The causes of nosebleeds several times a day usually include deviated nasal septum, foreign objects in the nasal cavity and trauma to the nose, etc., which need to be treated in time once detected. 1. The mucous membrane of the septum in deviated nasal septum is relatively weak, and it is easy to induce nosebleeds when rubbing or blowing the nose inadvertently, especially for the elderly with poor blood vessel elasticity, which makes it easier to have nosebleeds. 2.. Foreign objects in the nasal cavity can irritate the nasal mucosa, and if the foreign objects stay for too long, they may cause nosebleeds. 3. Nasal cavity, sinus, and septum injury due to trauma is also prone to nosebleeds, and if the internal carotid artery or anterior sclerotic artery is injured, it can also lead to persistent nosebleeds. In serious cases, it is recommended to seek medical attention. Define the cause of the disease and carry out targeted treatment.
