The gastric balloon is a non-surgical, endoscopic weight loss procedure where a saline filled balloon is placed into the stomach. The balloon reduces the amount one can eat and causes one to feel full sooner and longer. Patients can lose up to 3 times the amount of weight compared to diet and exercise alone. Candidates for this procedure typically have a BMI between 30-40 and usually prefer a non-invasive approach and/or are not a candidate for surgery.
The procedure is performed under sedation. The deflated balloon is introduced into the mouth and then is guided down the esophagus into the stomach where it is then filled with saline to the size of a grapefruit. The procedure takes about 20 minutes with patients returning home the same day. The balloon remains for six months during which time the patient works on diet and lifestyle modifications with the support of their weight loss program. Then after six months, the balloon is retrieved endoscopically in a manner similar to when it was placed. Over the course of the subsequent six months, the patient continues to partner with their weight loss team and work on a personalized nutrition and exercise program.
Side effects can include nausea, vomiting and abdominal pain. In rare circumstances the balloon can cause stomach or intestinal blockage or perforation.
