What is glomerular disease?
- Your kidneys have about one million tiny filters called nephrons. Each nephron has a glomerulus, which you can see in the picture below. A glomerulus is a ball of tiny blood vessels that filter your blood. More than one glomerulus is called glomeruli. Glomeruli work like the strainers used in cooking. While blood moves through them, they let waste and extra water pass into the nephrons’ tubes to make urine. But at the same time, they hold back the protein and blood that your body needs.
- Glomerular disease can cause your glomeruli to leak blood or protein into your urine. Your urine may look pink or light brown from blood, or it may be foamy from protein.
