Patients with cerebral infarction usually do not have direct gum bleeding. Most of the gum bleeding is caused by gingivitis or poor vascular fragility due to blood system diseases or vitamin C deficiency, which can be examined by the stomatology department. In addition, patients with cerebral infarction usually need to take long-term oral medications to improve circulation and activate blood circulation, as well as anti-platelet drugs such as aspirin or clopidogrel, which can lead to abnormal platelet function or abnormal coagulation function after long-term oral intake, causing gum bleeding. If the results are normal and the amount of bleeding is small, local pressure can be applied to stop the bleeding and oral vitamin C can be taken to increase the elasticity of blood vessels. If platelet function and coagulation function are abnormal, it is recommended to discontinue anti-platelet drugs and coagulation medications.
