R39: Other symptoms and signs involving the urinary system

R39.2: Extrarenal uraemia

The uric acid content in the blood can increase if the body creates additional uric acid or passes less uric acid. For example, your body will create a lot of uric acid if you drink a lot of alcohol or eat many purine-rich foods. The uric acid content can also increase if the urine cannot drain properly or the kidneys are no longer properly supplied with blood. When the kidneys are not working properly, harmful substances can also build up in the blood.

Having far too much uric acid and other harmful substances in the blood can damage the organs. This can cause diarrhea or the kidneys to stop working properly, for example. In that case, you may be seriously ill.
