Bleeding Nose (Epistaxis) - Causes, Treatment & When to See a Doctor

What is Bleeding Nose (Epistaxis)?

Epistaxis, commonly known as a nosebleed, is the loss of blood from the nasal passages. It can range from a few drips to a profuse stream that lasts several minutes. Most nosebleeds originate from the delicate blood vessels that line the front (anterior) part of the nasal septum, but bleeding can also arise deeper in the back (posterior) of the nose. While occasional epistaxis is usually harmless, recurrent or severe bleeding may signal an underlying medical problem that needs attention.

According to the Mayo Clinic, up to 60 % of the population experiences at least one nosebleed in their lifetime, making it one of the most common ENT (ear‑nose‑throat) complaints seen in primary‑care settings.

Common Causes

Most nosebleeds fall into two broad categories: local factors that affect the nasal lining directly, and systemic conditions that impair blood clotting or alter blood vessel integrity. Below are the ten most frequent causes.

• Dry Air / Low Humidity – Winter heating or air‑conditioned environments dry out the nasal mucosa, making vessels fragile.
• Nasal Trauma – Picking the nose, sneezing forcefully, facial blows, or insertion of foreign objects.
• Upper Respiratory Infections – Colds, sinusitis, and allergies cause inflammation and frequent nose blowing.
• Medications – Anticoagulants (warfarin, apixaban), antiplatelet agents (aspirin, clopidogrel), and intranasal steroids can prolong bleeding.
• Hypertension – Elevated blood pressure can increase the pressure on fragile nasal vessels, especially in posterior bleeds.
• Bleeding Disorders – Congenital (e.g., hemophilia, von Willebrand disease) or acquired (e.g., liver disease, vitamin K deficiency).
• Structural Abnormalities – Deviated septum, nasal polyps, or a deviated turbinate can cause turbulent airflow and vessel irritation.
• Environmental Irritants – Smoke, chemical fumes, and potent odors irritate the nasal lining.
• Neoplasms – Benign (e.g., angiofibroma) or malignant tumors of the nasal cavity or sinuses can erode vessels.
• Systemic Diseases – Granulomatosis with polyangiitis, hereditary hemorrhagic telangiectasia (Osler‑Weber‑Rendu), and advanced renal disease can manifest with epistaxis.

Associated Symptoms

When a nosebleed occurs, patients often notice other signs that help clinicians identify the underlying cause.

• Sneezing or coughing that triggers bleeding
• Frequent nasal crusting or dryness
• Facial pain or pressure (suggesting sinusitis)
• Post‑nasal drip, sore throat, or ear fullness
• Bruising or bleeding from other sites (possible clotting disorder)
• Headache or visual changes (rare, may indicate posterior bleed or intracranial pathology)
• Fever, chills, or malaise (infection or systemic disease)
• Worsening hypertension symptoms—headache, dizziness, palpitations

When to See a Doctor

Most anterior nosebleeds stop with simple first‑aid measures. However, medical evaluation is advised when any of the following occur:

• Bleeding lasts longer than 20 minutes despite direct pressure.
• More than one (or a large) gauze pad or tissue is soaked.
• Bleeding recurs several times in a week.
• Bleeding is heavy (bright red, spurting) or comes from both nostrils.
• There is a history of clotting disorders, recent surgery, or use of blood‑thinners.
• Accompanying symptoms such as severe facial pain, vision changes, persistent headache, or signs of anemia (fatigue, pale skin, shortness of breath).
• You are pregnant, have uncontrolled hypertension, or have a known nasal tumor.

Diagnosis

Evaluation begins with a focused history and physical exam, followed by targeted testing if needed.

History

• Onset, duration, frequency, and location (anterior vs. posterior).
• Recent trauma, recent illnesses, medication list (especially anticoagulants, NSAIDs, nasal sprays).
• Medical conditions (hypertension, liver disease, bleeding disorders).
• Family history of hereditary bleeding disorders.

Physical Examination

• Vital signs, especially blood pressure and heart rate.
• Anterior nasal inspection with a speculum and good lighting.
• If the source is not visible, posterior nasal packing or endoscopic examination may be required.
• Examination of oral cavity, throat, and ear for concurrent bleeding.
• Assessment for signs of anemia (pallor, tachycardia).

