Bleeding Nose (Epistaxis)

What is Bleeding Nose (Epistaxis)?

Epistaxis, more commonly called a nosebleed, is the loss of blood from the lining of the nasal passages. It can range from a few drops that stop on their own to profuse bleeding that fills the nostrils and drips down the throat. While most nosebleeds are harmless and resolve quickly, they can sometimes signal an underlying medical condition that needs attention.

About 60% of people will experience at least one nosebleed in their lifetime, and children are especially prone because the blood vessels inside the nose are delicate. Adults over age 50, however, are more likely to have bleeding related to medication use or systemic disease.

Common Causes

Most nosebleeds are “anterior” – they originate from the front part of the nasal septum where tiny blood vessels (the Kiesselbach plexus) are close to the surface. The following conditions and factors are the most frequently reported triggers:

• Dry indoor air – Low humidity dries the nasal mucosa, making it fragile.
• Trauma – Nose picking, forceful blowing, or facial injuries.
• Allergic rhinitis – Chronic rubbing and inflammation increase vessel rupture.
• Upper‑respiratory infections – Colds and sinusitis cause congestion and frequent blowing.
• Anticoagulant or antiplatelet medications – Warfarin, direct oral anticoagulants, aspirin, clopidogrel, and even high‑dose ibuprofen can prolong bleeding.
• Systemic hypertension – Elevated blood pressure can stress nasal vessels.
• Blood‑clotting disorders – Hemophilia, von Willebrand disease, or liver disease impair clot formation.
• Structural abnormalities – Deviated septum, nasal polyps, or tumors (benign or malignant) can disrupt normal blood flow.
• Substance use – Cocaine, methamphetamine, or chronic alcohol use irritates the nasal lining.
• Environmental irritants – Cigarette smoke, chemical fumes, and pollutants.

Associated Symptoms

When a nosebleed occurs, patients often notice other signs that help pinpoint the cause:

• Nasally congested or runny nose
• Itching, sneezing, or watery eyes (allergy‑related)
• Facial pain or pressure (sinus infection)
• Bruising easily elsewhere on the body (possible clotting disorder)
• Headache or dizziness (especially if blood loss is significant)
• Blood‑tinged sputum or vomiting blood (posterior bleed that drains down the throat)
• Fever, chills, or malaise (infection)
• History of recent trauma, surgery, or dental work

When to See a Doctor

Most nosebleeds stop on their own within 10‑15 minutes of applying pressure. However, you should contact a health‑care professional if you experience any of the following:

• Bleeding lasts longer than 20 minutes despite firm pressure.
• Bleeding recurs more than once a week.
• More than one full twist‑off nasal packing is required to control the bleed.
• Blood loss is heavy enough to cause weakness, fainting, or a drop in blood pressure.
• You are taking blood‑thinning medication and cannot stop it.
• Accompanying symptoms such as severe facial pain, swelling, high fever, or signs of infection.
• History of clotting disorder, liver disease, or recent major surgery.
• Unexplained weight loss, night sweats, or persistent nasal congestion (to rule out tumors).

Diagnosis

During a medical evaluation, a clinician will usually follow these steps:

1. History taking

• Onset, duration, frequency, and location (anterior vs. posterior).
• Recent trauma, medication list (including over‑the‑counter NSAIDs), and underlying medical problems.
• Associated symptoms (headache, fever, bruising, etc.).

2. Physical examination

• Inspection of both nostrils with a bright light and nasal speculum.
• Identification of the bleeding source – most anterior bleeds are seen at Kiesselbach’s plexus.
• Assessment for septal deviation, polyps, or visible lesions.

3. Ancillary tests (when indicated)

• Complete blood count (CBC) – to detect anemia or platelet abnormalities.
• Coagulation profile (PT/INR, aPTT) – especially if the patient uses anticoagulants.
• Blood pressure measurement – hypertension can be a contributing factor.
• Imaging (CT or MRI of sinuses) – if a posterior bleed, tumor, or sinus disease is suspected.

Treatment Options

Treatment depends on the severity, location, and underlying cause of the bleed.

First‑aid measures (home care)

1. Stay calm and sit upright. Lean slightly forward—this prevents blood from flowing down the throat and causing gagging.
2. Pinch the soft part of the nose (just below the bony bridge) for 10‑15 minutes while breathing through the mouth.
3. Apply a cold compress or an ice pack wrapped in a cloth to the nasal bridge; vasoconstriction helps stop bleeding.
4. After the bleed stops, avoid blowing the nose, bending over, or vigorous activity for at least 24 hours.
5. Moisturize the nasal mucosa with saline sprays, petroleum‑jelly, or a thin layer of cotton applicator dipped in saline.

Medical interventions (performed by health‑care providers)

• Cauterization – Application of silver nitrate or electrocautery to the identified vessel.
• Nasal packing – Inserting gauze or specialized nasal tampons (e.g., Merocel) to apply pressure.
• Posterior packing or balloon catheters – Required for posterior bleeds, which are less common but more serious.
• Topical vasoconstrictors – Oxymetazoline or phenylephrine spray may be used (short‑term only).
• Correction of underlying disorders – Adjusting anticoagulant dosage, treating hypertension, supplementing vitamin K for warfarin excess, or managing clotting factor deficiencies.
• Surgical ligation or arterial embolization – Rare, reserved for refractory or life‑threatening bleeds.

When medication adjustments are needed

If you are on blood thinners, never stop them on your own. Speak with your prescriber; they may temporarily reduce the dose, switch to a shorter‑acting agent, or order laboratory monitoring.

Prevention Tips

Most nosebleeds can be avoided with simple lifestyle changes and environmental modifications.

• Humidify indoor air – Use a humidifier, especially during winter or in dry climates.
• Keep nasal passages moist – Apply saline spray or a thin layer of petroleum jelly twice daily.
• Avoid nasal trauma – Discourage nose picking, and trim fingernails short.
• Gentle nose blowing – Blow one nostril at a time, using soft tissue.
• Manage allergies – Use antihistamines, intranasal steroids, or allergen avoidance strategies to reduce inflammation.
• Control blood pressure – Follow a heart‑healthy diet, stay active, limit sodium, and take prescribed antihypertensives.
• Review medication list – Discuss with your doctor whether any over‑the‑counter NSAIDs or supplements increase bleeding risk.
• Stay hydrated – Adequate fluid intake keeps mucous membranes supple.
• Quit smoking and limit alcohol – Both irritate nasal tissue and impair clotting.

Emergency Warning Signs

Key Take‑aways

Bleeding nose (epistaxis) is usually benign, but persistent or heavy bleeding warrants prompt medical evaluation. Simple home measures—pinching the soft part of the nose, applying a cold compress, and keeping the nasal passages moist—resolve most cases. Maintaining a humid environment, managing allergies, controlling blood pressure, and reviewing medication use are effective preventive strategies. When in doubt, especially if warning signs or recurrent episodes appear, seek professional care to rule out serious underlying conditions.
