autoimmune disease
C1Formal, Technical, Academic, Medical
Definition
Meaning
A condition in which the body's immune system mistakenly attacks its own healthy cells and tissues.
A broad category of chronic, often systemic disorders characterised by immune dysfunction where the body fails to distinguish self from non-self. These diseases can affect single organs or multiple systems, ranging from mild to life-threatening, and often involve periods of flare-ups and remission.
Linguistics
Semantic Notes
Typically used as a singular count noun (an autoimmune disease) or as a non-count mass noun (research into autoimmune disease). It functions as a hypernym for specific conditions like lupus, rheumatoid arthritis, or type 1 diabetes.

Mnemonic
Think of an **AUTO**matic alarm system that goes off and attacks your own house instead of a burglar. Your **IMMUNE** system is like that faulty 'auto-immune' system, attacking your 'self'.
Conceptual Metaphor

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'autimmune disease' (автоиммунная болезнь) which is understood but less idiomatic. The standard Russian equivalent is 'аутоиммунное заболевание'.
- Do not confuse with 'allergy' (аллергия) or 'immunodeficiency' (иммунодефицит).
Common Mistakes
- Incorrect plural: 'autoimmunes diseases' (correct: autoimmune diseases).
- Misspelling: 'auto-immune' (hyphenated form is less common in modern medical usage).
- Misuse: Using for diseases caused by external pathogens (e.g., calling COVID-19 an autoimmune disease).

FAQ
Frequently Asked Questions
No, autoimmune diseases are not contagious. They are disorders of the body's own immune system and cannot be spread from person to person.
Most autoimmune diseases currently have no definitive cure. Treatment focuses on managing symptoms, reducing immune system activity (immunosuppression), and inducing remission to prevent long-term damage.
Common examples include type 1 diabetes, rheumatoid arthritis, lupus, multiple sclerosis, inflammatory bowel disease (Crohn's disease, ulcerative colitis), and psoriasis.
Yes, many autoimmune diseases disproportionately affect women. For instance, conditions like lupus and rheumatoid arthritis are significantly more common in women than in men, though the reasons are complex and involve hormonal, genetic, and environmental factors.
