Dr. Muhammad Ghassanov, an ear, nose and throat specialist, stated that a deviated septum, high blood pressure, atrophic rhinitis, and tumors can all cause nosebleeds.
He says: "A deviated septum is a structural abnormality in the nose, where the septum deviates from the midline. This abnormality causes irregular airflow within the nasal passages, leading to constant irritation and dryness of the nasal mucosa. Constant dryness of the nasal mucosa increases the risk of microvascular injuries, which can trigger nosebleeds."
According to him, high blood pressure is another important cause of nosebleeds.
He says: "When blood pressure is high, blood vessels are subjected to increased pressure, especially the tiny capillaries in the nasal mucosa. Under high pressure, the walls of blood vessels are easily damaged, even by minor injuries."
The doctor points out that frequent episodes of high blood pressure increase the likelihood of nosebleeds, especially with age, because the walls of the blood vessels lose their elasticity.
According to the doctor, atrophic rhinitis may be another cause of nosebleeds, as it leads to increased dryness and fragility of the nasal mucous membrane, making it susceptible to mechanical damage.
He says: "One possible cause of nosebleeds is the presence of tumors in the nasal cavity. These tumors may be benign (polyps, hemangiomas, papillomas) or malignant. Nasal tumors are subject to trauma as a result of breathing, blowing the nose, or touching, which causes frequent bleeding."
According to him, one of the rare causes of nosebleeds is juvenile angiofibroma of the nasopharynx (a rare benign tumor, mainly affecting adolescent boys), characterized by mostly unilateral nosebleeds and requiring surgical treatment.
