Gastric sleeve, also known as sleeve gastrectomy, is a weight loss surgery that reduces the size of the stomach, leading to a decrease in food intake and weight loss. The procedure involves removing a large portion of the stomach, leaving a sleeve-shaped portion that is about the size and shape of a banana. This reduction in stomach size not only leads to weight loss but also causes hormonal changes that can help regulate hunger and improve satiety.
The operation of gastric sleeve is performed using minimally invasive laparoscopic techniques. The surgeon makes several small incisions in the abdomen and uses special instruments to remove the larger portion of the stomach. The remaining sleeve of the stomach is then stapled closed, creating a smaller stomach pouch that holds significantly less food. This results in a decrease in food intake, and weight loss over time.
Gastric sleeve surgery is typically performed on individuals who are significantly overweight or obese, with a body mass index (BMI) of 40 or higher, or a BMI of 35 or higher with additional weight-related health problems. The procedure is typically considered a less invasive option compared to other weight loss surgeries, and patients can typically go home the same day as the surgery and return to normal activities within a few weeks. However, it is important to note that gastric sleeve is a major surgery and should be carefully considered with the guidance of a healthcare provider and weight loss specialist.
