Understanding Kidney Disease
There are Five Stages of Kidney Disease
Stage 1 - Normal kidney function but you are already known to have some kidney damage or disease. i.e. you may have some protein or blood in your urine, an abnormality of your kidney,
Stage 2 - Mildly reduced kidney function AND you are already known to have some kidney damage or disease.
Stage 3 - Moderately reduced kidney function. (May not have a known kidney disease. i.e. an elderly person with ageing kidneys may have reduced kidney function without a specific known kidney disease.)
Stage 4 - Severely reduced kidney function. (May not have a known kidney disease.)
Stage 5 - A very severely reduced kidney function. This is sometimes called end-stage kidney failure or established renal failure.
You have two Kidneys, these are located both sides of your spine, and just above your waist.
Each kidney is about the size of a large orange, but bean-shaped.
What Your Kidneys Do
Kidneys remove waste products from your blood, which are passed out as urine.
They keep a balance of water and minerals like sodium, potassium, and phosphorous in your blood.
They help control your blood pressure
They make a chemical called erythropoietin, which stimulates the bone marrow to make red blood cells
They make an active form of vitamin D, needed for bone health and other things
