Lupus is a chronic autoimmune disease — meaning the immune system, which normally fights infection, turns against the body's own healthy tissue. It can cause inflammation and pain in almost any part of the body, including the skin, joints, kidneys, and heart.

Who Gets Lupus?

Anyone can develop lupus, but it is most common in women between the ages of 15 and 44. In fact, 9 out of 10 people with lupus are women. Certain racial and ethnic groups also face higher risk, including people who are African American, Asian American, Hispanic/Latino, Native American, or Pacific Islander. A family history of lupus or other autoimmune diseases can increase risk as well.

Types of Lupus

There are four types:

  • Systemic lupus erythematosus (SLE) — the most common form; affects multiple organ systems
  • Cutaneous lupus — limited to the skin
  • Drug-induced lupus — triggered by certain prescription medications
  • Neonatal lupus — a rare condition that can affect newborns of mothers who have lupus

Common Symptoms

Lupus symptoms vary widely from person to person, which can make it difficult to recognize. Some of the most common early signs include:

  • Extreme fatigue
  • Joint pain or swelling
  • A butterfly-shaped rash across the cheeks and nose
  • Skin rashes that worsen with sun exposure
  • Fever

Because lupus can affect so many parts of the body, no two people experience it the same way. A doctor is needed to properly evaluate symptoms and determine a diagnosis.

What Causes Lupus?

The exact cause is not fully known. Research suggests lupus may develop in response to a combination of hormonal factors (like estrogen), genetics, and environmental triggers — things outside the body that can bring on or worsen symptoms. Lupus is not contagious. You cannot catch it from another person.

Treatment and Management

There is no cure for lupus, but many people manage it effectively and live full, active lives. Treatment is typically guided by a doctor and may include medication to reduce inflammation, manage symptoms, and protect organs from damage. Avoiding known triggers — such as prolonged sun exposure, stress, and illness — can also help reduce flares.

When to See a Doctor

If you or someone you love is experiencing ongoing fatigue, unexplained joint pain, recurring rashes, or other persistent symptoms, talk to a doctor. Early diagnosis and consistent care make a significant difference in long-term health outcomes.
