Can you self diagnose lupus?

Lupus is a complex autoimmune disease that affects millions of people worldwide. The symptoms of lupus can vary greatly between individuals and over time, making it a challenge to diagnose. Some common symptoms include fatigue, joint pain or swelling, rashes, fever, and kidney problems. With such a broad range of possible symptoms, many people understandably wonder if they can diagnose lupus themselves before seeking professional medical advice.

What is Lupus?

Lupus is an autoimmune disease, meaning the immune system attacks healthy cells and tissues in the body by mistake. In lupus, the immune system is overactive and produces antibodies that target tissues and organs in the body. This can result in widespread inflammation and a wide array of symptoms. There are several types of lupus:

  • Systemic Lupus Erythematosus (SLE): The most common type, can affect any part of the body
  • Cutaneous Lupus: Affects the skin, causes rashes and lesions
  • Drug-induced Lupus: Caused by certain medications
  • Neonatal Lupus: A rare form that affects newborn babies of women with SLE

Women are more likely to develop lupus than men, with symptoms often beginning between ages 15-44. African Americans, Hispanics, Asians, and Native Americans are at higher risk as well. The exact causes are unknown, though both genetics and environment play a role. There is no cure, but symptoms can be managed with medications and lifestyle changes. Early diagnosis and treatment helps prevent complications.

Common Symptoms of Lupus

The symptoms of lupus vary from person to person and can come and go unpredictably. Almost any part of the body can be affected. Some of the most common symptoms include:

  • Fatigue
  • Joint pain, stiffness, and swelling
  • Muscle pain
  • Fever
  • Rash on cheeks and nose (butterfly rash)
  • Skin lesions that worsen with sun exposure
  • Chest pain when taking deep breaths
  • Dry eyes
  • Headaches and confusion
  • Anemia (low red blood cell count)
  • Kidney problems

Some people with lupus experience occasional flare-ups when symptoms suddenly worsen. Flare-ups can be triggered by infections, exposure to the sun, stress, certain medications, and excessive fatigue. Pregnancy can also cause complications for women with lupus.

Difficulty of Self-Diagnosis

With such a wide range of possible symptoms that can flare up and disappear, lupus is very difficult to self-diagnose. Many of the common symptoms mimick other illnesses like chronic fatigue syndrome, rheumatoid arthritis, fibromyalgia, and thyroid disorders. The unpredictable nature of lupus makes it hard for an individual to monitor their own symptoms objectively over time.

Some key reasons self-diagnosis of lupus is not advised:

  • Symptoms are vague, variable, and overlap with other conditions
  • There are no definitive diagnostic tests that can be self-administered
  • Lab tests require interpretation by a medical professional
  • Individuals may not recognize when symptoms represent a flair
  • The progression of symptoms over time is important
  • Detailed medical history and review of systems is required
  • A thorough physical exam by a doctor is an essential part of diagnosis
  • Self-monitoring for symptoms can be biased

Dangers of Self-Misdiagnosis

While wanting to figure out what might be causing your symptoms is understandable, self-misdiagnosing lupus can be dangerous. If you actually have another condition with similar symptoms, inappropriate treatment and delays in proper medical care could result in serious harm.

Some potential risks of self-misdiagnosing lupus include:

  • Trying unproven treatments or remedies
  • Worsening symptoms of the true underlying condition
  • Experiencing adverse effects from inappropriate medications
  • Progression to severe or irreversible complications
  • Additional stress and anxiety over perceived condition
  • Misinterpretation of lab tests without clinical context
  • Interference with appropriate diagnostic procedures
  • Delaying effective medical treatment and management

It is always best to seek an accurate diagnosis from a medical professional when experiencing new symptoms. While lupus can be difficult to identify, your doctor has the clinical knowledge and ability to take a complete history, perform a full examination, order and analyze tests, track symptom progression, and rule out other potential causes.

Diagnosing Lupus

So if lupus cannot be reliably self-diagnosed, how do doctors identify it? Diagnosing lupus can be challenging and involves reviewing a combination of factors over time. There is no single definitive test. Some of the key components of diagnosing lupus include:

  • Medical History: Looking for characteristic symptoms and flares, reviewing other existing conditions, and considering risk factors like family history.
  • Physical Exam: Identifying typical signs like rashes, joint swelling, and mouth sores. Helps rule out other causes.
  • Blood tests: Testing for autoantibodies related to lupus. These include antinuclear antibody (ANA), anti-doublestranded DNA, anti-Smith, and anti-phospholipid tests.
  • Urine tests: Checking for increased protein excretion or cellular casts that signal kidney involvement.
  • Imaging tests: X-rays, CT scans, or MRIs to assess possible organ damage or inflammation.
  • Skin biopsy: Removing a small sample of skin lesions to examine under a microscope.
  • Tracking progression: Monitoring symptoms over time to identify flare-ups and rule out other disorders.

Diagnosing lupus often requires analyzing subtle or vague symptoms and tying them together with clinical judgement based on medical expertise. Because the disease varies widely between patients, close monitoring over time is crucial, making self-diagnosis extremely difficult.

