The stomach is a muscular sac that is important for absorbing food and preparing food for further digestion.
Gastric Sleeve surgery also referred to as the vertical sleeve gastrectomy or vertical gastric sleeve is a type of weight loss surgery that is opted for individuals who cannot have other types of bariatric surgeries safely. The surgery is performed laparoscopically under general anesthesia. During the surgery the stomach is reduced to about 25% of its original size by removing a large portion of it. The remaining stomach is a much smaller long vertical tube about the size of a banana. This restricts the amount of food a person can eat. The procedure is irreversible and should not be considered a quick-fix for weight loss. After the surgery, drastic lifestyle changes have to be made such as eating healthy diet, controlling portion sizes and doing regular exercise. The procedure is usually recommended in individuals who have either a BMI of 40 or more or a BMI of 35 or more along with a serious medical condition that can improve by losing weight such as obstructive sleep apnea, heart disease and type 2 diabetes.
