The causes of thrombocytopenia in children include excessive destruction, decreased production and abnormal distribution.
1. Excessive destruction: mostly due to viral infections such as respiratory tract infections, gastrointestinal tract infections, etc., the body’s immune response occurs after the infection and leads to the production of antiplatelet antibodies, which leads to an increase in the destruction of platelets and a decrease in the number of platelets.
2. Reduced platelet production: commonly seen in hematologic diseases such as leukemia, aplastic anemia, immune thrombocytopenia, etc., usually manifested as bone marrow suppression, resulting in reduced platelet production.
3. Abnormal distribution: mainly due to various causes of splenomegaly or hypersplenism, platelets will be retained in the spleen, resulting in a significant reduction in the number of platelets in the blood, and splenectomy is generally recommended.
Children with thrombocytopenia are advised to consult a doctor in time to find the cause of the disease and actively treat it under the doctor’s guidance to avoid delaying the condition.
