Thrombocytopenia groups

Thrombocytopenia

Thrombocytopenia is any disorder in which there are not enough platelets. Platelets are cells in the blood that help blood to clot. This condition is sometimes associated with abnormal bleeding.

Thrombocytopenia is often divided into three major causes of low platelets:

• Low production of platelets in the bone marrow
• Increased breakdown of platelets in the bloodstream (called intravascular)
• Increased breakdown of platelets in the spleen or liver (called extravascular)
