Glomerulosclerosis

What is glomerulosclerosis?

Glomerulosclerosis is the term used to describe scarring that occurs within the kidneys in the small balls of tiny blood vessels called the glomeruli. The glomeruli assist the kidneys in filtering urine from the blood.

What are the symptoms of glomerulosclerosis?

Early stages of glomerulosclerosis may not cause any symptoms. The most important warning sign of glomerular disease is proteinuria -- large amounts of protein in the blood -- which is usually discovered during a routine medical exam. However, the loss of large amounts of protein could cause swelling in the ankles or accumulation of fluid in the abdomen.

How is glomerulosclerosis diagnosed?

Scarring disrupts the filtering process of the kidneys allowing protein to leak from the blood into the urine.

Because glomerulosclerosis is just one of many possible causes of proteinuria, a kidney biopsy may be needed to determine if the cause is actually glomerulosclerosis. About 15 percent of people with proteinuria are diagnosed with glomerulosclerosis.

What causes glomerulosclerosis?

Glomerulosclerosis may develop in children or adults, and may result from different types of kidney conditions, as well as diabetes.

How is glomerulosclerosis treated?

Scarred glomeruli cannot be repaired. The best treatment for glomerulosclerosis depends upon what caused the scarring, as determined by a renal biopsy, the patient's condition, and his/her medical profile. A treatment protocol, as determined by a physician, may include any/all of the following:
