Glomerulonephritis (GN) is inflammation of the glomeruli, which are structures in your kidneys that are made up of tiny blood vessels. These knots of vessels help filter your blood and remove excess fluids. If your glomeruli are damaged, your kidneys will stop working properly, and you can go into kidney failure.
Sometimes called nephritis, GN is a serious illness that can be life-threatening and requires immediate treatment. GN can be both acute, or sudden, and chronic, or long-term. This condition used to be known as Bright’s disease.
