**Glomerulonephritis** is a group of inflammatory diseases characterized by predominant damage to the glomeruli. Since the pathological process is not limited only to the glomerular zone, the inflammatory process also involves other parts of the nephron, up to atrophy and necrosis of the renal tubules.
Glomerulonephyrates are divided into primary, or idiopathic (there is no apparent reason for the development of the disease), as well as secondary, which arose against the background of various infections and other pathological conditions. In addition, acute, chronic glomerulonephritis and rapidly progressive glomerulonephitis are distinguished.
A separate group is glomerulonephthalic disorders, which are transient episodes of glomerular changes in the absence of other pathological signs of other organs of the urinary system.
These diseases can lead to serious health consequences, so it is important to consult a doctor promptly and begin treatment.
