Chronic Kidney disease (CKD)
Chronic kidney disease (CKD) is the slow loss of kidney function over time. It can be defined as the presence of kidney damage, or a decreased level of kidney function, for a period of three months or more. The main function of the kidneys is to remove waste and excess water from the body. Usually, chronic kidney disease starts slowly and
Chronic Kidney Disease can be divided into five stages, depending on how severe the damage is to the
The stages of CKD are:
Stage 1 – Kidney damage (protein in the urine) and normal GFR (>90)
Stage 2 – Kidney damage and mild drop in GFR (60–89)
Stage 3 – Moderate drop in GFR (30–59)
Stage 4 – Severe drop in GFR (15–29)
Stage 5 – Kidney failure: dialysis or kidney transplant needed (GFR <15)
|Stages 1 and 2 CKD||People with Stage 1 CKD have kidney damage with normal or high GFR greater than 90 ml/min. They generally do not experience any symptoms of kidney damage even if the kidneys are no longer functioning at full capacity. Most people are diagnosed with Stage 1 CKD in the process of being tested for another condition such as diabetes or high blood pressure, which are the two leading causes of kidney disease.|
|Stage 3||A person with Stage 3 CKD has kidney damage with a moderate decrease in the GFR of 30-59 ml/min. As kidney function declines, waste products and toxins begin to build up in the blood. Once toxins reach a certain level, uremia occurs and complications of kidney disease such as high blood pressure, anemia (a shortage of red blood cells) and/or early bone disease are more likely. At this stage of kidney
A person with Stage 4 CKD has advanced kidney damage with a severe decrease in GFR to 15-30 ml/min. It is likely someone with Stage 4 CKD will need dialysis or a kidney transplant in the near future.
As kidney function declines, waste products and toxins build up in the blood causing a condition known as “uremia.” At Stage 4, complications such as high blood pressure, anemia (a shortage of red blood cells), bone disease, heart disease and other cardiovascular diseases become more likely so it is important that people at Stage 4 CKD pay careful attention to their health.
|Stage 5||A person with Stage 5 CKD has
