Glomerulonephritis is inflammation of the glomeruli, the tiny filtering units of the kidneys. It can be caused by infections, autoimmune diseases, or conditions like diabetes and high blood pressure. This condition impairs the kidneys' ability to filter waste and excess fluids, leading to complications such as high blood pressure, fluid retention, and kidney failure. Treatment depends on the cause but often includes medications to control symptoms, reduce inflammation, and protect kidney function. t can be acute (sudden) or chronic (long-term), depending on the cause and severity.
