What is lupus?

Lupus is a chronic disorder that can affect your skin, joints, and internal organs. As an autoimmune disease, it triggers your immune system to attack healthy tissue, causing inflammation that can lead to serious problems over time, like kidney damage, cardiovascular disease, and other complications. Lupus can be hard to diagnose because symptoms vary between people and may mimic other diseases, but experienced providers can identify the disease and recommend a treatment plan.

Penn Medicine’s autoimmune disease care specialists are skilled at diagnosing and treating lupus. Our rheumatologists work with experts from a variety of disciplines to perform a thorough evaluation. After making a diagnosis, our experts create a care plan that can calm your symptoms and help protect your organs from damage. Lupus is manageable with the right therapies, and our specialists can get you the treatments that help you keep doing what you love.

Types of lupus

There are four types of lupus based on what parts of your body are affected and the cause of the disease. Your doctor can identify which type of lupus you have to create the best treatment plan.

Signs and symptoms of lupus

Symptoms of lupus depend on the areas of your body being affected by the disease. This may include your skin, joints, blood, kidneys, heart, or lungs. Lupus symptoms can be mild or severe enough to affect your daily life. You’re also likely to have periods when symptoms get worse, known as flares, and times when they go away, called remission.

Signs of lupus may include:

  • Joint or muscle pain
  • Skin rashes that get worse with sun exposure, including a rash in a butterfly shape across your cheeks and nose
  • Chest pain, including when you breathe deeply
  • White or blue fingers or toes when it’s cold or when you’re under stress, called Raynaud’s syndrome
  • Fever and fatigue
  • Headaches
  • Blood clots

Other lupus symptoms may include:

  • Shortness of breath
  • Swelling in your face, arms, legs, hands, or feet
  • Swollen glands
  • Hair loss
  • Confusion and memory loss
  • Sensitivity to light
  • Dry eyes

Lupus can also result in other health conditions, like heart disease, stroke, kidney disease, osteoporosis, anemia, seizures, and other health issues.

What causes lupus?

The cause of lupus isn’t exactly clear, but research has found that some things may trigger the onset of the disease.

Lupus symptoms may occur because of:

  • Certain gene changes, known as genetic mutations
  • Your body’s reaction to hormones, like estrogen
  • Environmental triggers, including air pollution, smoking cigarettes, infections, medications, and other factors in your environment

Lupus can be hereditary. It’s more common in people who have a family member with lupus or another autoimmune disease. The disease also occurs more often in people assigned female at birth and who are ages 15 to 44. Early signs of lupus in women can vary but may include swollen joints or fatigue. People of certain ethnic backgrounds are also more likely to have lupus, including African Americans, Asian Americans, Hispanics, Native Americans, and Pacific Islanders.

How is lupus diagnosed?

There’s no single test that can lead to a lupus diagnosis. Your doctor makes a diagnosis based on a combination of test results, your symptoms, and your family and personal medical history. You may need blood tests, urine tests, and a biopsy of your skin or kidney. Imaging tests can let your doctor know if your lungs or heart are affected.

Lupus treatment options

There’s no cure for lupus, but your health care team can create a treatment plan that helps relieve your symptoms and prevent flares. If lupus symptoms are caused by a drug you’re taking, your doctor can help you find another medication that won’t cause your symptoms. If you have SLE, cutaneous, or neonatal lupus, medications can lower your immune system response, helping to reduce your symptoms and protect your organs from damage. These medications may include oral drugs, skin creams, injections, and intravenous infusions. Often it takes a combination of drugs to manage lupus, and you may need treatment for complications, like heart disease or osteoporosis.
