How Weight Loss Balloon works

The 100% Non-Surgical Solution

Placing the balloon

Deflated weight loss balloon is inserted through your mouth and into your stomach.

The entire non-surgical, outpatient procedure takes about 20 minutes.

First, a diagnostic endoscopy is done to ensure that it is safe to perform the procedure. Once you are mildly sedated and comfortable, the procedure can begin.

Filled the balloon

The ballon is then filled with a sterile saline solution.

The deflated gastric balloon is inserted through the esophagus and into your stomach. A syringe is then used to fill the balloon, with a sterile saline solution, to about the size of a grapefruit.

Changing your habits

The balloon takes up enough space in your stomach to help ypu adapt to healthier portion sizes.

For the next six months the weight loss balloon is inside your stomach, reducing the amount you can eat, and re-training your brain to better anticipate when your stomach is getting full.

It’s during this time that open and constant communication with your support team is crucial to maximizing the benefits of weight loss system. This means regular face-to-face sessions with your treatment team, dietician, fitness trainer, psychologist and doctor.

During these first six months, with the stomach balloon and support team working in tandem, patients see the most drastic results - Losing 20 to 50 pounds (sometimes even more).

Removing the balloon

The ballon is removed 6 months later with a non-surgical procedure.

After you’ve had six months to change the way you eat and work with the support team to improve your nutrition, the balloon is removed. The simple and non-surgical procedure is very similar to the placement process, only taking 20 minutes.
