Glomerulonephritis is a group of diseases that cause inflammation of the tiny filters in the kidneys known as glomeruli. The primary role of the glomeruli is to remove excess fluid, electrolytes, and waste from the bloodstream and pass them into the urine. Inflammation of these filters can lead to varying degrees of kidney dysfunction and, if left untreated, can result in chronic kidney disease (CKD) or even kidney failure.
