What is Focal Segmental Glomerulosclerosis (FSGS)?
Focal Segmental Glomerulosclerosis (FSGS) is a type of glomerular disease that causes scarring (sclerosis) in parts of the kidneys called glomeruli, which are responsible for filtering blood to form urine. The term "focal" means that some, but not all, glomeruli are affected. "Segmental" indicates that only a portion of an individual glomerulus is involved.
