What are the common causes of frequent nosebleeds?

Under normal circumstances, frequent nosebleeds may be caused by factors such as dryness inside the nasal cavity, nasal trauma, allergic rhinitis, atrophic rhinitis, or nasal polyps. Patients should promptly visit a reputable hospital to determine the underlying cause and receive targeted treatment. Specific analyses are as follows:

1. Dryness inside the nasal cavity

Dry climate, prolonged exposure to dry environments, or insufficient fluid intake can lead to dry nasal mucosa. When the nasal mucosa becomes dry, it is more prone to damage, exposing blood vessels to external stimuli and resulting in nosebleeds. In such cases, patients can drink more water or apply a cold, damp towel to the nose to help relieve symptoms.

2. Nasal trauma

Physical injuries such as collisions, falls, or excessive nose picking can damage the nasal tissues, directly injuring blood vessels or mucosal tissue within the nasal cavity and causing bleeding. It is recommended that patients use cold or warm compresses to promote vasoconstriction and alleviate bleeding.

3. Allergic rhinitis

Inflammation of the nasal mucosa triggered by allergic reactions to allergens such as pollen, dust mites, or animal dander can lead to nasal congestion, swelling, and dilated blood vessels, making them more susceptible to rupture and bleeding. Patients may take antihistamines such as loratadine tablets, cetirizine hydrochloride tablets, or ebastine tablets under medical guidance to improve symptoms.

4. Atrophic rhinitis

Chronic long-term inflammation in the nasal cavity can lead to mucosal atrophy and damage, causing the nasal lining to become thin and fragile, thus more vulnerable to external irritation and bleeding. Under a doctor’s supervision, patients may use medications such as mometasone furoate nasal spray, fluticasone propionate nasal spray, or oxymetazoline hydrochloride nasal spray for treatment.

5. Nasal polyps

Nasal polyps—abnormal growths of mucosal tissue in the nasal cavity—can exert local pressure, damage blood vessels, and increase the risk of bleeding. Additionally, the presence of polyps may obstruct normal mucus drainage, leading to increased dryness in the nasal cavity and worsening the tendency to bleed. In such cases, patients may seek treatment at a reputable hospital through procedures such as endoscopic sinus surgery, open sinus surgery, or refined endoscopic nasal-lacrimal surgery.

In daily life, it is recommended to maintain a positive mindset, avoid spicy, stimulating, and greasy foods, get adequate rest, and develop healthy lifestyle habits.
