Glomerulonephritis

Overview

Glomerulonephritis is a type of kidney disease that involves the glomeruli — very small structures in the kidneys that supply blood to units in the kidneys that filter urine — called the nephrons. During glomerulonephritis, the glomeruli become inflamed and impair the kidney's ability to filter urine.

Glomerulonephritis can be acute (a sudden attack of inflammation) or chronic (coming on gradually).

Glomerulonephritis may develop after a bacterial infection, like strep throat, or it may be caused by a chronic condition.
