Intragastric Balloon: Discover What It Is, How It Works, and Much More

What is the intragastric balloon?

The intragastric balloon is a procedure that involves placing a balloon inside the stomach, occupying part of the available space, which causes the person to eat less.

Consequently, the intragastric balloon aids in the weight loss process.
 

How does the intragastric balloon work?

The intragastric balloon works by reducing the gastric capacity by up to 50% and making the passage of food more difficult, which slows down digestion a bit.

This sends a satiety signal to the brain, causing the patient to feel less hungry or the urge to eat at inappropriate times. It also helps people who suffer from food compulsion.

Important: the placement of the gastric balloon is considered an auxiliary treatment, meaning that in addition to being temporary (it can remain in the stomach for six or twelve months, depending on the type of balloon), it should be accompanied by a routine of healthier habits and dietary reeducation.

The gastric balloon is considered a less invasive approach compared to others (such as bariatric surgery) because it does not require surgery for placement and does not cause any metabolic changes.

Moreover, its efficiency helps in the control of diseases associated with obesity, such as hypertension and diabetes.

Is endoscopy required for the placement of the intragastric balloon?

Yes, endoscopy is performed as a preliminary examination to detect possible changes or abnormalities. If something is confirmed, treatment of the problem must be started before the balloon can be placed.

Is the placement of the intragastric balloon similar to an endoscopy exam?

Yes, the placement of the balloon can be compared to an endoscopy exam, as the intragastric balloon, still deflated, is inserted through the mouth, passing through the esophagus until it reaches the stomach.

To guide the way, an endoscope is used. The tube has a camera and light, which allow the doctor to watch the procedure simultaneously.

After the balloon’s time in the body, the doctor deflates and removes the gastric balloon. It is essential to respect the maximum period; otherwise, there is a risk of perforation due to deterioration of the material.
