Introduction
In general, frequent nosebleeds occurring several times a day may be caused by habits such as nose picking, dry air, rhinitis, deviated nasal septum, thrombocytopenia, or other factors. Appropriate improvements can be made through general care, medication, surgical treatment, or other methods based on the specific situation. In daily life, maintain good hygiene habits and avoid touching the nasal cavity with hands; eat more fruits and vegetables rich in vitamins.
Generally, frequent nosebleeds occurring several times a day may be caused by habits such as nose picking, dry air, rhinitis, deviated nasal septum, thrombocytopenia, and other reasons. Depending on the specific situation, improvements can be made through general care, medication, or surgical treatment. A detailed analysis is as follows:
1. Nose-picking habit
Frequently picking the nose with fingers can cause fingernails to scratch and damage the nasal mucosa, disrupting the mucosal barrier and exposing blood vessels, making them prone to rupture and bleeding. Immediately stop the habit of nose picking. When the nasal cavity feels dry, use a cotton swab dipped in warm water to moisten it, and avoid forceful nose-blowing.
2. Dry air
Low environmental humidity causes rapid moisture loss from the nasal mucosa, leading to dryness, brittleness, and cracking. Small blood vessels become fragile and easily rupture, resulting in recurrent bleeding. Use a humidifier indoors to maintain humidity levels between 50% and 60%, and drink plenty of warm water daily to stay hydrated.
3. Rhinitis
Inflammation causes nasal mucosal congestion and swelling, increasing blood vessel fragility. Blood vessels may rupture easily during sneezing or nose-blowing. Under medical guidance, treatments such as mometasone furoate nasal spray, loratadine tablets, and physiological saline nasal spray can be used. Avoid exposure to allergens.
4. Deviated nasal septum
A nasal septum that is deviated toward one side results in thinning of the mucosa at the curved area. This region is constantly exposed to airflow, making it susceptible to injury and recurrent bleeding. Follow medical advice to take vitamin C supplements to promote mucosal healing. In severe cases, septoplasty may be required. After surgery, avoid applying pressure to the nose.
5. Thrombocytopenia
Reduced platelet count leads to impaired blood clotting function, causing repeated nosebleeds even from minor mucosal injuries, often accompanied by gum bleeding. Seek medical evaluation to determine the underlying cause. Take medications such as aplastic anemia peptide (amino-peptide) tablets, leucogen tablets, and caffeic acid tablets as prescribed. Avoid strenuous exercise to prevent injuries and collisions.
Maintain good daily hygiene habits and avoid touching the nasal cavity with hands. Eat a diet rich in fruits and vegetables containing vitamins, and avoid spicy and irritating foods. If nosebleeds are accompanied by dizziness, fatigue, or if bleeding cannot be stopped within 10 minutes, seek immediate medical attention.
