Nosebleed (Epistaxis) Treatment in Singapore

What is a Nosebleed?

A nosebleed — known medically as epistaxis — is bleeding from the rich network of small blood vessels lining the inside of the nose. Around 60% of people will have at least one significant nosebleed in their lifetime, but only about 6% will need medical attention. In Singapore's air-conditioned offices, schools, and bedrooms, the threshold for needing professional treatment is reached more often than in temperate countries because dry air constantly irritates the nasal lining.

Doctors classify nosebleeds by where the bleeding originates:

• Anterior bleeds — about 90% of all cases. The bleeding comes from Little's area, a cluster of fragile vessels at the front of the nasal septum. The blood typically drips out of one nostril, is bright red, and responds well to first-aid pressure.
• Posterior bleeds — uncommon but more dangerous. Bleeding originates deeper in the nose, often from a branch of the sphenopalatine artery. Blood may run down the back of the throat as well as out of the nose. Posterior bleeds are more common in older adults, in patients on blood thinners, and in those with poorly controlled hypertension.

Symptoms and Warning Signs

• Active bleeding from one or both nostrils
• Blood trickling down the back of the throat (taste of iron, or coughing/spitting blood)
• Episodes lasting more than 20 minutes despite correct first-aid
• Recurrent bleeds — more than twice a week, or more than a few times a month
• Lightheadedness, palpitations, or pallor with heavy bleeding
• Persistent crusting, itching, or a "scab that keeps re-bleeding" inside one nostril
• Blood-stained mucus when blowing the nose, even between obvious bleeds

What Causes Nosebleeds in Singapore?

Singapore presents an unusual mix of nosebleed triggers. Outdoor humidity is high, but most of us spend our day in heavily air-conditioned offices, MRT trains, classrooms, and bedrooms — environments often drier than 40% relative humidity. The constant transition between humid outdoors and dry indoors strips moisture from the nasal lining and leaves microscopic fissures that bleed easily.

• Dry air-conditioned environments — by far the most common trigger we see in clinic, particularly in office workers and students who study in libraries
• Haze and PM2.5 — the July–September haze season inflames the nasal lining and triggers a wave of nosebleed presentations
• Allergic rhinitis — chronic inflammation makes the septal vessels fragile; treating the allergy reduces bleeds
• Nose picking — the leading cause in children aged 2–10
• Blood-thinning medication — aspirin, clopidogrel, warfarin, and the newer DOACs (apixaban, rivaroxaban, dabigatran)
• Deviated nasal septum — turbulent airflow over the deviation dries one side faster, producing recurrent one-sided bleeds
• Uncontrolled hypertension — does not start a bleed but makes one harder to stop
• Forceful nose blowing during a cold or sinus infection
• Less commonly — bleeding disorders, vascular abnormalities, and (rarely) tumours of the nose or nasopharynx

When Should You See an ENT Doctor?

You should book an ENT appointment if any of the following apply:

• A single nosebleed lasted longer than 20 minutes despite correct first-aid
• You have more than two nosebleeds per week, or more than four per month
• The same nostril keeps bleeding (suggests one identifiable problem vessel)
• You are on aspirin, warfarin, clopidogrel, or any DOAC
• Bleeds occur with no obvious trigger and you feel lightheaded
• You are an adult of South Chinese descent with persistent one-sided bleeds — nasoendoscopy is needed to exclude nasopharyngeal carcinoma
• A child has frequent bleeds that are difficult to control or that interrupt sleep
• Bleeding is accompanied by easy bruising elsewhere (suggests a clotting problem)

How are Nosebleeds Diagnosed?

The CENTAS workup for recurrent epistaxis is designed to identify the bleeding source and any underlying cause in a single visit:

• Detailed history — frequency, duration, side, triggers, medications, family history of bleeding disorders
• Blood pressure check — uncontrolled hypertension is a common contributor in adults over 50
• Anterior rhinoscopy — direct inspection of Little's area for prominent vessels, scabs, or septal deviations
• Nasoendoscopy — a thin flexible camera takes about a minute and visualises the entire nasal cavity, including posterior bleeding sites and the nasopharynx
• Blood tests where indicated — full blood count, clotting profile (PT/INR, APTT), particularly for patients on blood thinners
• Imaging (rare) — CT scan if a tumour or vascular malformation is suspected

Treatment Options for Nosebleeds in Singapore

In-Clinic Treatment

• Silver nitrate chemical cauterisation — a small applicator stick is touched to the bleeding vessel after a topical anaesthetic spray. The procedure takes under 5 minutes, requires no downtime, and is effective for the vast majority of anterior bleeds from Little's area.
• Electrocautery — for vessels too large or too brisk for chemical cautery; performed under local anaesthesia in clinic, or under general anaesthesia in theatre for posterior bleeds.
• Anterior nasal packing — a small dissolvable or removable pack is placed in the nostril for 24–48 hours to apply continuous pressure when cautery cannot be performed safely.
• Posterior packing — reserved for severe posterior bleeds; usually requires admission for monitoring.
• Treating the underlying cause — controlling allergic rhinitis with intranasal steroid spray, septoplasty for a symptomatic deviated septum, blood pressure optimisation, or coordinating with your cardiologist on blood-thinner management.

Day Surgery and Specialist Procedures

• Endoscopic sphenopalatine artery ligation (SPAL) — a definitive day-surgery procedure for severe or recurrent posterior bleeds. Performed under general anaesthesia at Mt Elizabeth Hospital, often Medisave-claimable.
• Septoplasty — straightening a deviated septum that is causing repeated bleeds on one side.
• Arterial embolisation — performed by interventional radiology for catastrophic posterior bleeds when surgery is not possible.

Prevention and Long-Term Care

• Apply a thin layer of saline gel or petroleum jelly to the inside of each nostril twice daily during dry seasons
• Use saline nasal sprays during the workday in air-conditioned offices
• Set bedroom air-conditioning no lower than 24°C; consider a bedside humidifier
• Treat allergic rhinitis properly with daily intranasal steroid spray rather than just antihistamines
• Avoid forceful nose blowing — blow gently, one nostril at a time
• Discourage children from nose picking; keep their fingernails short
• If you are on blood thinners, do not stop them yourself — discuss any persistent bleeding with your prescribing doctor
