Condition analysis:
Thrombotic thrombocytopenic purpura is a rare disorder of the blood-coagulation system, causing extensive microscopic thromboses to form in small blood vessels throughout the body. It is not thought to be hereditary.

Instructions:
Prevention: Since the cause of ITP is unknown, there are no specific ways of preventing it. However, there are steps that can be taken to help prevent bleeding and injuries that are more serious for people with ITP.
-- Take precautions such as padding an infant's crib or play area.
-- Make sure that older children wear helmets and protective gear when playing sports to help reduce bruising injuries.
-- When platelet counts are low, contact sports such as football and even rougher game playing may have to be stopped temporarily.
-- People who have ITP should also avoid medications that contain aspirin or ibuprofen; these medicines can reduce platelet function.
