Epistaxis (Nosebleed)

What is Epistaxis (Nosebleed)?

Epistaxis, commonly known as a nosebleed, is bleeding from the nasal mucosa (the lining inside the nose). It can range from a few drops that stop on their own to profuse bleeding that requires medical attention. Most nosebleeds are anterior—originating from the front part of the nasal septum (the “Kiesselbach’s plexus”). Less frequently, bleeding may arise from deeper, posterior vessels, which tend to be more serious.

While a single episode is often harmless, recurrent or severe epistaxis can signal an underlying health problem, medication side‑effect, or structural issue that warrants evaluation.

Common Causes

Understanding the triggers helps both prevention and treatment. Below are the most frequent causes of epistaxis:

• Dry air & environmental irritation – Low humidity (e.g., winter heating) dries the nasal lining.
• Trauma – Nose picking, facial injury, or vigorous nose blowing.
• Upper‑respiratory infections – Colds, sinusitis, or allergic rhinitis cause inflammation and crusting.
• Medications – Anticoagulants (warfarin, DOACs), antiplatelet agents (aspirin, clopidogrel), and nasal sprays (corticosteroids, decongestants) can impair clotting.
• Systemic diseases – Hypertension, bleeding disorders (von Willebrand disease, hemophilia), liver disease, or platelet dysfunction.
• Structural abnormalities – Deviated septum, nasal polyps, or a perforated septum.
• Substance use – Cocaine, methamphetamine, or chronic alcohol use can damage nasal vessels.
• Neoplasms – Benign (e.g., hemangioma) or malignant tumors of the nasal cavity.
• Foreign bodies – Especially in children, objects lodged in the nose can cause bleeding.
• Hormonal changes – Pregnancy increases nasal blood flow, making nosebleeds more common.

Associated Symptoms

Other signs that often accompany a nosebleed can help pinpoint the cause:

• Nasal congestion or discharge (clear, purulent, or bloody)
• Facial pain or pressure
• Headache or facial swelling
• Fever or chills (suggesting infection)
• Easy bruising or prolonged bleeding from other sites (possible clotting disorder)
• Palpitations, shortness of breath, or dizziness (signs of significant blood loss or anemia)
• History of recent trauma or surgery
• Use of blood‑thinning medication or supplements (e.g., fish oil, vitamin E)

When to See a Doctor

Most nosebleeds resolve with simple home measures, but you should schedule a medical appointment if any of the following occur:

• Bleeding lasts longer than 20 minutes despite applying pressure.
• Bleeding recurs more than twice in a month.
• You have a known bleeding disorder or are on anticoagulant therapy.
• Severe pain, swelling, or deformity of the nose.
• Accompanying symptoms such as fever, persistent headache, or visual changes.
• Unexplained weight loss, night sweats, or a persistent foul odor from the nose (possible tumor).
• Signs of anemia: fatigue, pallor, rapid heartbeat.

Diagnosis

Evaluation begins with a focused history and physical exam. The goal is to identify the bleeding source, assess severity, and uncover any systemic contributors.

History

• Onset, duration, frequency, and amount of bleeding.
• Recent trauma, nasal surgeries, or foreign‑body insertion.
• Medication list (including over‑the‑counter and herbal supplements).
• Medical conditions: hypertension, liver disease, clotting disorders.
• Family history of bleeding disorders.

Physical Examination

• Inspection of the nasal cavity with a nasal speculum or otoscope to locate the bleeding site (anterior vs. posterior).
• Assessment of blood pressure and heart rate.
• Examination of the oral cavity, throat, and ears for blood.
• Skin exam for bruises or petechiae.

Laboratory & Imaging Tests (when indicated)

• Complete blood count (CBC) – evaluates anemia and platelet count.
• Prothrombin time (PT), activated partial thromboplastin time (aPTT) – assess clotting function.
• Serum electrolytes and renal function – especially if on anticoagulants.
• Imaging (CT or MRI) – reserved for suspected posterior bleeds, tumors, or sinus disease.

Treatment Options

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

Home (First‑Aid) Measures

1. Stay calm and sit upright. Lean forward slightly to avoid swallowing blood.
2. Pinch the soft part of the nose. Apply firm pressure for 10–15 minutes without releasing.
3. Apply a cold compress. A bag of ice wrapped in a cloth placed on the bridge of the nose can cause vasoconstriction.
4. Use a humidifier. Moist air helps keep the nasal mucosa hydrated.
5. Avoid nose blowing or picking. Wait at least 24 hours after the bleed stops.
6. If bleeding persists, try a topical vasoconstrictor (e.g., oxymetazoline spray) or a cotton ball soaked in petroleum jelly placed in the nostril.

Medical Interventions

• Cauterization – Chemical (silver nitrate) or electrical cautery of the identified bleeding vessel, usually for recurrent anterior bleeds.
• Anterior nasal packing – Gauze or specialized nasal tampons (e.g., Merocel) placed to apply pressure; typically removed after 24–48 hours.
• Posterior packing – Required for posterior bleeds; may involve balloon catheters or specialized gauze, often performed in an emergency department.
• Systemic therapy – If a coagulopathy is identified, vitamin K, fresh frozen plasma, or specific factor concentrates may be administered.
• Endoscopic surgery – For persistent or severe cases, especially when a structural lesion (e.g., tumor, vascular malformation) is present.

Medication Review & Adjustment

Discuss with your physician whether anticoagulants, antiplatelet agents, or nasal sprays can be temporarily paused, dose‑adjusted, or switched to an alternative.

Prevention Tips

Many nosebleeds can be avoided with simple lifestyle changes and environmental adjustments:

• Use a humidifier at home, especially in dry winter months.
• Apply a thin layer of saline nasal spray or petroleum jelly inside the nostrils 2–3 times daily.
• Avoid nose picking and excessive nose blowing.
• Wear protective gear (helmets, face masks) during sports or high‑risk activities.
• Control high blood pressure through diet, exercise, and medication adherence.
• Limit use of decongestant nasal sprays to no more than 3 consecutive days.
• Stay well‑hydrated and consider using a saline rinse (neti pot) to keep nasal passages moist.
• If you take blood thinners, have regular lab monitoring and discuss any bleeding episodes with your provider.
• Quit smoking and avoid exposure to second‑hand smoke, which irritates nasal mucosa.
• For children, keep small objects out of reach and supervise to prevent insertion into the nose.

Emergency Warning Signs

If you experience any of the following, seek emergency medical care (call 911 or go to the nearest emergency department) immediately:

• Bleeding that does not stop after 20–30 minutes of firm pressure.
• Heavy bleeding that soaks through gauze or a cloth within minutes.
• Signs of significant blood loss: dizziness, fainting, rapid heartbeat, or pale/clammy skin.
• Bleeding from both nostrils simultaneously (possible posterior bleed).
• Difficulty breathing or swallowing due to blood pooling in the throat.
• Severe facial pain, swelling, or deformity after trauma.
• Bleeding associated with a head injury, especially if you have a concussion or loss of consciousness.
