Glomerulonephritis Glomerulonephritis (glow-mer-you-low-nef-RYE-tis), sometimes called glomerular disease, is a type of kidney disease in which the glomeruli (the tiny filters in your kidneys) are damaged and cannot remove waste and fluid like they should. If the glomerulonephritis is permanent and continues to get worse, this can lead to chronic kidney disease.
Polycystic kidney disease (PKD) Polycystic (polly-SIS-tick) kidney disease (PKD) is a genetic disease. PKD causes cysts to grow inside the kidneys. These cysts make the kidneys much larger than they should be and can damage the tissue that the kidneys are made of. PKD can cause chronic kidney disease.
IgA nephropathy IgA is a protein that helps you fight infections. In people with IgA nephropathy, these proteins build up and form clumps inside the kidneys’ tiny filters (glomeruli). These clumps of proteins damage the glomeruli. This damage can cause chronic kidney disease.
Lupus nephritis Lupus nephritis (nef-RYE-tis) is the medical name for kidney swelling and irritation that is caused by lupus. Lupus is an autoimmune disease. Autoimmune diseases cause your immune system to attack your own healthy cells. When your immune system attacks your kidneys, they get damaged. This damage can leave scars on the kidney. Over time, these scars can cause damage to the kidneys and can lead to chronic kidney disease.
Focal segmental glomerulosclerosis (FSGS) FSGS is the medical name for having scar tissue on your kidneys’ filters (glomeruli). For people with FSGS, the cause of the scars is often unknown. Over time, these scars can cause damage to the kidneys and can lead to chronic kidney disease.
Minimal change disease Minimal change disease is when there is damage to your kidneys’ filters (glomeruli). It is called minimal change disease, because the damage is so small, it can only be seen using a very powerful microscope. The cause of minimal change disease is unknown. The damage caused by minimal change disease can lead to chronic kidney disease.
