Question

A 20-year-old male comes to the casualty with complaints of bleeding from nose for the last one hour.
What are the causes and risk factors for epistaxis?

Hint:

For treating epistaxis, it is crucial to manage the underlying cause, whether it's controlling blood pressure, humidifying the air, or adjusting medications. Applying pressure and using decongestant nasal sprays can help stop bleeding in the short term.

Answer 1

Step 1: Understanding Epistaxis.
Epistaxis, commonly known as a nosebleed, occurs when blood vessels inside the nasal cavity rupture, leading to bleeding. It is a common condition and can range from mild to severe, depending on the underlying cause.

Step 2: Causes of Epistaxis.
The most common causes of epistaxis are:
- Trauma: Physical injury to the nose or the nasal cavity, such as from a blow to the face or frequent nose picking.
- Infections: Upper respiratory infections, sinusitis, or viral infections can inflame the mucosa of the nose, leading to bleeding.
- Underlying Systemic Conditions: Conditions like hypertension or blood clotting disorders (e.g., hemophilia, von Willebrand disease) can predispose individuals to nosebleeds.
- Nasal Tumors: Benign or malignant growths in the nasal cavity can cause frequent or persistent epistaxis.
- Use of Medications: Drugs that affect the blood's ability to clot, such as anticoagulants (warfarin, aspirin) or nasal sprays (which dry out the nasal lining), can cause bleeding.

Step 3: Risk Factors for Epistaxis.
Common risk factors include:
- Dry Air: Environments with low humidity, particularly in winter, can dry out the nasal mucosa, making it more prone to bleeding.
- Hypertension: High blood pressure can cause the blood vessels in the nose to rupture more easily.
- Medications: Anticoagulants (e.g., warfarin, heparin), nonsteroidal anti-inflammatory drugs (NSAIDs), and corticosteroid nasal sprays can increase the likelihood of epistaxis.
- Alcohol and Smoking: Both alcohol consumption and smoking can lead to irritation of the nasal mucosa and blood vessels, increasing the risk of bleeding.
- Age and Gender: Epistaxis is more common in children (due to frequent nose picking) and older adults (due to fragile blood vessels and systemic health issues).

Step 4: Conclusion.
Epistaxis can have many causes, ranging from minor trauma to more serious systemic conditions. Identifying the underlying cause and risk factors is essential for managing the condition and preventing recurrence.
