N18.1: Chronic kidney disease, stage 1
Your kidneys have had mild damage 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 blood pressure and the mineral levels in the blood, among other things.
When there is mild damage to the kidneys, it is known as early kidney disease. The kidneys can be damaged by long-term high blood pressure or elevated blood sugar, for example.
In the early stages of kidney disease, healthy areas of the kidneys can still ensure that kidney function is almost normally. Sufficient urine is still produced, for example. Therefore there are no or few symptoms. The urine may be paler than usual and foam up when urinating. You may also be thirstier than usual and have to urinate more frequently during the night. If the kidney disease gets worse, other symptoms can appear.
