Gastric balloons, like any medical procedure, come with certain risks. Some common risks of gastric balloons include nausea, vomiting, and stomach discomfort, especially during the initial adjustment period. There is also a small risk of balloon deflation or leakage, which may require balloon removal or replacement. In rare cases, gastric balloons can cause more serious complications such as blockage in the digestive system, stomach ulcers, or infection. It's important to discuss these risks with your healthcare provider and carefully follow their guidance throughout the process to minimize any potential complications.
