Nosebleed (Epistaxis) - Symptoms, Causes, Treatment & Prevention

```html

Overview

A nosebleed, medically known as epistaxis, is bleeding from the nasal mucosa (the lining inside the nose). It is one of the most common reasons people visit primary‑care clinics or emergency departments. Approximately 5–10 % of the general population will experience at least one episode of epistaxis each year, and 60 % of those cases occur in children under 10 years of age, while 30 % occur in adults over 40 years old.<sup>1</sup>

Most nosebleeds are anterior (originating from the front part of the nose) and are self‑limited. Posterior bleeds, which arise deeper in the nasal cavity, are less common but can be life‑threatening and require urgent medical attention.

Symptoms

• Bleeding from one or both nostrils – often described as a steady drip or gush.
• Blood on the face, upper lip, or in the mouth – especially with posterior bleeds.
• Feeling of blood “running down the throat” – may cause coughing or gagging.
• Post‑nasal drip of blood clots – small clots may appear in the back of the throat.
• Nasalance or “full” sensation – pressure or fullness in the nose.
• Associated symptoms – headache, facial pain, or sinus pressure if the underlying cause is sinusitis or trauma.
• Signs of anemia (rare with isolated epistaxis) – fatigue, pallor, shortness of breath if bleeding is prolonged.

Causes and Risk Factors

Epistaxis can be divided into idiopathic (no clear cause) and secondary bleeds caused by an underlying condition or trigger. Common causes include:

• Local trauma – nose picking, facial injury, nasal suction during intubation, or vigorous blowing.
• Dry air – low humidity dries the delicate mucosal vessels, making them more prone to rupture (common in winter heating season).
• Inflammation/infection – rhinitis, sinusitis, or viral upper‑respiratory infections.
• Allergic rhinitis – frequent rubbing/scratching of the nasal lining.
• Medications – anticoagulants (warfarin, direct oral anticoagulants), antiplatelet agents (aspirin, clopidogrel), intranasal corticosteroids, and nasal decongestant sprays (rebound vasoconstriction).
• Systemic disorders – hypertension, hereditary hemorrhagic telangiectasia (HHT), von Willebrand disease, platelet dysfunction, liver cirrhosis, or renal failure.
• Substance use – cocaine or methamphetamine inhalation causes vasoconstriction and mucosal ulceration.
• Neoplasms – benign (nasal polyps) or malignant tumors can erode vessels.
• Structural abnormalities – deviated septum or nasal septal perforation.

Risk factors that increase the likelihood of a nosebleed include:

• Age < 5 years (fragile nasal vessels) or > 60 years (arterial wall changes).
• Chronic rhinosinusitis or allergic rhinitis.
• Use of blood‑thinning medication or herbal supplements (e.g., ginkgo, garlic).
• High blood pressure (uncontrolled hypertension is associated with more severe bleeds).
• Living in arid climates or using indoor heating without humidification.

Diagnosis

The goal of evaluation is to identify the source of bleeding, determine whether it is anterior or posterior, and uncover any underlying systemic disorder.

History

• Onset, duration, frequency, and amount of blood loss.
• Recent trauma, nasal surgeries, or intubation.
• Medication list (including OTC and supplements).
• Associated symptoms (headache, facial pain, fever, bruising).
• Past medical history of hypertension, bleeding disorders, liver disease, or cancers.

Physical Examination

• Inspect both nostrils with a headlamp and nasal speculum.
• Identify visible bleeding points – most anterior bleeds arise from Kisselbach’s plexus (Little’s area) on the anterior septum.
• Assess blood pressure and heart rate.
• Examine oral cavity and oropharynx for posterior blood.
• Look for signs of systemic disease (petechiae, bruises, telangiectasias).

Laboratory & Imaging (when indicated)

• Complete blood count (CBC) – to assess hemoglobin/hematocrit.
• Coagulation profile (PT/INR, aPTT) – especially if on anticoagulants or with a bleeding history.