Laboratory & Imaging Studies

• Complete blood count (CBC) – checks hemoglobin and platelet count.
• Coagulation profile (PT/INR, aPTT) – evaluates clotting cascade.
• Serum electrolytes, liver function tests if liver disease is suspected.
• Blood pressure monitoring for hypertensive contributors.
• Imaging (CT or MRI of sinuses) when a tumor, sinus disease, or facial fracture is suspected.
• Referral to an ENT specialist for persistent or posterior bleeds.

Treatment Options

Treatment is tailored to the severity, location of bleeding, and underlying cause.

First‑Aid / Home Management (for mild anterior bleeds)

1. Sit upright and lean forward – reduces blood flow to the nose and prevents swallowing blood.
2. Pinch the soft part of the nostrils for 10–15 minutes without releasing.
3. Apply a cold compress on the bridge of the nose to cause vasoconstriction.
4. After bleeding stops, use a saline nasal spray or a thin layer of petroleum jelly to keep the mucosa moist.
5. Avoid blowing the nose, picking, or heavy physical exertion for 24 hours.

Medical Interventions (performed by healthcare professionals)

• Topical vasoconstrictors (e.g., oxymetazoline, phenylephrine) applied with a cotton tip.
• Cauterization – chemical (silver nitrate) or electrical cautery of identified bleeding points.
• Nasal packing – gauze, absorbable sponges (e.g., Surgicel), or inflatable balloons for uncontrolled anterior or posterior bleeds.
• Tranexamic acid – oral or topical antifibrinolytic agent useful in patients with clotting issues.
• Systemic treatment of the underlying cause – adjust anticoagulant dosing, treat hypertension, manage sinus infection with antibiotics, or replace deficient clotting factors.
• Surgical options – endoscopic ligation of the sphenopalatine artery or arterial embolization for refractory posterior bleeds.

When Hospital Admission Is Needed

• Severe posterior epistaxis with ongoing blood loss.
• Hemodynamic instability (hypotension, tachycardia).
• Severe anemia (Hb < 8 g/dL) or need for blood transfusion.
• Failure of conservative measures after 30–60 minutes.

Prevention Tips

Many nosebleeds can be avoided with simple lifestyle modifications and routine care.

• Humidify indoor air during winter or in dry climates (humidifier set to 40‑50 %).
• Apply a thin layer of petroleum jelly or a saline nasal gel inside each nostril daily.
• Avoid nose picking and limit forceful nose blowing.
• Use saline nasal sprays regularly if you have allergies or frequent colds.
• Control blood pressure with diet, exercise, and medications as directed.
• Review any blood‑thinning medication with your prescriber; ask about dose adjustments if you experience frequent bleeds.
• Wear protective gear (helmets, face masks) during high‑impact sports.
• Stay well‑hydrated; adequate fluid intake keeps mucosal membranes moist.
• Quit smoking and limit exposure to second‑hand smoke.
• Schedule routine ENT check‑ups if you have a known nasal tumor, chronic sinus disease, or hereditary bleeding disorder.

Emergency Warning Signs

Call 911 or go to the nearest emergency department if you notice any of the following:

• Bleeding that does not stop after 20–30 minutes of continuous pressure.
• Large volume of blood (soaking >2 large gauze pads or a full cup of blood).
• Bleeding from both nostrils or the back of the throat (possible posterior bleed).
• Signs of shock: dizziness, fainting, rapid heartbeat, pale skin, or confusion.
• Severe facial pain, swelling, or vision changes.
• Sudden onset of nosebleed in a child after a head injury.
• Bleeding accompanied by high fever, stiff neck, or neurological symptoms (rare but can indicate serious infection or intracranial bleed).

Key Take‑aways

Epistaxis is usually benign, but it can signal an underlying health issue or become life‑threatening when it is severe or recurrent. Prompt first‑aid measures often halt mild bleeds, while persistent or heavy bleeding warrants professional evaluation. By recognizing risk factors, maintaining nasal moisture, and managing systemic conditions like hypertension or anticoagulation therapy, most nosebleeds can be prevented.
