Whether or not nosebleeds in the elderly can be cured depends on the cause of the nosebleed. If it is caused by environmental factors, nasal hemangioma or deviated nasal septum, it can be cured; if it is caused by nasopharyngeal cancer, it cannot be cured. 1. Environmental factors: if the nosebleed is caused by dry air, bad nose picking habit, etc., which leads to the erosion of nasal mucous membrane, it can be cured by increasing the humidity of nasal cavity, changing the bad nose picking habit, etc., which can reduce the probability of erosion of mucous membrane, and then cure the nosebleed caused by this condition. 2. Nasal hemangioma or deviated nasal septum: if there is hemangioma or deviated nasal septum in the nasal cavity of the elderly, the patients often have recurrent nosebleeds, which can be cured by surgery to remove or correct. Patients with hemangioma can also undergo electrocoagulation, laser and other ways to carbonize the wound to prevent recurrence, and then achieve the cure of nosebleed caused by this condition. 3. Nasopharyngeal cancer: when the elderly have malignant tumors in nasopharyngeal minister, when they inhale backward forcefully on their nose or secretion, there may be blood in snot in the light case, and nosebleed in the heavy case. In order to treat the disease, radiotherapy, chemotherapy or surgery is needed, but because the disease is a malignant tumor, there is a certain degree of metastasis and recurrence. If you have nosebleeds in the elderly, it is recommended that you consult a doctor in time for examination and standardized treatment under the guidance of a doctor.
