An autoimmune condition is a medical disorder in which the immune system mistakenly attacks and destroys healthy body tissue. In such conditions, the body's defense mechanism fails to recognize its own cells and instead perceives them as foreign invaders that need to be eliminated. This can lead to inflammation, damage or destruction of various organs and systems in the body, causing a wide range of symptoms and complications. Autoimmune conditions are often chronic and may require lifelong management through medications, lifestyle changes, and other treatments. Some common examples include rheumatoid arthritis, type 1 diabetes, multiple sclerosis, and systemic lupus erythematosus.
