N18.1: Chronic kidney disease, stage 1
Your kidneys are damaged. Your kidneys may no longer work properly.
This is also referred to as renal insufficiency.
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 are no longer working properly, they can no longer perform their tasks properly. One result of this may be that your blood pressure is too high. If the kidneys stop producing enough urine, you excrete little urine. Too much fluid then remains in the body. This fluid can then collect in the legs, for example.
The kidneys also produce messenger substances. If the kidneys no longer work properly, not enough messenger substances are produced. This can impact on the body in many ways. For example, the bones may become less solid. Not enough of the red blood pigment may be produced. The salt content and acid content in your blood may also change. Deposits may also form more rapidly in the blood vessels.
If the kidneys no longer work properly, substances can also collect in the body. These substances are normally excreted in the urine. The body can be damaged by these substances.
