How does a gastric sleeve work?

Last Updated : May 30, 2024

A gastric sleeve, also known as sleeve gastrectomy, is a type of weight loss surgery that involves removing a large portion of the stomach, reducing the size of the stomach and limiting the amount of food that can be consumed. This procedure is performed using minimally invasive techniques and results in a permanent reduction in the size of the stomach.

The gastric sleeve procedure works by creating a narrow, tube-like stomach, which reduces the amount of food that can be consumed and reduces hunger. The reduction in hunger can lead to decreased food intake and weight loss, which can help individuals to achieve a healthier weight and improve their overall health.

During the procedure, a large portion of the stomach is removed using a laparoscopic or minimally invasive surgical approach. The remaining portion of the stomach is then stapled to create a narrow, sleeve-like shape. The procedure typically takes one to two hours to complete, and patients are usually able to return home within a few days.

One of the benefits of the gastric sleeve procedure is that it is less invasive than other weight loss surgery options, such as gastric bypass. The procedure does not involve rerouting the small intestine, which means that there is no risk of malnutrition or other nutrient deficiencies. Additionally, the gastric sleeve procedure does not involve any adjustments or devices that need to be periodically adjusted, like an adjustable gastric band.

Another benefit of the gastric sleeve is that it can lead to significant weight loss in a short period of time. Studies have shown that individuals who undergo gastric sleeve surgery can expect to lose 50-60% of their excess weight within the first year after the procedure. This weight loss can improve overall health, reduce the risk of obesity-related health problems, and improve quality of life.

It’s important to note that gastric sleeve surgery is not a quick fix, and individuals who undergo the procedure will need to make lifestyle changes, such as a balanced diet and regular exercise, to maintain their weight loss over the long term. Additionally, the gastric sleeve procedure may not be the right choice for everyone, and it is important to discuss the benefits and potential risks with a qualified healthcare provider to determine if it is the right choice for you.

In conclusion, the gastric sleeve is a type of weight loss surgery that involves reducing the size of the stomach and limiting the amount of food that can be consumed. The procedure is less invasive than other weight loss surgery options and can lead to significant weight loss in a short period of time. If you are considering gastric sleeve surgery, it is important to discuss the procedure with a qualified healthcare provider to determine if it is the right choice for you.
