The first week after the operation, it is recommended to consume liquid food. A tender diet is recommended for the next two weeks. After a month, the user can already eat all kinds of food.
Therefore, it is possible to lose between 3 and 20 kg, but the ball does not have a long-term effect on the stomach. Don’t look at the number of pounds lost. The relevance of this device is measured by the patient’s ability to maintain their weight stabilized over time.. Long-term results strongly depend on the patient’s lifestyle.
Weight loss will continue if the patient adopts the same eating habits and behaviors that led to weight loss, even after balloon removal. The continuation of the follow-ups will facilitate the adoption of a healthy lifestyle conducive to the reduction of extra kilos.

What happens to the gastric balloon once you have lost weight?
After its time limit, the ball must be removed and discarded. It is no longer effective, because the stomach has become accustomed to it. Removal of a polyurethane balloon is ideally done 4-6 months after installation, depending on the device used. The silicone balloon lasts longer, up to 12 months. Beyond the limit, the gastric balloon disintegrates under the action of hydrochloric acid in the stomach and is evacuated through natural pathways.
A residue-free diet and medications that can stimulate stomach movement are prerequisites for balloon removal. The operation is performed by endoscopy using a kit that contains a catheter, a puncture needle and tweezers. The contents of the balloon are aspirated before its extraction. The stomach then returns to its original shape before deposition.
The ball pose should not be seen as a miracle technique to lose weight. Maintaining an ideal weight over time after balloon installation requires a personal commitment to a healthier lifestyle.
