Placing the Silicon Ballon in the stomach is a simple procedure which will take approximately 20-30 minutes and which will be carried out under light sedation by a Consultant Gastroenterologist.
  1. The doctor passes a special endoscope (camera) through the mouth, down the oesophagus (gullet) and into the stomach.
  2. A preliminary examination of the stomach is carried out and, assuming there are no abnormalities, the Silicon Balloon will then be passed into the stomach.
  3. The balloon is made of a soft and pliable silicone elastomer material and is inserted while in its smallest, deflated form.
  4. The swallowing process is made easier with the help of some local anaesthetics to help numb the throat area. Muscle relaxing medications are also used.
  5. Once the gastric balloon is inside the stomach, it is immediately filled with sterile saline through a small filling tube (catheter) attached to the balloon.
  6. Once filled, the doctor removes the catheter by gently pulling on the external end.
  7. The balloon has a self-sealing valve, and at this point the balloon is floating freely in the stomach.
  8. At the same time, a special dye is introduced into the balloon which will cause your urine to change colour (usually green) in the very unlikely event that the balloon ruptured or developed a leak.
Because there is no general anaesthesia involved, you will normally be able to leave hospital after a few hours of observation.
