Difference between Gastric Bypass and Gastric Sleeve

If you’re considering bariatric surgery to help aid in your weight loss journey, understanding the differences between gastric bypass and gastric sleeve procedures can be a vital part of the decision-making process. While both surgeries offer serious health benefits for those suffering from obesity and type 2 diabetes, there are certain pros and cons associated with each procedure that should be weighed carefully before selecting which path is right for you. In this blog post, we’ll break down what gastric bypass and gastric sleeve surgeries entail as well as discuss potential risks versus rewards so that you have an informed picture of both procedures when making your choice. Read on to find out more!

What is Gastric Bypass?

Gastric Bypass is a weight-loss surgery that helps people lose excess weight by altering the digestive system. It is usually seen as the last resort for people who seriously need to address obesity-related health issues and are unable to do so through diet and exercise alone.

  • Gastric bypass surgery changes how food moves through the stomach and intestines, limiting the amount of food that can be eaten in one sitting and allowing fewer calories to be absorbed.
  • This shift in digestion helps people reach their target goal quicker, though it also requires lifelong lifestyle changes such as regular checkups, healthy eating habits, and daily exercise to control appetite and maintain weight loss.
  • Gastric bypass remains a valuable solution for those looking to make sustainable health changes while reducing the risk of associated medical conditions.

What is Gastric Sleeve?

Gastric Sleeve is a surgical procedure that reduces the size of the stomach, allowing for less food consumption and quicker feelings of fullness.

  • In this procedure, surgically 85-90% of the original stomach is removed, leaving only a thin “sleeve” or tube from which food can pass through.
  • Gastric Sleeve helps to reduce appetite and reduce feelings of hunger, leading to more appropriate portion control and consequentially helping people lose weight.
  • Gastric Sleeve has become popular in recent years as an effective treatment for severe obesity when traditional methods such as diet and exercise fail to provide lasting relief.

Additionally, Gastric Sleeve results in permanent changes to the body since it is not reversible like other forms of bariatric surgery. As with any surgery, there are risks associated with Gastric Sleeve so it’s important to consult with a doctor prior to undergoing the procedure.

Difference between Gastric Bypass and Gastric Sleeve

Gastric Bypass and Gastric Sleeve are two different types of bariatric surgeries which are performed to aid in weight loss.

  • Gastric Bypass, also known as Roux-en-Y Gastric Bypass, is a surgical procedure that involves reducing the size of the stomach and reorganizing its digestive process.
  • Gastric Sleeve surgery, sometimes referred to as sleeve gastrectomy, is a procedure where the size of the stomach is reduced through the removal of part of it.
  • Gastric Bypass has been seen to provide faster and more profound initial weight loss compared to Gastric Sleeve; however, Gastric Sleeve is overall easier to recover from and may have reduced risks involved with long-term nutrient deficiency compared to Gastric Bypass.

Ultimately, your doctor or surgeon will be best equipped to advise you on which procedure will be most suitable for your specific needs and lifestyle.


If you’re considering weight loss surgery, it’s important to understand the difference between gastric bypass and gastric sleeve procedures. Both surgeries are effective in helping people lose weight, but they work differently. Gastric bypass surgery separates the stomach into a small upper pouch and a large lower section. The small intestine is then connected to the upper pouch so that food only passes through this tiny area. This limits how much food a person can eat at one time. Gastric sleeve surgery removes about 80% of the stomach, leaving behind a banana-shaped organ. This procedure also reduces the amount of food a person can eat at one time, but does not involve separating or rerouting the intestines. So which surgery is right for you? That’s something you will need to discuss with your doctor. But we hope this article has helped you better understand the differences between gastric bypass and gastric sleeve surgery procedures.
