What You Need to Know about Revisional Weight Loss Surgery

revision bariatric surgery

Weight loss surgery has become a popular option for those individuals who have tried and failed to lose weight through traditional methods. One of the most effective and commonly performed procedures is gastric bypass surgery, which involves creating a small stomach pouch to limit the amount of food that can be consumed. However, not all patients achieve their desired weight loss outcome with this surgery, leading to the need for revisional weight loss surgery. In this article, we will explore the basics of revisional weight loss surgery.


What is Revisional Weight Loss Surgery?

Revisional weight loss surgery, also known as revisional bariatric surgery, is a procedure performed on patients who have already undergone a primary weight loss surgery but have not achieved the desired weight loss outcome. This surgery aims to modify or correct the initial surgery's effects to achieve the desired weight loss outcome. It is typically more complex than the primary surgery, as it involves revising or altering the stomach's original anatomy, which can pose additional risks.


When is Revisional Weight Loss Surgery Required?

Revisional weight loss surgery is often required in cases where the patient has not lost enough weight despite having undergone primary weight loss surgery. This can be due to various reasons, such as the stomach pouch stretching out or the patient not following the recommended diet and exercise regimen. The surgery may also be recommended in cases where the patient experiences complications or side effects from the primary surgery, such as dumping syndrome or malnutrition.


Types of Revisional Weight Loss Surgery

Several types of revisional weight loss surgery can be performed, depending on the patient's specific situation. Some of these surgeries include:

  1. Endoscopic procedures: This type of surgery involves using an endoscope to make changes to the stomach pouch from inside the body. This is the least invasive type of revisional surgery and can be performed on an outpatient basis.
  2. Conversion surgery: This involves converting the primary surgery into a different type of surgery, such as from gastric banding to gastric bypass.
  3. Reoperation: This involves further surgical intervention to revise the effects of the primary procedure, such as repositioning the band in gastric banding surgery.


Risks and Benefits of Revisional Weight Loss Surgery

Like all surgeries, revisional weight loss surgery carries risks, including infection, bleeding, and anesthesia-related complications. However, the benefits of the surgery can outweigh these risks, as it can help patients achieve their desired weight loss outcomes and improve their quality of life. It can also help address any complications or side effects from the primary surgery and improve overall health by reducing the risk of obesity-related health conditions.




Revisional weight loss surgery is a complex and highly specialized type of surgery that can help patients achieve their desired weight loss outcomes. Depending on the patient's specific situation, different types of revisional surgeries can be performed, each with its own risks and benefits. If you have undergone primary weight loss surgery and have not achieved the desired outcome, talking to a qualified bariatric surgeon can help determine if revisional surgery is right for you. Always remember to follow your recommended diet and exercise regimen to achieve and maintain a healthy weight and lifestyle. For a bariatric revision consultation, contact
