Reduced platelets are not necessarily leukemia, the platelet index in normal blood is (100~300) x 10^9/L, while low platelets means that the platelet count in the blood is less than 100 x 10^9/L. There are many reasons for reduced platelets, and it is not necessarily leukemia. Common factors include aplastic anemia, acute leukemia, and drug factors.
1. Aplastic anemia: it may be due to genetic factors, viral infections, and chemical drug factors that cause bone marrow hematopoietic dysfunction, leading to platelet reduction. The main manifestations are anemia, fever due to infection, bleeding (e.g. skin bleeding, nosebleed) and so on.
2. Acute leukemia: the cause of the disease is still unclear, it may be due to biological factors, physical factors or genetic factors, etc. caused by immature hematopoietic cells proliferating in the bone marrow, resulting in inhibition of normal bone marrow hematopoietic function, which leads to platelet reduction. It is common in fever, dizziness, fatigue, pallor and other symptoms.
3. Drug factors: some drugs can also cause platelet reduction, such as antitumor drug methotrexate, etc.; anti-epileptic drug phenytoin sodium, etc.; will inhibit the hematopoietic function of the bone marrow, resulting in platelet reduction.
In addition, there are many other causes of platelet reduction, such as hypersplenism, idiopathic thrombocytopenic purpura, etc. It is recommended to go to the hospital in a timely manner, to clarify the cause of the disease, and then follow the doctor’s instructions for treatment.
