Introduction
In general, sudden and persistent nosebleeds may be caused by factors such as dry environment, trauma, rhinitis, sinusitis, or deviated nasal septum. Patients should promptly visit a正规 hospital to determine the underlying cause and receive appropriate treatment. In daily life, it is important to maintain good living habits, follow a regular作息 schedule, and ensure sufficient sleep to help maintain normal physiological function.

Generally, sudden and persistent nosebleeds may be caused by factors such as dry environment, trauma, rhinitis, sinusitis, or deviated nasal septum. Patients should promptly visit a正规 hospital to determine the underlying cause and receive appropriate treatment. Specific analysis is as follows:

1. Dry Environment

When the air is excessively dry, especially during winter or in arid environments, the nasal mucosa can lose moisture, becoming dry and fragile. This may lead to rupture of capillaries within the nasal cavity, causing epistaxis (nosebleed). It is recommended to adjust indoor humidity appropriately—using humidifiers or saline sprays can help moisten the nasal mucosa.

2. Trauma

External impacts to the nose, nose picking, or forceful nose blowing may damage the nasal mucosa and trigger nosebleeds. In such cases, applying cold compresses can help stop the bleeding, with recovery typically occurring after a period of time.

3. Rhinitis

Rhinitis is usually caused by allergies, bacterial, or viral infections. These inflammatory conditions lead to nasal mucosal congestion, swelling, and blood vessel dilation, increasing the risk of bleeding. Under medical guidance, patients may use medications such as oseltamivir phosphate granules, Siji Kangbingdu oral liquid, or ribavirin tablets for treatment.

4. Sinusitis

Sinusitis refers to inflammation of the sinus mucosa, which can cause nasal mucosal congestion and swelling, thereby increasing the risk of bleeding. Additionally, sinusitis may also lead to symptoms such as nasal congestion, runny nose, and headaches. Patients may take medications such as Biyuan Tongqiao Granules, cefixime capsules, or Tongqiao Biyan Tablets as directed by a physician.

5. Deviated Nasal Septum

A deviated nasal septum may result from trauma, genetic factors, or chronic diseases. When the septum is displaced to one side, it may compress and irritate the mucosa on that side, increasing the likelihood of bleeding. Treatment options include septoplasty, septal resection, or other corrective surgical procedures, chosen under a doctor's guidance.

In daily life, it is important to maintain healthy habits, follow a regular sleep schedule, and ensure sufficient rest to support normal physiological function. Additionally, engaging in regular physical exercise helps enhance overall immunity.
