Immune thrombocytopenia (ITP) is a rare autoimmune condition in which the body’s immune system destroys healthy platelets, a component of the blood involved in clotting. Symptoms can include easy or excessive bruising, petechiae (tiny red dots on the skin caused by broken or leaky blood vessels), bleeding from the gums or nose, blood in urine or stools, unusually heavy menstrual flow, and fatigue. Treatment depends on the severity of bleeding and the platelet count. In mild cases, treatment may not be needed.
