

What Is Gastric Sleeve Surgery, and What Is Gastric Bypass Surgery?

Gastric sleeve surgery refers to a type of bariatric surgery where a large portion of the stomach—around 70% to 90%—is laparoscopically removed, leaving the remaining section shaped like a narrow tube or, as the name suggests, a “sleeve.”

As for gastric bypass, it is a type of bariatric surgery where the stomach size is reduced, followed by a connection of the smaller pouch directly to the lower part of the small intestine. This helps limit food intake and reduce nutrient absorption, making it a very effective surgery for sustained weight loss.

Gastric Sleeve vs Gastric Bypass: Similarities and Differences

Similarities Differences
Both are well-researched and approved by the bariatric community as safe weight loss options. Gastric sleeve surgery can worsen symptoms of gastroesophageal reflux disease (GERD), while gastric bypass may improve it.
Both have helped millions lose weight across the globe. Gastric bypass may generally be better for type 2 diabetes patients.
Both involve a reduction in stomach size. Gastric sleeve is a permanent procedure, while gastric bypass can technically be reversible.
Both require a specialized plan after the surgery. Gastric bypass requires lifelong vitamin supplementation, while some mini-gastric sleeve patients do not require lifelong supplementation.

Mini sleeve surgery is a modified procedure that uses ultra-small laparoscopic tools to reduce invasiveness and minimize side effects. Learn more about it.

Finally… Which Surgery Is More Suitable for You?

One cannot simply decide which surgery is better for you without a proper medical evaluation. Generally speaking, when comparing gastric sleeve vs gastric bypass, gastric bypass can be better for some diabetic patients, while gastric sleeve surgery is a more straightforward procedure that does not involve complex changes in the digestive system.

A doctor can decide based on these factors, along with others such as your medical history, whether you had a bariatric surgery before, and whether you are able to stick to the required plan.

Furthermore, a doctor might decide that another option, such as weight loss medications or simply lifestyle changes, is a better option for you.
