Nosebleeds every other day are clinically referred to as recurrent nosebleeds, and a distinction needs to be made between children, young people and the elderly. In children, nosebleeds are mostly caused by allergic rhinitis, which can lead to nasal itching, resulting in repeated nose picking and nose rubbing, and allergy causes increased vascular fragility, leading to the occurrence of nosebleeds. Recurrent rhinorrhea in young people is mostly due to mucosal erosion at the front of the nasal septum, accompanied by nasal septal deviation, and the bleeding surface is mostly located on the convex side of the nasal septum, resulting in increased mucosal tension, and mucosal erosion and bleeding due to stimulation by external dust and air. Recurrent nasal bleeding in the elderly is mostly related to hypertension, and is mostly accompanied by arteriosclerosis, poor vascular elasticity, and blood vessels are prone to rupture when blood pressure increases, and bleeding points are mostly located at the back end of the nasal cavity.
