How the Kidney works?

Kidneys are two bean-shaped organs located towards the back of the body on either side of the spine near the waistline

    • They are about the size of a fist approx. 12 cm long and weight around 180 gms. Other organs and two of the lower ribs protect them
    • Normal functioning Kidneys serve the body in several very important ways :
    • Clean your blood & remove toxic waste products such as urea & creatinine, the by-products of protein metabolism
    • Balance water and salt to control fluid in the body
    • Produce hormones that regulate blood pressure and volume
    • Make erythropoietin which stimulates bone marrow to make red blood cells which carry oxygen around
    • Produce Vitamin D which is important for healthy & strong bones
    • Control the amount of potassium, calcium, magnesium and phosphorous in the blood

In case of Kidney Failure , the kidenys are no longer able to excrete the toxic waste products into the urine. There are two types of Kidney Failure : 


Acute Kidney Failure

Occurs because of sudden trauma to the kidneys , the kidneys may stop working for a short while and then partially or fully recover.


Chronic Kidney Failure

Progressive condition whereby the kidneys become irreversibly damaged over a long period , often many years. This condition can develop because of an infection, diabetes , hypertension or inherited abnormalities. Advanced chronic renal failure is known as end stage Renal disease ( ESRD)
