The Allurion gastric balloon procedure, like any medical procedure, carries potential risks and side effects that should be considered. However, it is worth noting that with the newer version of the balloon, the risks of these side effects have significantly reduced. Some of the possible risks include nausea and vomiting in the initial days after balloon placement, abdominal pain and discomfort due to the presence of the balloon, the rare occurrence of balloon rupture or deflation which could lead to complications, potential irritation of the stomach lining or oesophagus, and the rare possibility of bowel blockage during the removal process. Allurion has a precautionary measure, a harmless dye called methylene blue is added when the balloon is filled during implantation. If the balloon were to rupture, this dye would cause your urine to turn green. In such cases, your healthcare professional would arrange for the balloon to be removed. It is important to discuss these risks with a healthcare professional and carefully evaluate whether the Allurion gastric balloon procedure is the right choice for your specific needs and medical history.
