Glomerulonephritis is a type of kidney disease that involves inflammation of the glomeruli, which are the tiny filters in the kidneys responsible for removing waste and excess fluid from the blood to form urine. This inflammation can lead to damage of the glomeruli and impair the kidney's ability to function properly. Glomerulonephritis can be caused by a variety of factors, including infections, autoimmune disorders, and genetic predispositions. Common symptoms include blood or protein in the urine, swelling in the hands and feet, high blood pressure, and fatigue. Treatment for glomerulonephritis typically involves managing symptoms, controlling blood pressure, and addressing the underlying cause of the disease.
