Nosebleeds can be a symptom of local damage to the nose or a consequence of diseases in other organs and systems of the body. SM-Clinic otolaryngologist Asiyat Zirkueva told socialbites.ca in more detail about the causes of this phenomenon.
He stated that the nasal mucosa is supplied with abundant blood. The largest vascular density is located in the Kisselbach area in the lower anterior part of the nasal septum, and 90% of nosebleeds are associated with this area.
The doctor found that cold, dry air is one of the most common local causes of nosebleeds. In his opinion, dryness leads to drying out of the mucous membrane, increasing the fragility of the walls of blood vessels, especially when sneezing, rubbing and removing crusts from the nose.
“So-called local causes also include: bruises and injuries to the nose, including improper nose blowing; improper use of nasal sprays (directed towards the septum); rhinitis (allergic, medical, atrophic); bleeding after surgery; formations of the nasal cavity and sinuses (bleeding polyp, juvenile angiofibroma of the nasopharynx); deviated septum; foreign body in the nasal cavity; exposure to chemical irritants,” Zirkueva said.
He said systemic causes include: arterial hypertension; blood diseases and poor blood clotting (hemophilia, thrombocytopenia, leukemia); pregnancy; telangiectasia (Rendu-Osler disease); liver diseases (cirrhosis, hepatitis).
“Also common factors of nosebleeds include hypo- and vitamin deficiencies, such as: vitamin C deficiency, vitamin A (plays an important role in the nutrition of the epithelium of the nasal mucosa), vitamin K (participates in blood clotting). “It is very important to follow this vitamin, especially for those who are actively involved in sports,” he added.
The expert also concluded that nosebleeds can occur against the background of physical stress and overheating of the body (for example, due to sunstroke), as well as when taking anticoagulants and drugs containing aspirin.
