The likelihood of a gastric balloon leaking, deflating, or "bursting" is generally considered very low or a rare occurrence. However, understanding potential complications like a leak or deflation is crucial for all patients.
To detect a leak, the saline fluid inside the balloon contains a blue dye (like Methylene Blue). If the balloon leaks, the dye is absorbed by the body, and you will notice a sudden change to blue or green coloured urine (and/or stools).
If you notice the colour change, get in touch with your specialist for further intervention.
