N18.9: Chronic kidney disease, unspecified

Your kidneys are damaged. As a result, your kidney function may have been restricted for a long time.

There are normally 2 kidneys in the body. They filter blood and create urine. They thus help to detoxify the body. Furthermore, the kidneys regulate the blood pressure and salt content in the blood, among other things.

If the kidneys’ function is limited, they can no longer perform their tasks properly. This is also referred to as renal insufficiency. Kidney disease can develop as a result of long-term high blood pressure or elevated blood sugar, for example.

If the kidneys are only working to a limited degree, harmful substances can accumulate in the body. The blood pressure or the levels of particular substances in the blood may also change. This can have many effects in the body. It may also be that the kidneys are working more poorly with no apparent problems.

  • V: Tentative diagnosis
  • Z: Condition after
