Frequent nosebleeds 2-3 times a day may be due to atrophic rhinitis, deviated nasal septum, aplastic anemia and other causes. 1. Atrophic rhinitis: its occurrence may be related to endocrine disorders, autonomic dysfunction, vitamin deficiency, genetic factors and other reasons. Due to the stimulation of inflammation, patients may have symptoms such as nasal congestion, nasal dryness and nosebleed, i.e. the phenomenon of frequent nosebleed 2-3 times a day. 2. Deviated nasal septum: It refers to the deviation or localized protrusion of nasal septum morphologically to one side or both sides, which is mainly caused by uneven development of nasal cavity, trauma, occupying lesions and other reasons. Due to the irritation of the protruding part, patients may have frequent nosebleeds 2-3 times a day. 3. Aplastic anemia: It is a bone marrow hematopoietic failure disorder that may be caused by different etiologies and mechanisms, mainly due to viral infection, chemical factors, radiation and other reasons. Due to the abnormal hematopoietic function, patients may suffer from bleeding, infection and other symptoms. Therefore, patients with aplastic anemia may also have frequent nosebleeds 2-3 times a day. Frequent nosebleeds can also be caused by tumors, etc. It is recommended to go to the hospital in time for a systematic examination to make a clear diagnosis.
