Nosebleeds in the elderly can be caused by dry rhinitis, high blood pressure or nasal malignancy. Appropriate treatment can be taken according to different diseases, such as applying drugs, taking drugs or chemotherapy. 1. Dry rhinitis: due to older age, the mucous membrane of nasal cavity is not sufficiently secreted, and the nasal mucous membrane will be dry, resulting in frequent bleeding; medicines can be applied to the nasal mucous membrane, such as gentamycin, erythromycin ointment, etc., which can effectively alleviate the symptoms. 2. Hypertension: the elderly suffer from hypertension, which will lead to decreased elasticity of blood vessel wall, blood pressure fluctuation, nasal mucosa blood vessel rupture caused by bleeding; hypertensive patients can take amlodipine benzenesulfonate tablets, amlodipine, etc., to reduce blood vessel pressure through antihypertensive treatment to reduce the tendency to bleed. Nasal endoscopy can be used to find the bleeding point, local microwave or electrocoagulation to stop bleeding. 3. Nasal cavity malignant tumor: usually caused by unhealthy dietary habits, poor living environment, nasopharyngeal cancer and other nasal cavity malignant tumors, when it progresses to the late stage, there will be obvious symptoms of recurrent nosebleed; at this time, patients should treat the cavity tumor as early as possible, and chemotherapy and surgery can be used according to the situation in order to control the symptoms. There are other reasons for nosebleeds in the elderly, so we should find out the reasons and treat them in time, and should not use medicines blindly on our own.
