Is weight loss surgery reversible?

December 11, 2023 | Weight Loss

You may be wondering if weight loss surgery is reversible. This depends upon the type of operation performed.

With many advancements over the past few decades, weight loss surgery, also know as bariatric surgery, is considered a safe way to lose a significant amount of weight. As patients consult with Dr. Hesham Atwa and his team at Long Island Laparoscopic Doctors, they sometimes ask ‘Is weight loss surgery reversible?’ You may be wondering the same.

It is a valid question. However, Dr. Atwa believes that no one should go into weight loss surgery with the mindset that it is reversible. Rather, they should review all options with their surgeon and select weight loss surgery with the understanding that it is a wonderful tool to lose weight – especially when used properly as he and his team teach all of their patients. This comprehensive education begins prior to surgery and extends throughout the entire first year after surgery and beyond.

When it comes to answering the question of if weight loss surgery is reversible, the answer is ‘Yes’ and ‘No’. Meaning that it is reversible for some procedures and not for others – and reversal of any procedure comes with considerable risk.

Adjustable Gastric Band

First let’s address the adjustable gastric banding procedure which is not as commonly performed today as in years past. This type of weight loss surgery may be reversible since the device can be removed.

Gastric Bypass

Second, let’s address the gastric bypass procedure. With this type of weight loss surgery, it is anatomically reversible since the parts of the stomach and small intestine can technically be put together again. However, this is not recommended and carries a high degree of risk.

Sleeve Gastrectomy

Third, let’s address the sleeve gastrectomy. This procedure is not reversible since the portion of the stomach that is removed in order to create your new ‘medium banana sized’ gastric pouch cannot be replaced.

It is important to seriously consider your need, your desire and your motivation for weight loss surgery. If you do your research, discuss this openly with your surgeon and surround yourself with supportive people and a supportive ongoing weight loss surgery program, success is likely to follow!
