What are the causes of frequent nosebleeds?

Generally, frequent nosebleeds may be caused by factors such as nose picking, dry nasal passages, excessive internal heat ("shang huo"), rhinitis, or high blood pressure. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a healthcare professional. Specific analyses are as follows:

1. Nose picking: This may damage the nasal mucosa and lead to bleeding. When picking the nose, fingers or tools can scratch the delicate mucosal lining, creating small wounds that result in bleeding. To prevent such bleeding, it's advisable to break this habit and maintain good nasal hygiene—for example, gently rinsing the nasal cavity with clean water or saline solution.

2. Dry nasal passages: Dry environments or climates may deprive the nasal mucosa of sufficient moisture, making it fragile and prone to rupture, which can cause localized bleeding and possibly nasal itching. To relieve dryness, it's recommended to drink plenty of water, maintain appropriate indoor humidity, and use nasal sprays or apply moisturizing ointments to keep the nasal passages hydrated.

3. Excessive internal heat ("shang huo"): This condition may be related to consuming overly spicy foods or staying up late. When "heat" accumulates in the body, it may disturb the blood, causing it to flow abnormally and leading to nosebleeds. Patients are advised to take medications such as Niuhuang Qingfei Tablets, Yangyin Qingfei Pills, or Longdan Xiegan Decoction as directed by a physician.

4. Rhinitis: This is usually triggered by colds or exposure to allergens. The condition often causes nasal mucosal congestion and swelling. Localized inflammation can weaken the mucosa, making it more susceptible to rupture and bleeding. Patients should follow a doctor’s advice and may use medications such as Naiyuan Tongqiao Granules, Qianbai Rhinitis Tablets, or Amoxicillin Capsules to alleviate symptoms.

5. High blood pressure: This is commonly associated with unhealthy dietary habits and lack of physical activity. Elevated blood pressure increases stress on the blood vessels in the nasal cavity, weakening vessel walls and making them more likely to rupture and bleed. Dizziness may also occur. Patients should strictly follow medical advice and may take medications such as Amlodipine Atorvastatin Calcium Tablets, Enalapril Hydrochlorothiazide Dispersible Tablets, or Labetalol Hydrochloride Tablets to manage their condition.

In daily life, it is recommended to eat a light diet, drink plenty of warm water, and engage in moderate physical activities such as walking or jogging, all of which can support recovery and overall health.
