What causes heavy nosebleeds?

Generally, heavy nosebleeds may be caused by various factors, such as trauma, atrophic rhinitis, sinusitis, deviated nasal septum, hypertension, and others. Patients should go to the hospital for examination to determine the exact cause and cooperate with doctors for targeted treatment. The specific analysis is as follows:

1. Trauma

Nasal trauma is one of the most common causes of severe nosebleeds. Injuries from accidental falls, collisions, or fights can directly damage the nasal mucosa or blood vessels, leading to significant bleeding. Applying a cold compress to the nasal area can help reduce bleeding. Additionally, pressing the nostrils with fingers while leaning forward can also be effective.

2. Atrophic Rhinitis

Dry climate, excessive nasal cleaning, and insufficient fluid intake may lead to dryness of the nasal mucosa, making it fragile and prone to injury, which can result in rupture of small blood vessels and heavy bleeding. Using a humidifier to increase indoor humidity or applying moisturizing agents can help alleviate symptoms.

3. Sinusitis

Chronic or acute sinusitis can cause nasal mucosal congestion, swelling, and inflammation, increasing the risk of blood vessel rupture. Severe cases may lead to substantial nosebleeds, accompanied by symptoms such as nasal congestion and runny nose. Patients may take medications as prescribed by a doctor, such as Biyuan Tongqiao Granules, Cefixime Capsules, or Tongqiao Biyan Tablets, to help reduce inflammation.

4. Deviated Nasal Septum

This condition is often caused by genetic or developmental abnormalities and may present with symptoms like nasal obstruction and headaches. In severe cases, it can lead to mucosal erosion and heavy bleeding. It is recommended to visit a hospital for evaluation; once diagnosed, surgical treatments such as partial septal resection, three-line tension-reducing procedure, or septoplasty may be performed under medical guidance.

5. Hypertension

In patients with hypertension, increased pressure on blood vessel walls makes the nasal mucosal vessels more likely to rupture and bleed, especially during hypertensive episodes or sudden spikes in blood pressure, potentially causing severe bleeding. Patients may take antihypertensive medications as directed by a physician, such as Valsartan and Hydrochlorothiazide Tablets, Nifedipine Tablets, or Spironolactone Tablets.

In daily life, it is recommended to maintain a positive mindset, avoid spicy, stimulating, and greasy foods, get adequate rest, and develop healthy lifestyle habits.
