Nosebleeds: Causes, Prevention, and When to See a Doctor

Nosebleeds (epistaxis) are common and rarely serious, but deliberately inducing one is unsafe and not recommended. Understanding triggers can help prevent them.

Common Causes

• Dry Air: Low humidity dries nasal membranes, causing cracking and bleeding.
• Nasal Trauma: Picking, blowing too hard, or injury.
• Allergies or Infections: Inflammation from colds, sinusitis, or allergic rhinitis.
• Medications: Blood thinners, nasal sprays (especially steroid sprays if misused).
• Structural Issues: Deviated septum, nasal polyps.
• Underlying Conditions: Hypertension, bleeding disorders (less common).

Prevention Tips

• Use a humidifier in dry climates or heated indoor air.
• Apply saline nasal gel or petroleum jelly inside nostrils gently.
• Avoid nose picking; keep children's nails trimmed.
• Blow nose gently.
• Manage allergies with appropriate treatment.

When to Seek Medical Care

• Bleeding lasts longer than 20 minutes despite direct pressure.
• Bleeding is heavy or rapid.
• Follows a head injury or facial trauma.
• Accompanied by dizziness, fainting, or difficulty breathing.
• Recurrent nosebleeds (more than once a week).
• Child under 2 years old.
• On blood thinners or have a bleeding disorder.

To stop a nosebleed: sit upright, lean slightly forward, pinch the soft part of the nose for 10–15 minutes without checking. If it persists, seek help.
