Gastric Balloon

The gastric balloon is a minimally invasive and temporary bariatric procedure that does not involve any cutting or stapling and is performed endoscopically (through the mouth). It consists of placing a silicon balloon in the stomach to occupy space to provide an earlier sense of satiety and fullness. Since this procedure does not involve any physical alteration to a patient’s anatomy, it is viewed as being simple and safe while also being reversible.  

How it Works

The gastric balloon is deflated at the time of insertion and enters the body through the mouth and esophagus. A syringe is then used to fill the balloon once in the stomach. The purpose of the balloon is to occupy space so a patient will feel full faster, helping them to lose weight. The balloon is left in the patient for 6 months while the patient pursues a medically supervised weight loss program. After balloon removal, it is expected that the patient will continue to live a healthy lifestyle and maintain their weight loss.

The gastric balloon procedure takes about 20 minutes to perform and patients can expect to go home the same day as their procedure. An additional procedure will be required to remove the balloon 6 months from insertion. Patients can return to work the next day and resume normal actives when comfortable. 


Patients who have the gastric balloon inserted can expect to lose about 20 to 30% of their excess body weight within 6 months.
*Excess body weight is the percentage of how much weight was lost based on how much you have or want to lose.
Low risk and removable
Long term cost savings as a result of reduced medical care
Improvement in overall health and quality of life


Before considering any surgical procedure, you should be familiar with the potential risks.
Minor complications that uncommon and can be managed fairly easily:
  • Nausea or vomiting
  • Gastric discomfort
  • Back or abdominal pain
  • Acid reflux or indigestion
  • Weight gain or failure to lose satisfactory weight  
Major complications, that could result in re-operation:
  • Balloon deflation / migration resulting in potential bowel obstruction
  • Bleeding
  • Perforation
