Bleeding from the Nose (Epistaxis)

What is Bleeding from nose?

Bleeding from the nose, medically known as epistaxis, is the loss of blood from the nasal cavity. Most nosebleeds are small, start spontaneously, and stop on their own, but some can be profuse, recurrent, or a sign of an underlying health problem. The nose contains a rich network of tiny blood vessels, especially in the front part of the nasal septum (the “Kiesselbach’s plexus”). When these vessels are torn or become dilated, blood can escape into the nostrils, down the throat, or out of the nose.

Epistaxis can be classified as:

• Anterior nosebleeds – originate from the front of the nose; they are the most common (≈90 %).
• Posterior nosebleeds – arise deeper, near the back of the nasal cavity; they are less common but more likely to be severe.

While most episodes are harmless, understanding the causes, associated symptoms, and when to seek care is essential for safe management.

Common Causes

Below are the most frequently encountered triggers and medical conditions that can result in nosebleeds:

• Local trauma – picking or blowing the nose aggressively, facial injuries, or nasal surgery.
• Dry air – low humidity (common in winter or dry climates) dries the nasal mucosa and makes vessels fragile.
• Allergic rhinitis or upper‑respiratory infections – inflammation and frequent nose rubbing increase bleeding risk.
• Medications – anticoagulants (warfarin, DOACs), antiplatelet agents (aspirin, clopidogrel), and nasal sprays (corticosteroids, decongestants) can impair clotting.
• Systemic bleeding disorders – hemophilia, von Willebrand disease, platelet function disorders.
• Hypertension – high blood pressure can stress delicate nasal vessels, especially in posterior bleeds.
• Structural abnormalities – deviated septum, nasal polyps, or tumors (benign or malignant).
• Substance use – cocaine, methamphetamine, or chronic alcohol use can damage nasal mucosa.
• Environmental irritants – smoke, chemical fumes, or high‑altitude exposure.
• Inherited vascular disorders – hereditary hemorrhagic telangiectasia (Osler‑Weber‑Rendu) causes fragile vessels throughout the mucosa.

Associated Symptoms

Other signs that may accompany a nosebleed help clinicians identify the underlying cause:

• Frequent sneezing or runny nose (allergic rhinitis, infection).
• Facial pain or pressure (sinusitis, nasal polyps).
• Visible blood clots or a steady stream of bright red blood.
• Blood in the throat, coughing, or vomiting (posterior bleed).
• Bruising or bleeding from other sites (suggests systemic coagulopathy).
• Headache, visual changes, or facial swelling (possible tumor or severe trauma).
• Signs of anemia (fatigue, pallor) with recurrent heavy bleeds.
• Fever, chills, or malaise (infection).

When to See a Doctor

Most nosebleeds resolve with simple first‑aid measures, but you should contact a healthcare professional if you notice any of the following:

• Bleeding lasts longer than 20 minutes despite firm pressure.
• Bleeding recurs more than twice within a month.
• Heavy bleeding that soaks through a tissue or gauze in 5 minutes.
• Bleeding from both nostrils or the back of the throat (possible posterior bleed).
• Accompanying symptoms such as severe headache, facial swelling, vision changes, or dizziness.
• History of bleeding disorders, recent heart surgery, or use of blood‑thinners.
• Signs of anemia (shortness of breath, rapid heartbeat, pale skin).
• Any trauma to the face or head.

Diagnosis

Evaluation starts with a focused history and physical exam, then may include targeted tests.

History

• Onset, frequency, and duration of bleeds.
• Recent nose trauma, medication list, and alcohol or drug use.
• Family history of bleeding disorders or vascular malformations.
• Associated symptoms (fever, sinus pain, bruising).

Physical Examination

• Inspect anterior nasal cavity with a nasal speculum and good lighting.
• Identify source (Kiesselbach’s area, posterior pharynx).
• Check blood pressure, heart rate, and signs of anemia.
• Examine ears, throat, and skin for other bleeding sites.

Investigations (as needed)

• Complete blood count (CBC) – evaluate anemia, platelet count.
• Coagulation studies (PT/INR, aPTT) – assess clotting function.
• Serum electrolytes & kidney function – especially if on anticoagulants.
• Imaging (CT or MRI) – if a tumor, sinus disease, or skull base fracture is suspected.
• Nasal endoscopy – performed by an ENT specialist to view posterior bleeding sites or vascular lesions.

Treatment Options

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

First‑Aid / Home Care (for mild, anterior bleeds)

1. Sit up and lean forward – reduces blood swallowing and pressure on vessels.
2. Apply firm pressure – pinch the soft part of the nostrils together for 10–15 minutes.
3. Cold compress – place a cold pack on the bridge of the nose to cause vasoconstriction.
4. After bleeding stops, avoid nose blowing or picking for at least 24 hours.
5. Use a humidifier or saline nasal spray to keep mucosa moist.

Medical Interventions

• Cauterization – chemical (silver nitrate) or electrical cautery of a visible bleeding point.
• Nasal packing – gauze, nasal tampon, or inflatable balloon devices to apply pressure for persistent bleeds.
• Topical hemostatic agents – e.g., tranexamic acid spray, oxidized cellulose.
• Systemic therapy – correction of coagulopathy (vitamin K for warfarin reversal, fresh frozen plasma or prothrombin complex concentrate for severe anticoagulant‑related bleeds).
• Endovascular embolization – interventional radiology technique for refractory posterior bleeds.
• Surgical ligation – rare; tying off feeding vessels when other measures fail.

Treatment of Underlying Causes

• Adjust or discontinue offending nasal sprays or anticoagulants (after physician guidance).
• Control hypertension with appropriate medication.
• Treat allergic rhinitis with antihistamines, intranasal steroids, and allergen avoidance.
• Manage chronic sinus disease or nasal polyps via saline irrigation, steroids, or surgery.
• Address hereditary bleeding disorders with factor replacement or desmopressin.

Prevention Tips

Many nosebleeds can be avoided with simple lifestyle and environmental changes.

• Humidify indoor air – aim for 40–60 % relative humidity, especially in winter.
• Apply a thin layer of petroleum jelly or saline gel inside the nostrils daily.
• Avoid nose picking, aggressive blowing, or heavy lifting during an active bleed.
• Stay well‑hydrated – adequate fluid intake keeps mucosal membranes moist.
• Use protective gear (helmets, face shields) during sports or high‑risk activities.
• If you take anticoagulants, have regular lab monitoring and discuss dose adjustments with your provider.
• Quit smoking and limit exposure to secondhand smoke or chemical irritants.
• Manage allergies with antihistamines or immunotherapy to reduce nasal irritation.
• Schedule routine ENT check‑ups if you have a known nasal structural issue or hereditary vascular disorder.

Emergency Warning Signs

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

• Bleeding that does not stop after 20–30 minutes of continuous pressure.
• Rapid blood loss causing faintness, weakness, or a drop in blood pressure.
• Bleeding from both nostrils or from the back of the throat (possible posterior bleed).
• Severe facial trauma with associated nosebleed.
• Signs of anaphylaxis (difficulty breathing, swelling of lips/tongue) after nasal spray or medication.
• Sudden, severe headache with nosebleed, especially if accompanied by visual changes or neurological signs (possible intracranial bleed).
