Autoimmune refers to a condition in which an individual's immune system mistakenly attacks their own body, causing damage and inflammation. This can occur when the immune system fails to recognize its own cells or tissues and instead perceives them as foreign invaders that need to be eliminated. Autoimmune disorders can affect various parts of the body, including the skin, joints, blood vessels, kidneys, and other organs. Some common autoimmune conditions include rheumatoid arthritis, lupus, multiple sclerosis, type 1 diabetes, and celiac disease. Treatment typically involves managing symptoms and may involve medications to suppress the immune system or address specific inflammation-related issues.
