For patients who are overweight but are still indecisive about undergoing surgery, endoscopic intra-gastric balloon is an option. A saline-filled balloon will be placed inside the top of the stomach, reducing stomach volume and giving a sensation of satiety. This is only a TEMPORARY treatment, as the balloon cannot be placed in the stomach for more than 6 months. Patients should maintain a balanced diet and exercise regularly for effective weight loss.

Procedures of Intra-gastric Balloon

Placement of gastric balloon is relatively simple compared to other surgeries. Patients will be sedated and a balloon will be placed inside the stomach with the help of an endoscope. Saline with blue dye will then be injected into the balloon via a catheter. The volume to be injected depends on the patient’s condition, which is about 400-600ml in general.

The procedure takes around 30 minutes and hospitalization is not usually required. Fluid diet is usually advised for the first week after procedure. Also during the first week after balloon placement, patients may experience stomach discomfort or pain, vomiting and abdominal distention.

  • Widely applicable: Patients with lower BMI may also consider to undergo this low risk procedure.