• Platelet function tests or von Willebrand factor assays if a coagulopathy is suspected.
• Blood pressure monitoring – repeated measurements for hypertension.
• Imaging: CT of the paranasal sinuses if a tumor or sinus disease is suspected; angiography for refractory posterior bleeds.

Treatment Options

Management follows a stepwise approach: simple first‑aid measures, medical therapy, and, if necessary, procedural interventions.

Initial First‑Aid (Self‑Care)

1. Stay calm and sit upright – leaning forward prevents swallowing blood.
2. Pinch the soft part of the nose (just below the bony bridge) for 5–10 minutes.
3. Apply a cold compress to the nasal bridge to cause vasoconstriction.
4. If bleeding persists, repeat pinching or proceed to medical treatment.

Medical Management

• Topical vasoconstrictors – oxymetazoline or phenylephrine spray (use only once, avoid >48 h).
• Topical cautery – silver nitrate applied to identified bleeding points after the area is anesthetized.
• Systemic control of risk factors – adjust anticoagulant dosage, treat hypertension, manage underlying infection.

Procedural Interventions

• Anterior nasal packing – gauze or commercial absorbable sponges (e.g., Merocel); usually left 24–48 h.
• Posterior packing – balloon catheters (e.g., Foley balloon) for posterior bleeds; requires hospital monitoring.
• Endoscopic arterial ligation – cauterizing or suturing the sphenopalatine artery branch for recurrent posterior epistaxis.
• Embolization – interventional radiology can occlude feeding vessels when surgery fails.

Medications for Underlying Causes

• Antifibrinolytics (tranexamic acid) – topical spray or oral dose for refractory bleeds.
• Desmopressin (DDAVP) – in patients with mild von Willebrand disease or platelet dysfunction.
• Antihypertensives – ACE inhibitors, ARBs, calcium‑channel blockers as per blood‑pressure goals.

Living with Nosebleed (Epistaxis)

While occasional nosebleeds are common, frequent episodes can affect quality of life. Practical strategies include:

• Humidify indoor air – use a humidifier set to 40‑50 % relative humidity.
• Saline nasal irrigation – isotonic saline sprays or neti pots keep mucosa moist (avoid tap water if immunocompromised).
• Avoid nasal trauma – keep fingernails trimmed, discourage nose picking, and use soft tissue when blowing.
• Gentle nasal decongestant use – limit topical oxymetazoline to ≤3 days to prevent rebound vasodilation.
• Medication review – discuss with your clinician any blood‑thinners or supplements that may increase bleeding risk.
• Regular blood‑pressure checks – aim for <130/80 mmHg for most adults (American Heart Association guideline).
• Carry a bleeding‑control kit – includes a small tube of petroleum jelly, saline spray, and a pressure‑bag device.

Prevention

Many nosebleeds can be prevented with simple lifestyle modifications and medical measures:

• Maintain indoor humidity; use a room humidifier during dry seasons.
• Apply a thin layer of petroleum jelly or a water‑based nasal moisturizer to the anterior septum once daily.
• Limit alcohol intake and avoid smoking, both of which irritate the nasal mucosa.
• Control blood pressure through diet (DASH eating plan), regular exercise, and medication adherence.
• When using anticoagulants, keep INR or drug-specific levels within therapeutic range; ask your provider about dose adjustments if nosebleeds become frequent.
• Wear protective equipment (helmets, face masks) during activities with a high risk of facial injury.

Complications

If epistaxis is not promptly managed, several complications may arise:

• Significant blood loss – can lead to anemia, especially in children or the elderly.
• Secondary infection – nasal packing can become a nidus for bacterial growth; signs include foul odor, fever, or purulent discharge.
• Hypoxia – large posterior bleeds may impair oxygen exchange if airways become obstructed.
• Cardiac stress – rapid volume loss can precipitate tachycardia or exacerbate heart failure.
• Recurrent bleeding – untreated underlying disorders (e.g., HHT) may cause frequent, difficult‑to‑control epistaxis.
