We've rounded up all you need to know...

What is Lupus?

Lupus is an incurable immune system illness that affects many parts of the body including the skin, joints and organs. Lupus causes the immune system to produce too many antibodies, which may attack healthy tissues and leads to inflammation in the body. The symptoms can range from mild to life-threatening.

What are the symptoms of Lupus?

The symptoms of Lupus can develop over time and can vary from person to person, which means it is often difficult to diagnose. The main symptoms include fatigue, joint pain and swelling, and rashes – particularly on the face, wrist and hands.

Other symptoms may include a fever, swollen lymph glands, high blood pressure, headaches and migraines, depression, chest pain and memory loss, among others. According to the NHS, people may have long periods with few or no symptoms before experiencing a flare-up where their symptoms are more severe.

What is the treatment for Lupus?

There is no cure for lupus, but the symptoms can be managed with a mixture of medication and lifestyle changes. Non-steroidal anti-inflammatory drugs, such as ibuprofen, may help to reduce inflammation and ease joint and muscle pain. NHS recommends protecting skin from the sun, as this can sometimes make rashes worse. In more severe cases, sufferers may be prescribed Corticosteroids, which can bring symptoms under control and reduce inflammation quickly.
