Lupus is a chronic autoimmune condition that can affect various systems and areas of the body. It often impacts the skin, and historically, it was named "Lupus" (Latin for "wolf") due to skin rashes resembling wolf bites. Today, many lupus cases involve some type of skin rash, but the condition can also affect the kidneys, joints, brain, heart, and immune system.

Types of Lupus
Lupus has four main types, each classified by the area of the body involved. SLE (Systemic Lupus Erythematosus) is the most common type, contributing to a significant portion of lupus cases.
Other types of Lupus:
- Cutaneous lupus erythematosus
- Drug-induced lupus erythematosus
- Neonatal Lupus
This disease can be challenging to diagnose as its symptoms overlap with other autoimmune conditions. Even with its distinctive butterfly rash (or malar rash), only some lupus cases will exhibit this.
Some individuals experience significant challenges with Lupus, while others may have milder symptoms. Many patients face unpredictable flare-ups and may spend years seeking an accurate diagnosis.
Conventional medicine can help manage symptoms through pain relievers, steroids, and hormone replacement. A holistic approach, including diet, exercise, and supplements, may offer additional support for overall well-being.
Signs and Symptoms of Lupus
Lupus is sometimes called "the great imitator" because it can mimic symptoms of other conditions such as fibromyalgia, Lyme disease, and thyroid issues. Patients often experience flares and remissions, making diagnosis challenging. A study by the Lupus Foundation of America found that many individuals with lupus report being misdiagnosed or told their symptoms were psychological.
Lupus symptoms can vary widely and may include:
- Chronic fatigue
- Joint pain and stiffness
- Swelling or edema
- Muscle pain
- Shortness of breath
- Chest pain
- Headaches
- Unexplained fever
- Skin rashes
- Malar ("butterfly") rash
- Photosensitivity (sensitivity to light)
- Vision disturbances (blurry vision, dry eyes)
- Brain fog and memory loss
- Anemia
- Mouth sores
- Digestive problems
Additionally, lupus can impact mental-emotional health, potentially leading to feelings of depression or anxiety. Systemic inflammation from lupus may also be associated with sleep disturbances. Raynaud's phenomenon, where extremities change color in response to cold, may also occur with lupus.
What Causes Lupus?
The exact cause of lupus is not fully understood, but it is believed to involve a combination of genetic and environmental factors. Research suggests that certain genes may increase susceptibility to lupus, and environmental triggers may play a role in its development.
Genetics
There are several genes associated with lupus, and while no single gene is responsible, genetics are thought to contribute to the condition.
Environment
Research has not yet identified a specific environmental trigger for lupus. However, it is hypothesized that individuals with a genetic predisposition may develop lupus after exposure to certain environmental factors. Potential triggers include:
- Sunlight: UVA and UVB waves may trigger or exacerbate lupus symptoms.
- Infections: Certain viruses, such as EBV, CMV, and HERVs, are thought to be associated with lupus.
- Medications: Some pharmaceuticals are known to trigger drug-induced lupus.
Risk Factors of Lupus
- Sex: Women are more likely to develop lupus than men.
- Age: Most cases are diagnosed between the ages of 15 and 44.
- Race/ethnicity: Lupus is more common in individuals of African American, Hispanic/Latino, Asian American, Native American, Native Hawaiian, or Pacific Islander descent.
- African American women are more likely to develop lupus compared to Caucasian women.
Drug-Induced Lupus
Drug-induced lupus erythematosus is a type of lupus triggered by certain medications. While its symptoms are similar to SLE, it is classified separately due to its specific trigger. Generally, discontinuing the medication resolves the symptoms.
Common drugs associated with drug-induced lupus include:
- Hydralazine: used for hypertension
- Procainamide: used for arrhythmias
- Isoniazid: used for tuberculosis
- Minocycline: used for acne
- Anti-TNF: used for rheumatoid arthritis, psoriatic arthritis, spondyloarthropathy
Complications of Lupus
- Lupus can affect the kidneys, leading to a condition called lupus nephritis, which may cause symptoms like swelling, high blood pressure, and kidney issues.
- When lupus affects the brain, it may cause headaches, dizziness, behavior changes, vision changes, strokes, seizures, memory loss, or difficulty expressing oneself.
- Inflammation from lupus can impact the cardiovascular system, potentially leading to anemia, blood clots, or increased bleeding. It may also increase the risk of heart disease.
- Lupus-related inflammation can affect the lungs, making breathing difficult or painful and may lead to conditions like pneumonia.
- As an autoimmune condition, lupus can lead to imbalances in the immune system, increasing the risk of infections and slightly increasing the risk of cancer.
- Lupus can also affect bone health and may impact pregnancy, potentially leading to complications like miscarriage or pre-term birth.
How is Lupus Diagnosed?
Doctors use a combination of medical history, family history, laboratory tests, and physical exams to diagnose lupus and rule out other disorders.
Many people with lupus test positive for ANA, but a positive ANA does not always indicate lupus. If ANA is positive, further tests for antibodies specific to systemic lupus erythematosus may be conducted.
Labs helpful in diagnosing Lupus
- Autoantibodies are important in testing for lupus and can help confirm a diagnosis or identify other autoimmune conditions.
- CBC checks for anemia and immune function.
- CMP tests for kidney and liver function.
- ESR and CRP measure inflammation levels in the body.
- Biopsy of the affected area (e.g., rash or kidney) can show signs of an autoimmune disease.
Conventional Treatment for Lupus
Currently, there is no cure for lupus. Treatment focuses on managing symptoms and preventing further damage. Medications aim to reduce pain and swelling, calm the immune system, and protect joints and organs.
Depending on the areas affected, treatment may involve multiple specialists. Lupus can occur alongside other autoimmune conditions, requiring additional treatments.
Commonly Used Treatments for Lupus
- Anti-malarials may help with joint pain, rashes, fatigue, and lung inflammation.
- NSAIDs can assist with mild pain and swelling.
- Corticosteroids reduce pain and swelling and calm the immune system.
- BLyS-specific inhibitors target abnormal B cells in the immune system.
- Synthetic hormones or birth control pills may help regulate certain symptoms.
Supportive Approaches for Lupus
Nutrition
A diet focusing on whole foods, omega-3 fatty acids, and antioxidants from a variety of fruits and vegetables may support overall health in individuals with lupus. Reducing processed foods, sugar, and gluten may also be beneficial.
If you have lupus nephritis, you may need to adjust your diet. Consulting a registered dietitian can provide personalized guidance.
Oral Hygiene
Maintaining a balanced oral microbiome is important for overall health. Research suggests that oral health may be particularly relevant for individuals with lupus. Good oral hygiene and gut microbiome support may be beneficial.
Supplements
Turmeric may offer support for managing inflammation and promoting immune balance. It is important to discuss any supplement use with a healthcare provider.
Green tea extract (ECGC) may have supportive effects on immune function and inflammation. Studies suggest it may help improve quality of life for some individuals with lupus.
Vitamin D is often discussed in the context of immune health and may support mood balance. Consulting with a healthcare provider can help determine appropriate use.
DHEA may be considered for supporting symptom management, but testing adrenal health and DHEA levels is recommended before use.
Lifestyle
Prioritizing sleep, regular exercise, avoiding smoking, and practicing relaxation techniques may help manage stress and support overall well-being.
Summary
Lupus is a chronic autoimmune condition that primarily affects women aged 15-44. It presents challenges with its varied and difficult-to-diagnose symptoms.
Managing lupus requires a comprehensive approach that considers the whole person. A systems-focused approach may offer support and encouragement to those living with lupus.
