Lupus: Symptoms, Causes, and Treatment

Lupus is an autoimmune disease that causes inflammation in various parts of the body. It most often affects women between ages 15-44. Symptoms vary widely but may include fatigue, joint pain, and a distinctive butterfly-shaped face rash. While there's no cure, treatments can help control symptoms and prevent complications.

In plain words

Lupus is a disease where your body's defense system attacks your healthy cells by mistake. It can cause problems in different parts like your skin, joints, and organs. Most people who get lupus are women between 15 and 44 years old. Signs can include feeling very tired, joint pain, and a special rash on the face shaped like a butterfly. There is no cure, but treatments can help control symptoms and prevent serious damage.

What is Lupus: Symptoms, Causes, and Treatment?

Lupus is an autoimmune disease that causes inflammation in various parts of the body. It most often affects women between ages 15-44. Symptoms vary widely but may include fatigue, joint pain, and a distinctive butterfly-shaped face rash. While there's no cure, treatments can help control symptoms and prevent complications.

Symptoms

Early symptoms

  • Butterfly-shaped face rash: A red, butterfly-shaped rash across the cheeks and nose (malar rash) is a hallmark symptom. It may be flat or raised and often gets worse with sun exposure. (2) (6)
  • Joint pain and swelling: Pain, stiffness, and swelling in joints, often affecting hands, wrists, and knees. Morning stiffness is common and may come and go. (3) (6)
  • Extreme fatigue: Persistent tiredness that isn't relieved by rest. This is one of the most common symptoms and can be debilitating even when other symptoms are mild. (2) (6)
  • Sun sensitivity: Skin rashes that develop or worsen after sun exposure. Some people experience systemic symptoms like fatigue and joint pain after being in the sun. (2) (6)
  • Unexplained fever: Low-grade fevers (under 101°F) that come and go without any obvious infection being present. (5) (6)
  • Hair loss: Patchy hair loss or thinning, sometimes following periods of stress or disease activity. Hair may become brittle or break easily. (5) (6)

Serious or emergency symptoms

  • Chest pain with deep breathing: Pain when taking deep breaths, which may indicate inflammation of the lining around the heart or lungs (pleurisy or pericarditis). Seek medical attention if this symptom develops suddenly. (2) (6)
  • Kidney problems: Swelling in legs/feet, foamy urine, or high blood pressure may signal lupus nephritis (kidney inflammation). Early treatment is crucial to prevent permanent damage. Contact your doctor immediately if you notice these symptoms. (6)
  • Neurological symptoms: Severe headaches, seizures, confusion, or personality changes could indicate central nervous system involvement. Get immediate medical help for any new severe neurological symptoms. (6)
  • Blood abnormalities: Signs of anemia (extreme fatigue, pale skin), easy bruising/bleeding, or frequent infections that may indicate low blood cell counts. Report significant changes in your energy levels or bruising to your healthcare provider. (6)

Causes

Primary causes

  • Autoimmune dysfunction: Lupus occurs when the immune system mistakenly attacks the body's own tissues. The exact reason this happens isn't fully understood. (1) (6)
  • Genetic predisposition: Certain genes increase lupus risk, but having these genes doesn't guarantee you'll develop the condition. About 10% of people with lupus have a relative with it. (6)
  • Environmental triggers: Potential triggers include sunlight, infections, certain medications, and stress. These may activate lupus in genetically susceptible people. (1) (6)

Risk factors

Being female

Women, especially those of childbearing age (15-44), account for about 90% of lupus cases. Hormonal factors likely play a role. (6)

Certain ethnic backgrounds

Lupus is more common and often more severe in African-American, Hispanic, Asian, and Native American populations. (6)

Family history

Having a close relative with lupus or another autoimmune disease increases your risk. (6)

Certain medications

Some blood pressure medications, anti-seizure drugs, and antibiotics can trigger drug-induced lupus, which usually resolves after stopping the medication. (6)

Diagnosis

Diagnosing lupus can be challenging as symptoms often mimic other conditions. Doctors typically use a combination of physical exam findings, medical history, and various tests including blood tests (like the ANA test), urine tests, and sometimes imaging studies or biopsies. A rheumatologist (arthritis specialist) usually makes the diagnosis based on established criteria that evaluate symptoms and test results. Since symptoms can develop slowly, it may take time to reach a definitive diagnosis.