When to See a Doctor

If you experience any persistent symptoms associated with lupus, discuss them with your doctor as soon as possible. Early intervention greatly improves long term outcomes. Your physician can perform the necessary diagnostic steps and determine if you should be referred to a rheumatologist who specializes in autoimmune disorders like lupus.

Some signs and symptoms that warrant an urgent medical evaluation for possible lupus include:

  • Unexplained ongoing fever over 100°F (38°C)
  • Fatigue that interferes with your daily activities
  • Pronounced unexplained joint pain or swelling
  • Butterfly rash on cheeks and nose
  • Sores in the mouth or nose
  • Fingers or toes turning white or blue in the cold (Raynaud’s phenomenon)
  • Severe headache, confusion, seizures or vision changes
  • Shortness of breath or chest pain
  • Abdominal pain with vomiting
  • Ankle swelling, foamy urine, or dark urine

Pay attention to any symptom that lingers, worsens, or interferes with your normal functioning. Even if it ends up not being lupus, bring it to your doctor’s attention for proper diagnosis and treatment.

Diagnostic Criteria

Because no single test definitively confirms lupus, doctors use a specific set of diagnostic criteria to make a diagnosis. A patient must meet 4 out of 11 criteria from either the SLICC classification or ACR classification schemes below.

SLICC Classification Criteria

  • Acute or subacute cutaneous lupus
  • Chronic cutaneous lupus
  • Oral ulcers
  • Nonscarring alopecia
  • Synovitis or arthritis
  • Serositis (pleuritis or pericarditis)
  • Kidney disorder (proteinuria or cellular casts)
  • Neurologic disorder (seizures, psychosis)
  • Hemolytic anemia
  • Leukopenia or lymphopenia
  • Positive ANA

ACR Classification Criteria

  • Butterfly rash
  • Discoid lesions
  • Photosensitivity
  • Oral ulcers
  • Arthritis
  • Serositis (pleuritis or pericarditis)
  • Kidney disorder (proteinuria or cellular casts)
  • Neurologic disorder (seizures or psychosis)
  • Blood abnormalities
  • Immunologic phenomenon (positive ANA, anti-DNA, anti-Sm tests)

These classification systems help guide doctors toward an accurate lupus diagnosis. But determining which criteria a patient meets still requires medical interpretation of tests and clinical judgment.

Treatments

While there is no cure for lupus, various treatments can help control symptoms and minimize flare-ups. Working closely with your rheumatologist to find the right medication regimen is key. Some common treatments include:

  • NSAIDs to reduce inflammation and pain
  • Antimalarial drugs like hydroxychloroquine to suppress the overactive immune system
  • Corticosteroids like prednisone to decrease inflammation
  • Immunosuppressants to inhibit the overactive immune response
  • Belimumab to reduce autoantibody production
  • Blood thinners to reduce blood clot risk

Non-medication therapies like regular exercise, sun protection, stress reduction, and diet changes also play an important role. Treatment plans will be tailored to each patient’s specific symptoms and severity.

Coping with Lupus

Being diagnosed with lupus or any chronic illness can be emotionally challenging. Give yourself time to process and grieve the loss of your prior unaffected health. Joining lupus support groups can provide perspective from others going through similar struggles. Share your feelings openly with loved ones who can offer understanding and encouragement.

Prioritize rest when you feel fatigued. Let family and friends help out with household tasks during flares. Express your needs clearly at work and reduce obligations when necessary. Staying active when possible can boost mood and outlook. Managing stress well and getting psychological counseling if needed is also important.

Outlook

The long-term outlook for lupus varies. Many patients experience manageable symptoms with periods of remission. For some, lupus can cause severe organ damage and even life-threatening complications. However, early diagnosis and faithful treatment yields the best prognosis. Ongoing medical care is essential.

With support and shared knowledge, it is possible to live well with lupus. Be patient, communicate with your doctors, stick with your treatment plan, pay attention to warning signs, and maintain hope for future progress in therapies.

Key Points

  • Lupus has a wide range of symptoms that can mimic other illnesses, making self-diagnosis unreliable.
  • Seeking proper medical assessment as soon as symptoms appear gives the best chance for an accurate diagnosis.
  • Allowing lupus to go undiagnosed and untreated puts your health at serious risk.
  • Diagnosing lupus requires interpreting many factors and understanding how they interact, which takes clinical experience.
  • No single test can definitively diagnose lupus, but your doctor has the tools and expertise to make an accurate diagnosis.
  • Ongoing medical care and adherence to treatment helps control lupus symptoms and improve long-term health.

The Bottom Line

Suspecting you may have lupus based on your symptoms is understandable. However, self-diagnosing lupus is medically inadvisable due to the variability and vagueness of symptoms, risk of misinterpretation, and dangers of leaving another condition untreated. Always consult a doctor as soon as possible if you experience concerning or persistent symptoms. Your physician can perform the necessary clinical assessment and diagnostic steps to determine if you have lupus or another condition that requires care. With support and proper treatment, it is possible to manage your lupus symptoms, prevent serious complications, and live well.
