How Lupus can Affect Kidney (Renal) System?

Systematic Lupus erythematosus(SLE) or Lupus is an autoimmune disease which means that the immune system of a body starts attacking itself. It can affect any part of the body such as joints, skin, kidney, heart, lungs, blood, or brain.

The renal system of a person’s body is most likely to get affected by SLE or Lupus. Kidneys are part of the renal system which also includes two ureters, the bladder, and the urethra. The part of the kidney that is mostly affected by Lupus is a part of the nephron called glomerulus, a tuft of capillaries that functions to filter substances from the blood. That is why lupus can affect the inflammation of the nephrons is called glomerulonephritis. In the case of glomerulonephritis or lupus nephritis, lupus causes inflammation in the kidneys which leaves them unable to function properly for activities such as filtering waste from blood or removing access fluid from the body. If lupus nephritis is left untreated then it may cause permanent damage to kidneys or cause end-stage renal disease(ESRD).


Many pieces of research over the years have shown some causes that may play a part in lupus affecting the kidneys such as infections, viruses, toxic chemicals or pollutants, but there is no certain cause that doctors have come up with. Lupus nephritis most often occurs within the first five years in which lupus symptoms start showing. It usually affects the people within the age bracket of 20 to 40, and it is more common in women than in men, especially during child-bearing years. Thus, 90% of people diagnosed with lupus nephritis are women.

At the appearance of any of these symptoms, a person should get a proper diagnosis to identify the disease and get treatment at earliest.

  • Blood Tests

There are certain blood tests that help in diagnosing kidney damage or getting information about how well kidneys are filtering waste. The most common of these tests are a creatinine blood test and blood urea nitrogen (BUN) test which access the kidney function.

  • Kidney Biopsy

In kidney biopsy, a tiny piece of tissue is extracted from one of the kidneys, which is later examined under the microscope to check the inflammation caused by Lupus disease.


  • Corticosteroids and immunosuppressive drugs

One of the many ways of treating lupus nephritis is stopping the immune system from attacking glomerulus. These corticosteroids and immunosuppressive drugs are used to calm the immune system of the body and stop it from attacking the body.

  • Diuretics

Diuretics medicines are prescribed to lower blood pressure and get rid of the excess fluid and swelling in the body.

  • Diet Changes

It is important for a person to get proper treatment on time. If lupus nephritis is ignored for too long, it can cause permanent damage to kidneys or cause kidney failure. Thus, Choose any of the aforementioned treatment options to get rid of this disease at the earliest.
