Sleeve gastrectomy is a weight loss surgery that involves the removal of a large portion of the stomach. During the procedure, the surgeon will create a small, banana-shaped stomach by removing approximately 80% of the stomach.
This surgery is typically performed laparoscopically, which means that the surgeon will make several small incisions in the abdomen and insert a tiny camera and surgical instruments to perform the procedure.
The surgery usually takes approximately one to two hours, and patients typically remain in the hospital for one to two days following the procedure.
Sleeve gastrectomy works by reducing the size of the stomach, which limits the amount of food that a person can eat. Additionally, the surgery may also result in hormonal changes that can help to reduce hunger and increase feelings of fullness.
People who undergo sleeve gastrectomy typically experience significant weight loss in the months following the procedure, with most people losing approximately 50 to 60% of their excess body weight within the first year.
People who undergo sleeve gastrectomy need to make significant lifestyle changes to achieve and maintain long-term weight loss and improved health. These changes include:

1. Eating a healthy diet: After surgery, patients need to gradually transition to a diet that is low in fat, sugar, and calories. Patients should focus on consuming high-protein foods, such as lean meats, fish, and beans, and avoid high-calorie foods and drinks, such as soda, candy, and fried foods.
2. Portion control: Patients need to learn to eat smaller portions and avoid overeating. The smaller stomach size after the surgery helps with portion control, but patients still need to be mindful of their eating habits.
3. Regular exercise: Exercise is an essential component of weight loss and improved health. Patients should aim to get at least 30 minutes of moderate-intensity exercise most days of the week.
4. Follow-up appointments: Patients will need to attend regular follow-up appointments with their doctor to monitor their weight loss progress and overall health.
5. Avoid smoking and alcohol: Smoking and alcohol consumption can have a negative impact on weight loss and overall health. Patients are advised to avoid smoking and limit alcohol intake after surgery.
