Autoimmune Disease

📖What is Autoimmune Disease?

Autoimmune disease occurs when the immune system, which normally protects the body by attacking foreign invaders such as bacteria and viruses, mistakenly identifies the body's own healthy tissue as a threat and launches a sustained attack against it. This misdirected immune response can target a single organ, as seen in type 1 diabetes affecting the pancreas, or multiple organ systems simultaneously, as seen in systemic lupus erythematosus. There are more than eighty recognized autoimmune diseases, and they tend to be chronic conditions marked by periods of flares and remission rather than a single acute illness. Diagnosis often relies on a combination of clinical features and specialized blood tests that detect autoantibodies, the abnormal antibodies produced against the body's own tissue.
