Lupus (systemic lupus erythematosus) is a long-term condition that causes joint pain, skin rashes and tiredness. There's no cure, but symptoms can improve if treatment starts early.

Check if you have lupus

There are lots of possible symptoms of lupus.

The main symptoms include:

You might also have:

Symptom flare-ups

Lupus often flares up (relapses) and symptoms become worse for a few weeks, sometimes longer.

Symptoms then settle down (remission). The reason why symptoms flare up or settle down is not known.

Some people do not notice any difference and their symptoms are constant.

Non-urgent advice: See a GP if:

  • you often get symptoms of lupus

Lupus is better managed if it's found and treated early.

Tests for lupus

Lupus is not always easy to diagnose because the symptoms can be similar to other conditions.

A GP will usually do some blood tests. They may diagnose lupus if the tests show you have high levels of a certain type of antibody, and you also have the typical symptoms of lupus.

You might be referred for X-rays and scans of your heart, kidneys and other organs if the doctor thinks they might be affected.

If lupus is confirmed, you'll be advised to have regular checks and tests, such as blood tests to check for anaemia and urine tests to check for kidney problems.

Lupus can range from mild to severe
Severity How it affects the body

Immunosuppressant or biological medicines are sometimes used to treat severe lupus. They help to calm or control your body's immune system.

  • learn to pace yourself to avoid getting too tired

  • try to stay active, even on a bad day
