Vertical sleeve gastrectomy (VSG) is a type of bariatric surgery that involves removing a large portion of the stomach to create a smaller, sleeve-shaped stomach. The smaller stomach reduces the amount of food that can be eaten at one time and leads to feelings of fullness after eating smaller meals. This can result in significant weight loss for individuals who have struggled to lose weight through diet and exercise.
During the VSG procedure, the surgeon removes approximately 80% of the stomach, leaving a narrow tube or sleeve-shaped stomach. The procedure is typically performed laparoscopically, which means it is minimally invasive and involves small incisions rather than a large open incision.
VSG is typically recommended for individuals with a BMI (Body Mass Index) of 40 or higher, or those with a BMI of 35-39.9 with obesity-related health conditions such as diabetes, sleep apnea, and high blood pressure.
VSG has several advantages over other types of bariatric surgery, including:
- It does not involve rerouting or bypassing the intestines, which reduces the risk of nutritional deficiencies.
- It is a simpler procedure with fewer potential complications.
- It results in significant weight loss, typically 50-70% of excess weight.
However, VSG also carries risks and potential complications, including bleeding, infection, and leaks at the surgical site. Patients should discuss the risks and benefits of VSG with their healthcare provider to determine if it is an appropriate option for their individual needs.
