Guide To The Causes Of Blood In Urine (Hematuria)

Glomerulonephritis

Glomerulonephritis is the inflammation of the tiny kidney filters called glomeruli. It has numerous causes, including viral infection, bacterial infection, lupus, Goodpasture's syndrome, IgA nephropathy, vasculitis, high blood pressure, glomerulosclerosis, and diabetes. Glomeruli are made out of numerous knots of tiny blood vessels that utilize homeostatic processes to extract excess fluid and waste substances from the blood. The more glomeruli that are affected by inflammation, the greater the amount of tissue damage and more of a decrease in kidney function. Glomerulonephritis can occur as an acute condition or as a chronic condition. Gross hematuria that turns the urine a dark red rust color is more likely to occur in individuals who are affected by acute glomerulonephritis, while microscopic hematuria is more likely to occur in chronic glomerulonephritis.
