Idiopathic thrombocytopenic purpura (ITP) is a disorder that can lead to easy or excessive bruising and bleeding. The bleeding results from unusually low levels of platelets — the cells that help your blood clot.
Idiopathic thrombocytopenic purpura, which is also called immune thrombocytopenic purpura, affects both children and adults. Children often develop idiopathic thrombocytopenic purpura after a viral infection and usually recover fully without treatment. In adults, however, the disorder is often chronic.
Treatment of idiopathic thrombocytopenic purpura depends on your symptoms, your platelet count and your age. If you don't have signs of bleeding and your platelet count isn't too low, treatment for idiopathic thrombocytopenic purpura usually isn't necessary. More serious cases may be treated with medications or, in critical situations, with surgery.
