Nasal Bleeding (Epistaxis)

What is Nasal Bleeding (Epistyria)?

Nasal bleeding, medically known as epistaxis, is the loss of blood from the tissues inside the nose. It is one of the most common reasons people visit urgent‑care clinics or call their primary‑care doctor. Most episodes are minor, stop on their own, and are not a sign of serious disease. However, recurrent or heavy bleeds can point to an underlying condition that needs evaluation.

Epistaxis can originate from two main areas:

• Anterior (front) nosebleeds – arise from the thin, delicate vessels of the Kiesselbach’s plexus (the “Little’s area”) on the nasal septum. These are the overwhelming majority (≈90 %) of cases.
• Posterior (back) nosebleeds – involve larger branches of the sphenopalatine artery deeper in the nasal cavity. They are less common but more likely to be severe and require medical attention.

Common Causes

Many factors can irritate or damage the nasal mucosa, leading to bleeding. The following are the most frequently encountered causes:

• Dry air – low humidity (common in winter heating or desert climates) dries the nasal lining, making vessels fragile.
• Trauma – nose picking, facial injuries, or aggressive nasal suction (e.g., from nasal sprays) can rupture capillaries.
• Upper‑respiratory infections – colds, sinusitis, and allergies cause inflammation and frequent nose blowing.
• Medications – anticoagulants (warfarin, DOACs), antiplatelet agents (aspirin, clopidogrel), and nasal corticosteroid sprays can increase bleeding risk.
• Hypertension – high blood pressure may exacerbate bleeding, especially posterior bleeds.
• Structural abnormalities – deviated septum, nasal polyps, or enlarged turbinates can create turbulent airflow that irritates vessels.
• Systemic diseases – bleeding disorders (von Willebrand disease, hemophilia), liver disease, or thrombocytopenia.
• Environmental irritants – smoke, chemicals, or strong odors can inflame the nasal mucosa.
• Hormonal changes – pregnancy and estrogen therapy increase nasal vascularity.
• Tumors – rare but possible; benign (e.g., juvenile nasopharyngeal angiofibroma) or malignant tumors can bleed.

Associated Symptoms

Bleeding is often accompanied by other signs that help identify the underlying cause:

• Running or stuffy nose (rhinorrhea)
• Sneezing or itching (allergic rhinitis)
• Facial pain or pressure (sinusitis)
• Headache or facial fullness (nasal polyps)
• Bruising elsewhere, petechiae, or easy bruising (coagulopathy)
• Fever or malaise (infection)
• Palpitations or shortness of breath (possible anemia from chronic bleeding)
• Nasal crusting or scabs (chronic dryness)

When to See a Doctor

Most nosebleeds are self‑limiting, but you should schedule a medical visit if any of the following occur:

• Bleeding lasts longer than 20 minutes despite applying pressure.
• Bleeding recurs more than twice within a month.
• More than a half‑cup (≈120 mL) of blood is lost.
• You are taking blood‑thinning medication and cannot control the bleed.
• You have symptoms of anemia (fatigue, dizziness, rapid heartbeat).
• You notice frequent nosebleeds on both sides (bilateral) or associated with facial pain, swelling, or visual changes.
• Bleeding follows a head injury, especially if you have a concussion history.

Diagnosis

Evaluation usually begins with a focused history and physical examination.

History

• Onset, duration, frequency, and severity of bleeds.
• Recent trauma, medication list (especially anticoagulants, NSAIDs, nasal sprays).
• Associated symptoms (fever, sinus pain, bruising, etc.).
• Medical conditions that affect clotting (liver disease, inherited bleeding disorders).
• Environmental exposures – dry climate, smoking, occupational dust.

Physical Examination

• Vital signs – especially blood pressure and heart rate.
• Anterior nasal examination with a nasal speculum and good lighting to locate the bleeding source.
• Posterior examination (using a headlamp or rhinoscope) if anterior source is not identified or if bleeding is profuse.
• Inspection of oral cavity, throat, and ears for blood tracking.
• Skin exam for petechiae, bruises, or signs of systemic disease.

Laboratory & Imaging Tests

• Complete blood count (CBC) – to assess hemoglobin, hematocrit, and platelet count.
• Coagulation profile (PT/INR, aPTT) – especially if on anticoagulants or with a bleeding history.
• Basic metabolic panel – evaluates renal function if certain medications are used.
• Imaging (CT scan of sinuses) – reserved for suspected posterior bleeds, facial trauma, or tumor suspicion.

Treatment Options

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

First‑Aid Home Measures (for mild anterior bleeds)

1. Stay calm. Anxiety can raise blood pressure.
2. Lean forward slightly (do not tilt back) to avoid swallowing blood.
3. Pinch the soft part of the nostrils together firmly for 10‑15 minutes.
4. Apply a cold compress or ice pack to the bridge of the nose to cause vasoconstriction.
5. After bleeding stops, avoid blowing the nose, bending over, or strenuous activity for 24 hours.
6. Use a humidifier or saline nasal spray to keep the mucosa moist.

Medical Interventions

• Cauterization – chemical (silver nitrate) or electrical cautery applied to a visible bleeding point.
• Nasal packing – insertion of gauze, nasal tampon, or inflatable balloon devices to apply pressure; usually for persistent anterior bleeds.
• Posterior packing or arterial ligation – required for severe posterior bleeds; may involve endoscopic surgery or arterial embolization by interventional radiology.
• Medication adjustment – reviewing and possibly stopping anticoagulants or NSAIDs under physician guidance.
• Topical therapies – tranexamic acid spray or ointments (e.g., petroleum jelly) to promote clot formation.
• Management of underlying disease – controlling hypertension, treating coagulopathies, or addressing nasal tumors.

Post‑Bleed Care

• Continue nasal moisturizing with saline sprays or water‑based gels.
• Avoid nasal picking, aggressive blowing, or exposure to irritants.
• Follow up with your clinician if packing is used; they will schedule removal (usually within 24‑48 hours).
• Monitor hemoglobin if large volume loss is suspected.

Prevention Tips

Most nosebleeds can be avoided with simple lifestyle adjustments and environmental control.

• Humidify indoor air – aim for 40‑60 % relative humidity, especially in winter.
• Apply a thin layer of petroleum‑based ointment or a water‑based nasal gel to the inside of each nostril once or twice daily.
• Gentle nasal hygiene – use saline sprays instead of harsh decongestant sprays; limit use to ≤3 days.
• Stay hydrated – adequate fluid intake keeps mucosal tissues moist.
• Protect the nose from trauma – wear protective gear during sports or work involving impact.
• Manage allergies with antihistamines or intranasal steroids as prescribed.
• Control blood pressure with diet, exercise, and medication adherence.
• If you take anticoagulants, have regular INR/DOAC level checks and discuss any bleeding episodes with your prescribing physician.
• Avoid smoking and exposure to second‑hand smoke.

Emergency Warning Signs

Key Take‑aways

Nasal bleeding is usually benign, but persistent or heavy episodes warrant evaluation. Understanding common triggers, applying proper first‑aid techniques, and making preventive lifestyle changes can dramatically reduce the frequency of epistaxis. When in doubt, especially if warning signs appear, prompt medical assessment ensures safety and helps uncover any serious underlying condition.
