N18: Chronic kidney disease

N18.4: Chronic kidney disease, stage 4

Chronic kidney disease, stage 4, also known as severe kidney damage, is a serious health condition involving the progressive loss of kidney function. The condition often develops slowly with few symptoms in the early stages. As the disease advances to stage 4, the kidneys are no longer able to function effectively, which can lead to complications such as high blood pressure, anemia, weak bones, poor nutritional health, and nerve damage. The most common causes of chronic kidney disease are diabetes and hypertension. Depending on different factors, this condition may eventually lead to complete kidney failure, requiring dialysis or a kidney transplant for survival. It is vital to understand that this condition is usually not reversible, therefore proper management of underlying diseases and a healthy lifestyle can help to slow down its progression.
