Autoimmune Disorders

Autoimmune disorders are a large group of diseases in which the immune system mistakenly attacks the body's own cells. There are over 80 recognized autoimmune conditions; together they affect roughly 5–10% of the population.

Quick Facts

  • Number of types: >80 recognized
  • Affected: ~5–10% of people
  • More common in: Women

Overview

Normally, the immune system distinguishes self from non-self. In autoimmune disease, this regulation breaks down. The result can be inflammation and damage to one organ system (organ-specific) or many (systemic).

Common Autoimmune Conditions

Common Features

  • Fatigue (almost universal)
  • Joint pain or stiffness
  • Skin rashes
  • Recurrent fevers
  • Hair loss
  • Tingling or numbness
  • Flares and remissions

Diagnosis

  • Detailed history and physical exam
  • Autoantibody panels (ANA, RF, anti-CCP, specific antibodies)
  • Inflammatory markers (ESR, CRP)
  • Imaging and organ-specific testing
  • Biopsies when needed

Treatment

  • Anti-inflammatory medications (NSAIDs, steroids)
  • Disease-modifying antirheumatic drugs (DMARDs)
  • Biologic therapies (anti-TNF, anti-IL-17, anti-CD20, others)
  • Small-molecule targeted therapies (JAK inhibitors)
  • Treatment of specific organ involvement
  • Lifestyle: stress management, exercise, sleep, smoking cessation

When to See a Doctor

See a doctor for persistent unexplained fatigue, joint pain, rashes, or other symptoms that come and go. Rheumatologists, endocrinologists, gastroenterologists, and neurologists manage different autoimmune conditions depending on the organ affected.

Frequently Asked Questions

Are autoimmune diseases curable?

Most are chronic and not curable, but many can be controlled in long-term remission with modern treatments.

Can diet treat autoimmune disease?

Diet can support overall health and reduce some symptoms, but it does not replace medical treatment. Specific elimination diets are sometimes helpful (e.g., gluten-free for celiac disease).

Why are autoimmune diseases more common in women?

The reasons are not fully understood but include hormonal influences, X-chromosome effects on immune genes, and environmental factors.
