Overview

Glomerulonephritis (say "gluh-mair-yuh-loh-nih-FRY-tus") is inflammation of the many tiny filters in your kidneys (glomeruli). A glomerulus is a cluster of blood vessels that filters fluid and waste from your body as urine.

Depending on the cause of the inflammation, you may not have any symptoms. Or you may have foamy urine, high blood pressure, or swelling in your face, feet, or hands.

Glomerulonephritis can be caused by an infection or some medicines. It can be caused by diseases like diabetes or lupus. Sometimes the cause is not known.

This illness may get better with treatment. But it often leads to long-term (chronic) kidney disease.

Treatment may include:

• Corticosteroid medicines. These reduce inflammation.
• Immunosuppressive medicines. These reduce inflammation.
• One or more medicines to lower your blood pressure.
• Dialysis, in some cases. This is a treatment that does the work for your kidneys to filter waste from your blood.

How can you care for yourself at home?

• Take your medicines exactly as prescribed. Call your doctor or nurse advice line if you have any problems with your medicine. You will get more details on the specific medicines your doctor prescribes.
• A dietitian can help you make an eating plan with the right amounts of salt (sodium), potassium, and protein. You may also need to limit how much fluid you drink each day.
• Do not take anti-inflammatory medicines such as ibuprofen (Advil, Motrin) and naproxen (Aleve). They can make kidney problems worse. It is okay to take acetaminophen (Tylenol).
• Seek support from family, friends, and a counsellor if you need it. Long-term illnesses can be difficult and stressful.
