Lupus is an autoimmune disease, which means that the body’s immune system attacks healthy cells and tissues by mistake.

Normally, the immune system protects the body from infection and illness. But in people with lupus, the immune system doesn’t work properly. It may overreact or underreact to certain situations.

Lupus can cause inflammation and tissue damage throughout the body. Symptoms of lupus can vary from mild to life-threatening and may include joint pain, rash, fever, and kidney problems.

Experts don’t know what causes lupus. But they have found that some things can trigger the disease or make it worse. These include infection, certain medications, stress, and sunlight. People with a family history of lupus are also more likely to develop the condition.

There is no cure for lupus, but treatments can help manage symptoms and reduce inflammation. Common treatments include medication, lifestyle changes, and self-care measures. Medications used to treat lupus include corticosteroids, antimalarial drugs, and immunosuppressants.

Lifestyle changes can help manage lupus symptoms and flare-ups. These include getting enough rest, reducing stress, and avoiding triggers like sunlight and infection.

Self-care measures can also help, such as using sunscreen and taking steps to avoid infections.
