It is far easier to manage your condition if you understand what kidneys do, what happens when they stop working as they should, and how treatments can replace the functions of normal kidneys.

The kidneys are two bean shaped organs situated on either side of the spine. They are responsible for filtering waste products and fluid from your blood.

Each kidney contains approximately one million nephrons. It is the nephron that is responsible for filtering and processing the blood that passes through, to form what we will eventually see as urine.

The kidneys will regulate the amount of fluid, and also the levels of electrolytes such as potassium, calcium and magnesium to ensure that levels within the blood remain stable. Waste products such as urea and creatinine are also filtered.

In addition, the kidneys also produce several hormones:

Erythropoetin, a hormone which ensures that red blood cells are produced
Renin, a hormone that regulates blood pressure
Vitamin D is also activated in the kidney, essential for ensuring that calcium is absorbed from food that we eat
