What are the causes of Glomerulonephritis?
Glomerulonephritis may be caused by problems with the body's immune system. Often, the exact cause of glomerulonephritis is unknown. Damage to the glomeruli causes blood and protein to be lost in the urine. The condition may develop quickly and kidney function is lost within weeks or months (called rapidly progressive glomerulonephritis). A quarter of people with chronic glomerulonephritis have no history of kidney disease. </s>
