What is SLE?

SLE, or Systemic Lupus Erythematosus, is a long-term autoimmune disease. In SLE, the immune system attacks healthy tissues by mistake. As a result, this can cause swelling, pain, and damage in many parts of the body. SLE can affect the skin, joints, kidneys, heart, lungs, and brain. Although anyone can get SLE, it is more common in women, especially those aged 15 to 45. According to the CDC, SLE is more common in certain ethnic groups, such as African Americans, Hispanics, and Asians.

Common Symptoms of SLE

Because SLE can affect many organs, symptoms may vary. However, some signs are more common than others. Early detection of SLE symptoms can help with better management. Watch for these signs:

  • Fatigue or feeling very tired
  • Joint pain and swelling
  • Skin rashes, especially a butterfly-shaped rash on the face
  • Fever without a clear cause
  • Hair loss
  • Sun sensitivity
  • Mouth or nose sores
  • Chest pain when taking deep breaths
  • Swelling in the legs or around the eyes
  • Sometimes, symptoms come and go. For example, you may feel fine for weeks, then have a flare-up. Because SLE symptoms can look like other illnesses, it is important to see a doctor for a proper diagnosis.

    Causes and Risk Factors

    Doctors do not know the exact cause of SLE. However, several factors may increase your risk. These include:

  • Genetics: Family history of SLE or other autoimmune diseases
  • Hormones: SLE is more common in women, suggesting hormones play a role
  • Environment: Sunlight, infections, or certain medicines may trigger SLE in some people
  • Ethnicity: Higher risk in African American, Hispanic, Asian, and Native American groups
  • Even though these factors increase risk, not everyone with them will get SLE. Sometimes, SLE develops without any clear reason.

    How SLE is Diagnosed

    Diagnosing SLE can be challenging. This is because symptoms often mimic other diseases. Still, doctors use several steps to make a diagnosis:

  • Medical history and physical exam
  • Blood tests, such as ANA (antinuclear antibody) test
  • Urine tests to check for kidney problems
  • Imaging tests, like X-rays or ultrasounds, if needed
  • Skin or kidney biopsy in some cases
  • Doctors may use guidelines from the American College of Rheumatology to help confirm SLE. Early SLE diagnosis is important for better outcomes.

    Treatment Options for SLE

    While there is no cure for SLE, treatment can help control symptoms and prevent damage. Treatment plans depend on your symptoms and which organs are affected. Common SLE treatment options include:

  • Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain and swelling
  • Antimalarial drugs, such as hydroxychloroquine, for skin and joint symptoms
  • Corticosteroids to reduce inflammation
  • Immunosuppressive medicines for severe cases
  • Biologic drugs for patients who do not respond to other treatments
  • Because SLE treatment can have side effects, regular doctor visits are important. Your doctor will adjust your treatment as needed.

    Lifestyle Tips for Living with SLE

    In addition to medicines, healthy habits can help you live better with lupus. Try these tips for living with SLE:

  • Get enough rest and pace yourself
  • Eat a balanced diet rich in fruits and vegetables
  • Exercise regularly, but avoid overdoing it
  • Protect your skin from the sun by wearing hats and sunscreen
  • Manage stress with relaxation techniques
  • Stay up to date with vaccines and regular check-ups
  • With support from family, friends, and your healthcare team, you can manage SLE more easily.

    Prevention and Early Detection

    Currently, there is no known way to prevent SLE. However, early detection and treatment can help reduce flares and organ damage. If you have a family history of SLE or notice symptoms, talk to your doctor. Regular check-ups can help catch problems early. In some areas, local support groups and clinics offer resources for people living with lupus.

    When to See a Doctor

    If you notice symptoms like ongoing fatigue, joint pain, or skin rashes, see a doctor soon. Early diagnosis and treatment of SLE can help prevent serious problems. Even if your symptoms seem mild, it is better to get checked. For ongoing care, a rheumatologist is the specialist who treats SLE.
