Insertion of Intra-Gastric Balloon


What is a gastric balloon?

This is a balloon inserted into your stomach either by swallowing it, or requiring insertion under guidance with a gastroscopy.

Depending on the balloon used, the balloon can stay within the stomach for 4 to 12 months duration. After which, the balloon can either be passed out by itself via the alimentary tract, or require a gastroscopy to retrieve the balloon.

How do you insert this intra-gastric balloon?

​There are 2 types of intra-gastric balloon. The Allurion Elipse is a swallowable balloon that do not require gastroscopy guided insertion. There are other gastric balloons that requires gastroscopy guided insertion, and they have been approved for a longer duration within the stomach.

Gastric balloon removal

Some types of gastric balloon will require a gastroscopy to remove it from the body. The intra gastric balloon is deflated, grabbed and removed with a grasper passed down the gastroscope. The Allurion Elipse balloon will self-deflate after its scheduled time. It will then be passed out of the body.

What are the benefits of the procedure?

Depends on the type of balloon used, it can stay for a period of 4 months to 12 months.

Can it be removed earlier?

Yes. While most patients are able to tolerate the balloon within the stomach to achieve the maximum weight loss effect, a minority of patients may not be able to tolerate and request for the intra-gastric balloon to be removed early. This can be done with gastroscopy and is a day procedure, meaning you do not need to stay in hospital overnight.
