Overview of Thrombocytopenia
Causes of Thrombocytopenia
Many disorders can cause thrombocytopenia, but these disorders fall into three main categories: Too few platelets are produced Too many platelets are destroyed Too many platelets trapped in the spleen Thrombocytopenia can occur when the bone marrow does not produce enough platelets, as happens in Overview of Leukemia or other bone marrow disorders. Infection with Overview of Hepatitis , the Platelets can become entrapped in an enlarged spleen, as happens in Cirrhosis of the Liver , Massive red blood cell transfusions can dilute the concentration of platelets in the blood. Finally, the body may use or destroy too many platelets, as occurs in many disorders, three of the most notable being Immune Thrombocytopenia (ITP) , Some drugs such asheparin, certain antibiotics, ethanol, anticancer drugs, andquininecan also cause thrombocytopenia. Drug-induced cytopenia may be the result of Decreased platelet production by the bone marrow (caused by bone marrow toxicity) Increased platelet destruction (immune-mediated thrombocytopenia)
