Nephritis is inflammation of the kidney.
The two most common causes of nephritis are infection or an auto-immune process.
Nephritis has the effect of damaging and closing up the microscopic filters in the kidney.
This means that in addition to various toxic waste products, the inflamed kidney filters out important proteins (larger molecules) from the blood.
Therefore the characteristic symptom of nephritis is proteinuria - meaning the excessive removal of protein from the blood and its excretion in urine.
