Frequent bleeding from the nose is a clinical manifestation of a variety of diseases, and you can’t tell which disease is the harbinger of a nosebleed. Frequent bleeding from the nose may be caused by dry rhinitis, deviated nasal septum, primary thrombocytopenia and other diseases. 1. Dry rhinitis: patients with this disease have dry nasal mucosa, reduced glandular secretion, and crusting on the surface of the nasal turbinate, which makes it easy for the nose to bleed frequently and the phenomenon of blood in the snot. 2. Deviated nasal septum: in the convex surface of the deviated septum and the bone spine, the mucous membrane is tense and thin, and it is easy for the mucous membrane to erode and bleed when stimulated by airflow and dust. 3. Primary thrombocytopenia: thrombocytopenia will lead to reduced coagulation function, which will easily cause nasal capillary rupture and nosebleed. If the symptom of frequent nosebleeds persists without relief, you should actively seek medical examination to clarify the diagnosis and standardize the treatment, so as not to delay the condition.
