Platelets have the function of coagulation, and the hazards of lowering them include bleeding and inducing systemic symptoms.
1. Bleeding: mainly including mucosal bleeding, surgical hemorrhage, subcutaneous bleeding, intracranial hemorrhage and so on.
(1) Mucosal bleeding: the barrier of mucous membrane is relatively fragile, such as gastrointestinal mucous membrane, urinary tract mucous membrane, oral mucous membrane, conjunctiva, etc. After thrombocytopenia, it is easy to induce bleeding of mucous membrane.
(2) Surgical hemorrhage: during surgery, if platelets cannot stop bleeding in time, it will lead to hemorrhagic anemia in the light case, or hemorrhage and death in the heavy case.
(3) Subcutaneous hemorrhage: platelet lowering subcutaneous hemorrhage, purpura, petechiae, etc. of the skin.
(4) Intracranial hemorrhage: severe thrombocytopenia may lead to intracranial hemorrhage, which is life-threatening.
(2) Induced systemic symptoms: patients may have skin itching, chills, fever, nausea, vomiting, abdominal pain and so on.
If the patient’s symptoms of thrombocytopenia are serious, or if the symptoms persist and do not get better, he/she should go to the hospital for treatment in time to avoid delaying his/her condition.
