Bleeding gums after radiation therapy should be treated under a doctor’s supervision, and you need to keep your mouth clean and reduce the intake of irritating foods. Radiotherapy can cause some adverse reactions, including bleeding gums. If the gums bleed after radiotherapy, you should go to the hospital to complete the routine blood test to see whether the white blood cells, platelets and other indicators are normal. If the bleeding is caused by thrombocytopenia after radiotherapy, consider platelet-boosting treatment, such as oral aminopeptide tablets, injection of thrombopoietin or platelet input, if necessary. At the same time, patients need to keep the oral cavity clean to avoid complications of infection. Reduce the intake of stimulating foods to minimize oral discomfort. Once the gums bleed after radiotherapy, it is recommended to go to the regular hospital for examination and treatment as soon as possible to clarify the cause, and then consider the treatment plan as appropriate.
