Gastric sleeve surgery is designed to be a permanent solution for weight loss and improved health. During the procedure, a significant portion of the stomach is removed, including the stretchy part that allows for expansion. As a result, the surgery is not reversible in the traditional sense.

However, it is important to note that in rare and unusual circumstances, gastric sleeve surgery can be converted to another type of weight loss procedure, such as a gastric bypass or duodenal switch. These situations are exceedingly uncommon.

In fact, the permanence of gastric sleeve surgery is one of its key advantages, as it allows for sustained weight loss and long-term improvements in health. By removing the stretchy portion of the stomach, the procedure helps to reduce hunger and promote a feeling of fullness, making it easier for patients to maintain a healthy diet and lifestyle.
