What is a Gastric Balloon

A Gastric Balloon is a non-surgical procedure that aims to control obesity by being placed in the stomach through the esophagus and giving the patient a full feeling. The balloon, made of silicone or polyurethane material, is placed in the stomach and inflated to a volume of 400-700cc using air or liquid. Patients who are not borderline obese, and struggle to lose weight with a healthy diet and exercise can opt for this method.

Types Of Gastric Balloon

Gastric balloons are divided into two: fixed volume balloons and adjustable gastric balloons. Fixed volume balloons remain in the stomach for 6 months and are removed at the end of this period via an endoscopy.

Fixed-volume balloons can be taken orally, and deflate on their own at the end of 4-6 months and are excreted through feces. The adjustable gastric balloon allows the volume of the balloon to be adjusted while in the stomach. These balloons are inflated between 400 – 700 cc after being placed in the stomach. Depending on the patient’s condition, the amount of fluid in the balloon can be increased or decreased. 

The recommended treatment may vary according to special conditions and the medical history of a patient.

The aim is to ensure that the patient notices the color during defecation in case of leakage. The application time is approximately 15-20 minutes. After the procedure, the patient is kept under observation for 1-2 hours as a precaution.

The duration of the balloon in the stomach varies according to the brand also. While the lifetime of some balloons is 6 months, this period can be up to 1 year for some. After the expiration of the effective period, the balloons are deflated and removed from the stomach by following the same steps.
