Nosebleeds (Epistaxis): Causes, Treatment, and When to See an ENT Specialist

Nosebleeds, also called epistaxis, are very common and can happen at any age. While most nosebleeds are mild and easily treated at home, frequent or severe bleeding may indicate nasal dryness, irritation, allergies, sinus inflammation, or underlying medical conditions.

Understanding why nosebleeds occur and how to treat them can help prevent recurrence and reduce anxiety when bleeding happens.

What Causes Nosebleeds?

The inside of the nose contains many small blood vessels located close to the surface. These vessels can break easily due to irritation, dryness, or trauma.

Common causes of nosebleeds include:

Dry air and nasal dryness

Low humidity, indoor heating, and air conditioning can dry the nasal lining, increasing the risk of bleeding.

Nose picking or irritation

Minor trauma to the delicate lining of the nose is one of the most common causes of nosebleeds in both children and adults.

Allergies and sinus inflammation

Inflammation from allergic rhinitis, sinus infections, and chronic congestion can irritate nasal tissues and increase bleeding risk.

Upper respiratory infections

Colds and viral infections can cause nasal irritation and frequent nose blowing, leading to bleeding.

Overuse of nasal sprays

Excessive use of decongestant sprays such as Afrin® (oxymetazoline) may dry and irritate nasal tissues.

Medications that thin the blood

Aspirin, anticoagulants, and certain supplements may increase bleeding risk.

Structural causes

A deviated septum, septal perforation, or prominent blood vessels may predispose some patients to recurrent nosebleeds.

Types of Nosebleeds

Most nosebleeds are classified based on where bleeding originates.

Anterior nosebleeds

These occur near the front of the nasal septum and are the most common type. They are usually mild and manageable at home.

Posterior nosebleeds

These occur deeper in the nose and may cause heavier bleeding. Posterior nosebleeds are more common in older adults and may require medical treatment.

How to Stop a Nosebleed

If a nosebleed occurs, the following steps are recommended:

1. Sit upright and lean slightly forward

2. Gently blow the nose to remove clots

3. Spray oxymetazoline (Afrin®) into the bleeding nostril if available

4. Pinch the soft part of the nose closed firmly

5. Hold pressure continuously for 10 minutes (use a timer)

6. Repeat once if needed

Avoid tilting the head backward, as this may cause blood to drain into the throat.

How to Prevent Nosebleeds

Preventive care focuses on keeping the nasal lining healthy and well moisturized.

Helpful prevention strategies include:

• Use saline nasal spray regularly

• Apply nasal saline gel or ointment inside the nostrils

• Use a humidifier at night

• Avoid nose picking or aggressive nose blowing

• Manage allergies and sinus inflammation

• Limit overuse of decongestant sprays

• Stay well hydrated

Maintaining moisture in the nasal lining can significantly reduce recurrence.

When to See an ENT Specialist for Nosebleeds

Evaluation by an ENT specialist may be recommended if nosebleeds are:

• Frequent or recurrent

• Difficult to stop

• Heavy or prolonged

• Associated with nasal obstruction

• Occurring after nasal trauma

• Associated with anemia symptoms

• Causing significant anxiety or disruption

An ENT evaluation may include nasal endoscopy to identify the source of bleeding and determine the best treatment approach.

Treatment Options for Recurrent Nosebleeds

Treatment depends on the cause and severity of bleeding.

Options may include:

• Nasal moisturizing regimens

• Treatment of allergies or sinusitis

• Adjustment of medications

• Cauterization of bleeding vessels

• Management of structural nasal issues

Most nosebleeds can be successfully managed with conservative treatment.
