Diet & Exercise Program for Gastric Sleeve Patients

Bariatric surgery involves reducing the size of your stomach to reduce food intake and promote weight loss. The procedure is permanent and requires a lifetime commitment to a maintaining a healthy lifestyle. The most common types of bariatric surgery are gastric bypass, lap-band and gastric sleeve. Gastric sleeve surgery is a relatively new type of bariatric surgery.


The surgeon uses a laparoscopic tool to make small incisions in the abdomen. He then inserts a viewing tube with a small camera, or laparoscope, into the incisions, which allows him to see inside the abdomen during the surgery. He inserts tiny instruments into the incisions to remove 85 percent of the stomach so that it takes the shape of a sleeve or tube. The surgeon then closes the new sleeve-shaped stomach with staples. You will spend one or two days in the hospital before being released, and recovery can take a few weeks. Your abdomen will be swollen and sore. Your doctor may prescribe medication for the pain. You will also have to become reaccustomed to eating regular food.
