Introduction
Epistaxis is a term used in traditional Chinese medicine referring to a condition characterized primarily by nasal bleeding. It may be caused by improper diet, trauma, sinusitis, nasal polyps, hypertension, or other factors. Because the underlying causes vary, treatment methods should be selected according to the specific circumstances. In summary, due to different etiologies leading to these symptoms, management approaches may differ. Patients are advised to seek timely medical evaluation at a正规 hospital.

Nosebleed is a term used in traditional Chinese medicine referring to a condition characterized primarily by nasal bleeding. It may be caused by improper diet, trauma, sinusitis, nasal polyps, hypertension, or other factors. Due to the different underlying causes, treatment methods should be selected according to specific circumstances. The detailed analysis is as follows:

1. Improper Diet

If one frequently consumes greasy foods recently, it may lead to excessive internal heat (fire) in the body, which can easily result in blood-heat and nosebleeds. In such cases, drinking more water can help reduce internal heat.

2. Trauma

The nasal mucosa is very delicate; any external impact or collision may rupture the capillaries inside the nasal cavity, leading to nosebleeds. Patients can apply cold compresses to alleviate symptoms.

3. Sinusitis

Sinusitis has a high incidence rate and is classified into acute and chronic types. Acute sinusitis is usually caused by upper respiratory tract infections due to bacteria or pathogens. Chronic sinusitis often develops from untreated acute cases, with a longer disease course and recurring symptoms. Under inflammatory stimulation, the aforementioned nosebleeds may occur. Treatment may include medications such as budesonide inhalation aerosol or azelastine fluticasone nasal spray, under medical guidance.

4. Nasal Polyps

Nasal polyps commonly affect adults and are frequently found in the maxillary sinus and middle nasal turbinate. Besides nosebleeds, patients may also experience difficulty breathing and runny nose. For this condition, patients should seek timely treatment at a reputable hospital, typically involving surgical removal.

5. Hypertension

Nosebleeds caused by hypertension usually occur in the morning or after excessive physical activity, often involving heavy bleeding. Many patients become anxious upon seeing significant blood loss, which further elevates blood pressure and exacerbates the situation. Patients may take medications such as nifedipine sustained-release tablets or compound captopril tablets as prescribed by a doctor to relieve symptoms.

In summary, because the causes of the above symptoms vary, appropriate management approaches differ accordingly. It is recommended that patients promptly visit a qualified medical institution for accurate diagnosis and targeted treatment based on the identified cause.

What does epistaxis mean?
In general, epistaxis refers to nosebleeds, which are characterized by bleeding from the nasal cavity due to rupture or injury of blood vessels within the nose. The nasal cavity contains abundant and relatively fragile blood vessels. These vessels are prone to rupture and cause nosebleeds when affected by factors such as irritation, dryness, excessive cleaning, or nasal trauma.

What causes nosebleeds?
In general, nosebleeds are medically referred to as epistaxis. Nosebleeds may be associated with factors such as dry climate, intense physical exercise, rhinitis, hypertension, hemophilia, and others. It is recommended to seek medical attention promptly and receive treatments—such as general management and medication—under the guidance of a physician. In daily life, maintain moisture in the nasal passages and avoid applying cold compresses immediately after vigorous exercise.

How can one cause a nosebleed?
Excessive anger, frequent late-night activity, or consuming overly greasy foods can easily lead to “internal heat” (a traditional Chinese medicine concept), which may trigger epistaxis (nosebleeds). The nasal mucosa is particularly fragile when capillaries are already compromised. Even minor trauma—such as a bump or blow to the nose—can rupture nasal capillaries and cause epistaxis. Additionally, abnormally dry air increases vascular fragility, making bleeding more likely.

What should I do if my nosebleed is caused by broken capillaries?
Nosebleeds caused by ruptured capillaries can initially be managed by packing the nasal cavity with a clean cotton ball, which may help control or alleviate bleeding to some extent. Patients with active or recurrent epistaxis require a thorough evaluation at a hospital. Nasal endoscopy can identify and precisely locate the bleeding site, enabling targeted hemostatic procedures such as electrocautery or radiofrequency ablation.

Can sinusitis cause nosebleeds?
Sinusitis can cause epistaxis (nosebleeds), but such nosebleeds are typically uncommon and not severe. They are usually associated with mechanical irritation—such as nose-picking, rubbing the nose, or forceful nose-blowing. Inflammation of the nasal cavity and sinuses renders the mucosa fragile, more prone to bleeding and injury. Additionally, rhinitis and sinusitis can cause nasal pruritus (itching).

What Causes Nosebleeds?
Nosebleeds may be caused by “excessive internal heat” (a traditional Chinese medicine concept). When patients experience excessive internal heat, nosebleeds can occur. Consuming spicy or stimulating foods without dietary caution easily triggers internal heat, leading to nosebleeds. Similarly, avoiding plain boiled water and neglecting adequate hydration can also readily cause internal heat and subsequent nosebleeds. Additionally, during the dry autumn and winter seasons, excessively dry air—especially without timely humidification—can also result in epistaxis (nosebleeds).

What should I do if I frequently experience nosebleeds due to rhinitis?
Patients with rhinitis who frequently experience epistaxis may use isotonic seawater to irrigate the nasal cavity; locally, erythromycin or tetracycline ophthalmic ointment—or other oily preparations—may be applied to the nasal mucosa. Anti-inflammatory medications may be prescribed based on the severity of rhinitis and whether a bacterial infection is present. During the intermediate stage of chronic rhinitis, patients with dry atrophic rhinitis are particularly prone to epistaxis, often accompanied by symptoms such as nasal dryness, epistaxis, and crusting.

Can allergic rhinitis in children cause nosebleeds?
Nosebleeds are not actually a common symptom of allergic rhinitis; however, some children with allergic rhinitis do experience epistaxis. This is because the nasal mucosa in children is soft and highly vascularized. In allergic rhinitis, allergen exposure causes the nasal mucosa to become increasingly congested and edematous, thereby impairing its defensive capacity.
