When thrombocytopenia occurs, the first thing you need to do is to find out the cause and treat the cause in order to improve the platelets. Thrombocytopenia is mainly caused by decreased production and excessive destruction. 1. Reduced production, such as bone marrow hematopoietic function abnormalities caused by insufficient production of diseases, such as aplastic anemia, acute leukemia, myelodysplastic syndromes, tumor bone marrow invasion, etc., need to be targeted at the primary cause of the disease for treatment. Insufficient hematopoietic raw materials due to insufficient platelet production, such as megaloblastic anemia, need to supplement folic acid, vitamin B12. 2. Increased platelet destruction, such as idiopathic thrombocytopenic purpura, and thrombocytopenia secondary to autoimmune diseases, for autoantibodies destroy platelets, resulting in thrombocytopenia, the first line of treatment can be given to glucocorticoids immunosuppressive therapy, such as the effect is not good, can be considered human immunoglobulin, thrombopoietin, rituximab, or even cut the spleen and other treatments. Patients with cirrhosis and hypersplenism may also have thrombocytopenia due to increased platelet destruction as a result of splenic hyperfunction, which can be treated by targeting splenic hyperfunction. For patients with thrombocytopenia, it is recommended to consult the hematology department of regular hospitals for reasonable treatment.
