Introduction
In general, bloody nasal discharge may be caused by various factors such as dry climate, intense physical activity, acute rhinitis, allergic rhinitis, or sinusitis. In dry environments, the nasal mucosa can easily become dry and develop small cracks, leading to blood-tinged mucus. To prevent this, maintain indoor air humidity by using a humidifier, drink plenty of water to stay hydrated, and keep the body sufficiently moisturized.
In general, bloody nasal discharge may be caused by various factors such as dry climate, intense physical exercise, acute rhinitis, allergic rhinitis, and sinusitis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. Specific analysis is as follows:
1. Dry Climate
In dry environments, the nasal mucosa can easily become dry and develop small cracks, leading to blood-tinged nasal discharge. Maintain indoor air humidity using a humidifier, drink plenty of water, and stay well-hydrated.
2. Intense Physical Exercise
During vigorous exercise, elevated blood pressure causes nasal blood vessels to expand, which may lead to vessel rupture and bleeding due to excessive pressure. Perform proper warm-up exercises before physical activity and avoid sudden, intense exertion.
3. Acute Rhinitis
Acute rhinitis is caused by viral or bacterial infection of the nasal mucosa, resulting in congestion and swelling of the mucous membrane. This may cause small blood vessels in the nasal cavity to rupture, leading to blood-tinged nasal discharge. Symptoms may include nasal congestion and sneezing. Medications such as loratadine tablets, roxithromycin tablets, or cefixime granules may be taken as prescribed by a doctor.
4. Allergic Rhinitis
Allergic rhinitis may be triggered by exposure to allergens. In affected individuals, the nasal mucosa overreacts to these allergens, causing mucosal swelling and congestion, which may result in bloody nasal discharge. Common accompanying symptoms include clear runny nose and nasal itching. It is recommended to use medications such as cetirizine hydrochloride tablets, ebastine tablets, or mizolastine modified-release tablets under the guidance of a healthcare professional.
5. Sinusitis
Sinusitis is often caused by upper respiratory infections or nasal conditions. Increased purulent secretions in the sinuses irritate the nasal mucosa, causing congestion and swelling, which may lead to blood-tinged nasal discharge. Additional symptoms may include headache and facial pain. Medications such as amoxicillin dispersible tablets, cefuroxime axetil dispersible tablets, or Qianbai rhinitis tablets may be used under medical supervision to relieve symptoms.
In addition, maintain good personal hygiene, follow a light diet, and ensure adequate rest.
