Anonymous users2024-02-11Thrombocytopenia should first be identified to clarify the severity of the disease, not careless, and should not rely on dietary therapy alone. To find out** there are some tests that need to be done, here are four common causes of thrombocytopenia:1
Ineffective platelet production It is common in some patients with megaloblastic anemia who are deficient in vitamin B12 or folate, and is characterized by thrombocytopenia, bleeding tendency, pancytopenia, normal or even increased megakaryocytes in the bone marrow, and therefore ineffective platelet production. With megaloblastic poverty, platelets can return to normal. 2.
Thrombopoietin Deficiency This disorder is thrombocytopenia due to congenital thrombopoietin deficiency. The disease is mostly hereditary, with hemorrhagic manifestations beginning in infancy, decreased platelet count, normal number of megakaryocytes, and no special changes in morphology and structure. 3.
Cyclic Thrombocytopenia It is a bleeding disorder caused by cyclic thrombocytopenia of unknown cause. The disease is common, with thrombocytopenia alternating with thrombocytosis or normal at regular intervals, usually 20 to 30 days apart. It is more common in women and often coincides with menstruation, with thrombocytopenia and increased bleeding during menstruation.
Megakaryocytes generally do not decrease, and are mainly characterized by **mucosal hemorrhage, with no special effect**. 4.Thrombocytopenia caused by splenic disease Under normal circumstances, 1 3 platelets in the body are stagnant in the spleen, and when there is an enlarged spleen, such as portal hypertension, Gaucher's disease, lymphoma, sarcoidosis, folty syndrome, etc., the platelet count can be reduced, but the total amount of platelets in the body is not reduced.
After epinephrine injection, platelet count can be markedly elevated for a certain period of time. Sometimes, there may be a concomitant factor of increased platelet destruction. It is recommended to actively go to the hospital for diagnosis and treatment.
