Polycystic kidney disease (PKD) is an inherited disorder in which clusters of cysts develop primarily within your kidneys, causing your kidneys to enlarge and lose function over time. Cysts are noncancerous round sacs containing fluid. The cysts vary in size, and they can grow very large. Having many cysts or large cysts can damage your kidneys.
Polycystic kidney disease also can cause cysts to develop in your liver and elsewhere in your body. The disease can cause serious complications, including high blood pressure and kidney failure.
PKD varies greatly in its severity, and some complications are preventable. Lifestyle changes and treatments might help reduce damage to your kidneys from complications.
