Platelets higher than 1000 means that the number of platelets in peripheral blood is more than 1000×10⁹/L, the normal platelet count of peripheral blood is (100~300)×10⁹/L, and a platelet count ≥450×10⁹/L is called thrombocytosis, and platelets higher than 1000 × 10⁹/L is significantly more than normal, which can cause the following harm:
1. Thrombotic diseases: platelets are easy to adhere, aggregation, platelet increase is easy to form thrombotic diseases, easy to occur cardiovascular and cerebrovascular diseases such as coronary heart disease, cerebral embolism, cerebral infarction, as well as deep vein thrombosis, pulmonary embolism, and other diseases, easy to life-threatening.
2. hemorrhagic disease: commonly seen in the oral cavity, gums and other skin and mucous membrane bleeding, but also can cause intracranial hemorrhage, at this time easy to life-threatening.
3. Liver and spleen enlargement: when the course of the disease is long, liver and spleen enlargement will occur, which will cause discomfort.
Thrombocytosis is divided into primary thrombocytosis and secondary thrombocytosis. Primary thrombocytosis is a clonal disease of hematopoietic stem cells dominated by megakaryocyte hyperplasia, which is a bone marrow proliferative disease; secondary thrombocytosis refers to the stimulation of thrombocytosis by causes other than bone marrow, which is commonly seen in infections, acute blood loss, malignant tumors, anaemia and after splenectomy.
When platelets are found to be higher than 1000×10⁹/L, it is important to seek immediate medical attention to clarify the cause of the disease and treat it accordingly in a timely manner.
