Interstitial Nephritis | Overview


What is interstitial nephritis?

Interstitial nephritis (say: in-ter-stih-shul nef-rye-tus) is a kidney disorder. The kidneys filter waste and extra fluid from the body. Interstitial nephritis reduces the kidneys’ ability to filter properly.

Interstitial nephritis is a serious condition, but it can be treated. However, in rare cases, it may cause kidney failure. When the kidneys fail, waste and extra fluid build up in the body and can cause problems with the heart, brain, lungs and other organs.
