Bleeding tongue is a symptom of lingual inflammation, tongue trauma or blood system diseases, etc. It is recommended to consult a doctor for symptomatic treatment. 1. Tongue inflammation: when poor oral hygiene leads to inflammation of the tongue, the tongue will be swollen or cracked, and then bleeding or pain will occur; oral hygiene must be maintained and anti-inflammatory drugs (such as cotrimoxazole gargle, amoxicillin, etc.) should be used under the guidance of the doctor in order to control the inflammation. 2. Tongue trauma: tongue bite or food scratch will cause tongue tissue laceration, and then bleeding and other symptoms of the tongue; we should seek medical treatment for compression to stop bleeding or surgical suture treatment. 3. Blood system diseases: such as leukemia will lead to abnormal coagulation function of the body, so that the skin and mucous membranes are very easy to bleed, so the oral mucosa such as the tongue mucosa is also easy to bleed; we must consult the hematology department for specialized treatment in order to effectively prevent the occurrence of tongue bleeding.
