Swallowable Intragastric Balloon


It is a weight loss method that is not indicated for obesity surgery and aims to reduce the quantity of food consumed in a meal by placing a balloon in the stomach by swallowing a capsule.

What is Intragastric Balloon?

Swallowable gastric balloon is a soft balloon that is placed in your stomach. It is first swallowable balloon that requires no surgery, endoscopy or anesthesia. Intragastric balloon is a bariatric procedure that helps achieve weight loss in combination with behavior change and diet compliance.

How is swallowable intragastric balloon placed?

The balloon is placed during a 20-minute consultation with your doctor.  You swallow a capsule that contains the deflated balloon. The capsule is attached to a thin tube. There is no need for surgery, endoscopy, or anaesthesia. A simple X-ray is used to make sure the capsule is in the right position.

Once the capsule is in your stomach, your doctor will use the tube to fill the balloon with liquid. You will have a second X-ray to confirm the balloon is filled and that the placement is complete. Your doctor will then gently remove the tube and you’ll be on your way. With the balloon in your stomach, you will be able to eat less food without feeling hungry.

After approximately 16 weeks inside your stomach, a time-activated release valve will open, allowing the balloon to empty and pass naturally through your digestive system (also known as your gastrointestinal tract) when you use the toilet. It’s a convenient and safe way to kick-start a healthier lifestyle. In rare cases, the empty balloon may be vomited, although startling, vomiting of the balloon has not been associated with any reported adverse events to date.
