The common clinical manifestations of thrombocytopenia are mainly skin and mucous membrane bleeding symptoms, such as purpura, gum bleeding, vomiting blood, black stools, hematuria, etc. In severe cases, internal bleeding may also occur.
The clinical manifestations of thrombocytopenia are related to the degree of thrombocytopenia.
1. Clinically, when the platelet count is greater than 50×10^9/L or the platelet count is (30~50)×10^9/L, it is often not accompanied by bleeding tendency, and the latter can be seen occasionally with a few skin petechiae and ecchymoses.
2. However, when the platelet count is less than 30×10^9/L, it can be accompanied by obvious bleeding tendency, such as epistaxis, gingival bleeding, blood blisters in the mouth, petechiae and ecchymosis of the skin and mucous membranes, etc. In severe cases, it can lead to internal bleeding (the most common is intracranial hemorrhage), which is directly threatening to the patient’s life.
It is crucial to clarify whether there is thrombocytopenia and the degree of its reduction in a timely manner clinically, and a definitive diagnosis under the guidance of a physician is required.
