Autoimmune Diseases
Autoimmune diseases occur when the body’s immune system mistakenly attacks its own healthy cells, tissues, or organs. Instead of protecting against harmful invaders like bacteria and viruses, the immune system targets the body itself, causing inflammation and tissue damage. Common examples include rheumatoid arthritis, lupus, and type 1 diabetes. These conditions can affect nearly any part of the body and often require ongoing management to control symptoms and prevent complications.

How are autoimmune diseases diagnosed?
Diagnosis relies on clinical symptoms and medical history, plus tests for autoantibodies, inflammatory markers, imaging, and sometimes tissue biopsy.
Can autoimmune diseases be cured or only managed?
