What causes persistent nosebleeds?

Under normal circumstances, the nose does not bleed abnormally. However, persistent or recurrent nosebleeds (epistaxis) warrant prompt medical evaluation to identify the underlying cause. So, what could be causing persistent nosebleeds?

What Causes Persistent Nosebleeds?

Persistent nosebleeds may stem from excessive liver fire (“excess heat in the Liver”) and overly vigorous blood circulation, according to Traditional Chinese Medicine (TCM) principles. Additionally, consuming nourishing foods—such as ginseng, turtle soup, or donkey-hide gelatin (ejiao)—may exacerbate internal “heat,” thereby increasing susceptibility to epistaxis. Environmental factors also play a role: prolonged exposure to dry air—whether at home or in the workplace—can dehydrate the nasal mucosa, rendering it increasingly dry and fragile. This compromises the integrity of capillaries within the nasal cavity, making them prone to rupture and subsequent bleeding.

Sinusitis may also contribute to nosebleeds—for instance, blood clots may be observed when picking the nose, indicating pre-existing nasal pathology. Nosebleeds resulting from such conditions require particular attention and timely medical treatment. Moreover, avoid habitual nose-picking: hands carry bacteria that can introduce external pathogens into the nasal cavity, worsening inflammation. Please exercise caution.

Nosebleeds are common in daily life, yet their causes are multifactorial. If nosebleeds occur frequently, it is essential to rule out underlying nasal disease. To help prevent recurrence, consider using a humidifier in bedrooms or living rooms to maintain optimal indoor humidity; consume vitamin C–rich foods—including fruits and vegetables; follow a light, balanced diet; and cultivate healthy lifestyle habits.
