The normal range of platelet is (100~300)×10^9/L, when the platelet is 51×10^9/L, it suggests the existence of thrombocytopenia, the common causes are infection, cirrhosis, primary thrombocytopenia, various other hematologic diseases.
1. Infection: including viral, bacterial, fungal and other pathogenic microorganisms infection, often cause platelet destruction caused by increased platelet reduction, active anti-infective treatment platelets can be gradually recovered.
2. Cirrhosis: patients with cirrhosis can lead to hypersplenism, resulting in increased platelet destruction, platelet drop, often accompanied by anemia and leukocyte drop, with symptoms such as food loss, fatigue, anorexia, ascites, gastrointestinal bleeding.
3. Primary immune thrombocytopenia: excessive destruction of platelets and inhibition of platelet production due to immune factors, resulting in thrombocytopenia, glucocorticoids are preferred for treatment.
4. Other hematologic diseases: such as megaloblastic anemia, aplastic anemia, acute leukemia, myelodysplastic syndrome, etc. can cause thrombocytopenia.
Thrombocytopenia 51×10^9/L alone can not identify the disease, and should be combined with other tests, but when thrombocytopenia occurs, it is necessary to consult the hospital in time to identify the cause of the disease, and then treat the cause of the disease.