Antinuclear antibody (ANA) test

Most people with lupus test positive for ANAs, though a positive result doesn't always mean lupus. This is usually the first screening test. (4) (7)

Complete blood count

Checks for anemia, low white blood cell count, or low platelet count, which are common in lupus. (4) (7)

Erythrocyte sedimentation rate (ESR)

Measures inflammation levels in the body, which are often elevated in lupus flares. (7)

Urinalysis

Checks for kidney problems by looking for protein or blood cells in urine. (4)

Treatment

Medication options

Antimalarial drugs

These help control mild lupus symptoms, especially skin and joint problems, and may prevent flares. Also helps with fatigue and may have protective effects on organs. (7) (5)

Nonsteroidal anti-inflammatory drugs (NSAIDs)

Help reduce pain, fever, and inflammation. Used for mild lupus symptoms like joint pain and swelling. (7) (5)

Corticosteroids

Powerful anti-inflammatory medications that can quickly control severe lupus symptoms during flares, especially when internal organs are affected. (7)

Immunosuppressants

Used for severe lupus to suppress the overactive immune system, especially when kidneys or other major organs are involved. (7)

Lifestyle and self-care

  • Sun protection: Use broad-spectrum sunscreen (SPF 50+) daily, wear protective clothing, and avoid midday sun since UV light can trigger lupus flares. (8)
  • Stress management: Practice relaxation techniques like meditation, gentle yoga, or deep breathing as stress can trigger symptom flares. (8)
  • Regular rest: Balance activity with periods of rest to manage fatigue. Pay attention to your body's signals and don't overdo it. (8)
  • Healthy diet: Eat a balanced diet rich in fruits, vegetables, whole grains, and lean proteins. Some evidence suggests omega-3 fatty acids (in fish) may help reduce inflammation. (8)
  • Smoking cessation: Smoking can worsen lupus symptoms and reduce medication effectiveness. Quitting can significantly improve your condition. (8)

Always discuss dosing and treatment changes with your own prescriber.

Possible complications

  • GAP: Complications not covered in evidence dossier: Information about lupus complications was not found in the current research sources.

When to see a doctor

Routine follow-up

  • Schedule an appointment if you experience persistent symptoms like fatigue, joint pain, or unexplained rashes that might indicate lupus. (3) (6)
  • If you have lupus, maintain regular follow-ups with your rheumatologist even when feeling well to monitor disease activity and medication effects.

Seek emergency care

  • Seek immediate medical care for chest pain with breathing, severe headache, seizures, confusion, or sudden changes in vision as these could indicate serious lupus complications. (6)
  • Get urgent care for signs of infection if you take immunosuppressant medications, as you may be at higher risk for serious illness.

Frequently asked questions

What is Lupus?

Lupus is a chronic autoimmune disease where the immune system mistakenly attacks healthy tissues. It can affect multiple parts of the body including joints, skin, kidneys, blood cells, brain, heart and lungs. The most common type is systemic lupus erythematosus (SLE). While symptoms vary widely between people, common signs include fatigue, joint pain, and skin rashes. (1) (3)

What are the first signs of Lupus?

Early signs often include extreme fatigue, joint pain or swelling, a butterfly-shaped rash on the face, and unexplained fever. Many people first notice they feel unusually tired or get skin rashes, especially after sun exposure. Symptoms typically come and go in periods called flares. (2) (6)

What causes Lupus?

The exact cause isn't known, but lupus appears to result from a combination of genetic predisposition and environmental triggers like sunlight, infections, or stress. Being female is the strongest risk factor, with most cases occurring in women of childbearing age. Certain medications can also cause a form of lupus that usually resolves when the drug is stopped. (1) (6)

How is Lupus treated?

Treatment focuses on controlling symptoms and preventing organ damage. Medications may include antimalarial drugs for mild cases, NSAIDs for pain/swelling, corticosteroids and immunosuppressants for severe disease. Lifestyle approaches like sun protection, stress management, and regular rest are also important. Your doctor will create a personalized treatment plan based on your symptoms. (7) (5)

Can Lupus be cured?

Currently there's no cure for lupus, but treatments can help control symptoms and allow people to live active lives. Many experience periods of remission with few or no symptoms. With proper management, most people with lupus now have a normal lifespan. Ongoing research continues to improve treatment options. (3) (5)
