A gastric band is fitted under general anesthesia. It is usually done in an outpatient clinic, and the individual usually goes later the same day.
The procedure is minimally invasive. It is performed through keyhole incisions. The surgeon makes between one and five small surgical cuts in the abdomen. Surgery is carried out using a laparoscope, a long narrow tube with a camera. The procedure often takes 30 to 60 minutes.
The patient should not eat from midnight before the day of the surgery. Most people can resume most normal activities within 2 days, but they may need to take a week's leave from work.
