Allergic Rhinitis (Sensitive Nose) Specialist in Singapore

What is allergic rhinitis?

Allergic rhinitis, often called hay fever or a “sensitive nose”, is a nasal inflammation due to an allergic response to specific allergens such as pollen, dust mites, pet dander, and mold spores. This is a common condition in Singapore where high humidity and diverse flora can increase allergen exposure. Allergic rhinitis is affecting 13% of Singapore’s population, particularly children aged 4 to 17 years old. If your nose is sensitive, you might experience symptoms like sneezing, having a stuffy or runny nose and itchy eyes.

Types of Allergic Rhinitis

There are two main types of allergic rhinitis:

Seasonal allergic rhinitis (hay fever)

Triggered by outdoor allergens such as pollen. Less common in Singapore due to limited pollen seasons.

Perennial allergic rhinitis

More common locally, caused by year-round allergens such as house dust mites, cockroach droppings, mould spores, and pet dander.

Causes of Nose Allergies

Common causes of nose allergies include:

Pollen: Seasonal pollen from trees, grasses, and weeds.
Dust Mites: Tiny organisms found in dust, bedding, and upholstery.
Mold Spores: Grow in damp areas, releasing spores that trigger allergies.
Pet Dander: Proteins found in pet skin flakes, urine, and saliva.
Smoke and Strong Odors: Irritants that can trigger allergic responses.
Air Pollution: Environmental pollutants that can worsen nasal allergies.

Symptoms of Allergic Rhinitis

People with a sensitive nose due to allergic rhinitis may experience the following symptoms shortly after exposure to allergens:

As allergic rhinitis and sinusitis both have similar symptoms in the early stages but the difference will show over time. A clear distinction is that nasal drainage of allergic rhinitis is clear while sinusitis is often associated with large amounts of yellow or green mucus. Allergic rhinitis symptoms typically subside within a few days once the allergen is removed. If the symptoms persisted for more than 12 weeks, it may indicate sinusitis.

Risk Factors for Allergic Rhinitis

Certain factors increase the risk of developing allergic rhinitis:

Family history of allergies, asthma, or eczema
Living in humid environments with high dust mite exposure
Exposure to second-hand smoke or environmental pollutants

Having other allergic conditions such as asthma or sinusitis

Occupational exposure to dust, fumes, or chemicals

Don’t let constant sneezing or nasal congestion affect your daily life. Book an appointment with Dr Dennis Chua for evaluation and treatment of allergic rhinitis.

Diagnosis of Allergic Rhinitis

An ENT specialist may use the following methods to diagnose allergic rhinitis:

Clinical examination

Review of symptoms and physical inspection of the nasal passages.

Nasal endoscopy

A thin scope is used to assess the nasal lining for inflammation or polyps.

Allergy testing

Skin prick tests or blood tests can help identify specific allergen triggers.

Blood Tests

A blood test can measure the levels of immunoglobulin E (IgE) antibodies in your blood. These antibodies are associated with allergic reactions. Elevated IgE levels can indicate an allergic basis for your rhinitis and help identify potential allergens.

Allergy Panels

In some cases, your doctor may recommend a comprehensive allergy panel. This involves testing your blood or skin’s reaction to a wide range of potential allergens, providing a more detailed picture of your sensitivities.

Imaging studies

In recurrent or complicated cases, a CT scan may be used to rule out sinus disease.

Treatment of Sensitive Nose

Treatment for a sensitive nose depends on the underlying cause, most commonly allergic rhinitis. The goal is to reduce nasal inflammation, relieve symptoms, and minimise exposure to triggers.

Lifestyle and Environmental Modifications

Avoid allergens and irritants such as dust, pollen, smoke, and strong perfumes.
Use air purifiers and humidifiers at home to maintain clean and comfortable air quality.
Regular nasal hygiene with saline sprays or rinses can help flush out allergens and reduce irritation.

Medications for Allergic Rhinitis

Antihistamines: Reduce sneezing, itching, and runny nose by blocking allergic reactions.
Nasal corticosteroid sprays: Relieve inflammation and congestion effectively in chronic cases.
Decongestants: Short-term relief for blocked nose, but not suitable for prolonged use.
Leukotriene receptor antagonists: May be prescribed in selected cases to control allergic symptoms.

Immunotherapy

For patients with severe or persistent allergic rhinitis, allergen immunotherapy (allergy shots or sublingual tablets) may be recommended. This treatment gradually desensitises the body to allergens, reducing long-term sensitivity.

Medical Procedures

If medications and lifestyle changes are not effective, procedures may be recommended:

Radiofrequency turbinate reduction to reduce swollen nasal tissues.
Endoscopic sinus surgery if nasal polyps or structural problems worsen sensitivity and blockages.

Complementary Measures

Staying hydrated and practising good sleep hygiene can improve overall nasal comfort.
Wearing masks outdoors during high-pollen seasons may reduce allergen exposure.

Prevent Allergies

Preventing allergies involves a combination of proactive measures and lifestyle adjustments. Here are some tips to help you minimize your exposure to allergens and reduce the risk of allergy flare-ups:

1. Identify and Avoid Triggers

Keep a detailed diary to track your symptoms and identify potential allergens. This can help you pinpoint specific triggers and take steps to avoid them. Common allergens include pollen, dust mites, pet dander, mold, and certain foods.

2. Maintain a Clean Environment

Regularly clean your home to reduce allergens. Vacuum carpets and upholstery with a HEPA filter vacuum cleaner, dust surfaces frequently, and wash bedding in hot water to eliminate dust mites. Consider using air purifiers with HEPA filters to further improve indoor air quality.

3. Practise Good Hygiene

Wash your hands frequently, especially after being outdoors or touching pets, to remove allergens from your skin. Shower and change clothes after spending time outdoors, particularly during high pollen seasons, to avoid bringing allergens indoors.

4. Manage Indoor Air Quality

Use exhaust fans in kitchens and bathrooms to reduce humidity and prevent mold growth. Ensure proper ventilation in your home by opening windows regularly, especially during dry weather. Consider using dehumidifiers in damp areas to control humidity levels and discourage dust mites.

5. Consider Allergy-Proofing Your Home

Use allergen-proof covers on pillows, mattresses, and box springs to reduce exposure to dust mites. Opt for hardwood or tile flooring instead of carpets, which can trap allergens. If you have pets, keep them out of bedrooms and off furniture to minimize dander exposure.

6. Consult an Allergy Specialist

If your allergies are persistent or severe, consult an allergy specialist or ENT doctor. They can conduct tests to identify specific triggers, provide personalized advice, and recommend appropriate treatments or preventive measures, including immunotherapy (allergy shots).

7. Stay Informed

Stay updated on local pollen counts and weather forecasts, especially during allergy seasons. Many weather apps and websites provide pollen information, which can help you plan outdoor activities and take necessary precautions.
