Nose bleeding in the elderly may be caused by dry rhinitis, nasal capillary hemangioma, high blood pressure and other reasons. 1. Dry rhinitis: when the body function of the elderly decreases, the secretion function of the nasal mucosa decreases, which causes the dryness and erosion of the nasal mucosa, and the phenomenon of bleeding from the nose of the elderly may occur. 2. Nasal capillary hemangioma: the elasticity of the nasal mucosa of the elderly decreases, and the binding force of the submucosal tissue decreases, so it is easy for the nasal capillaries to expand and enlarge to form a nasal capillary hemangioma, and under the action of external stimulating factors, it leads to the rupture of capillary hemangioma, which causes the phenomenon of bleeding from the nose of the elderly. 3. Hypertension: with age, the incidence of hypertension increases, if the blood pressure is not well controlled may increase the risk of nasal vasodilatation and rupture, resulting in the occurrence of nose bleeding. Elderly nose bleeding, there may be atrophic rhinitis, nasal sinus malignant tumors, etc., it is recommended to go to the hospital in a timely manner, after the cause is clear, according to the doctor’s guidance for standardized treatment.
