During the procedure, a laparoscope (a thin tube with a camera) is inserted through small incisions in the abdomen. The surgeon then uses specialized surgical instruments to remove a large portion of the stomach, leaving behind a long, narrow tube-like structure.

Sleeve gastrectomy is generally considered a safe and effective weight loss surgery option for people with a body mass index (BMI) of 40 or higher, or a BMI of 35 or higher with one or more weight-related health problems. It can lead to significant weight loss, improvement in weight-related health conditions such as diabetes and high blood pressure, and an overall improvement in quality of life.

As with any surgery, there are risks associated with sleeve gastrectomy, including bleeding, infection, blood clots, and adverse reactions to anesthesia. It is important for people considering this procedure to discuss the risks and benefits with their healthcare provider and to carefully consider whether it is the right choice for them.
