What are the main mechanisms of thrombocytopenia?

Thrombocytopenia can occur by four general mechanisms: (1) decreased production of platelets, (2) consumption of circulating platelets, (3) sequestration of platelets, and (4) increased destruction of circulating platelets or megakaryocytes.

Why does ITP cause thrombocytopenia?

What causes idiopathic thrombocytopenic purpura? In ITP, the immune system is stimulated to attack your body’s own platelets. Most often this is a result of antibody production against platelets. In a small number of cases, a type of white blood cell called T-cells will directly attack platelets.

How does thrombocytopenia develop?

    Heparin, a blood thinner, is the most common cause of drug-induced immune thrombocytopenia. If a medicine prevents your bone marrow from making enough platelets, the condition is called drug-induced nonimmune thrombocytopenia. Chemotherapy drugs and a seizure medicine called valproic acid may lead to this problem.
