Allergies & Allergic Rhinitis:Symptoms, Causes, Types, Treatment & When to See an ENT Doctor
Allergies can cause repeated sneezing, nasal blockage, runny nose, itching, watery eyes and post-nasal drip. Understanding your triggers and choosing the right treatment can help control symptoms and improve breathing, sleep and everyday comfort.
Understanding Allergies
What Are Allergies?
An allergy occurs when the immune system reacts to a normally harmless substance called an allergen. Common allergens include pollen, house dust mites, mould and animal dander.
called allergic rhinitis. It may cause sneezing, nasal itching, a runny or blocked nose and itchy or watery eyes.
Allergy symptoms can sometimes resemble a cold or other nasal conditions. A proper assessment can help identify whether the symptoms are allergic, infectious, structural or related to another cause.
Allergic Rhinitis
Allergy-related inflammation inside the nose causing sneezing, itching, runny nose or blockage.
Trigger Management
Identifying and reducing exposure to relevant allergens can be an important part of long-term allergy control.
Allergy-Related Conditions
Common Allergy & Nasal Allergy Problems
Allergies can affect the nose, eyes, throat and breathing. The symptoms and treatment approach can vary depending on the underlying trigger.
Allergic Rhinitis
An allergic reaction inside the nose that may cause repeated sneezing, itching, runny nose and nasal blockage after exposure to an allergen.
Seasonal Allergies
Allergy symptoms that occur during particular seasons, commonly triggered by pollen from trees, grasses or weeds.
Dust & Dust Mite Allergy
A common indoor allergy that can cause persistent sneezing, nasal congestion, itching and post-nasal drip.
Pet Allergy
Allergic reactions associated with exposure to proteins from pets, including particles from skin, saliva or urine.
Mould Allergy
Exposure to mould particles may trigger nasal and respiratory allergy symptoms in susceptible individuals.
Post-Nasal Drip
Excess mucus draining into the throat can cause throat clearing, cough, irritation and a sensation of mucus at the back of the throat.
Allergy-Related Nasal Blockage
Inflammation of the nasal lining can make breathing through the nose difficult, particularly during allergy flare-ups.
Allergic Eye Symptoms
Allergies may cause itchy, red or watery eyes along with nasal symptoms, especially during seasonal allergy episodes.
Non-Allergic Rhinitis
Nasal symptoms can sometimes occur without an allergy and may be triggered by smoke, strong smells, temperature changes or other irritants.
Allergy & Sleep Problems
Persistent nasal blockage and congestion can interfere with comfortable nasal breathing and sleep quality.
Recognising Allergy Symptoms
How to Identify an Allergy?
Allergy symptoms often appear after exposure to a particular trigger. Keeping track of when symptoms occur, where they occur and what seems to trigger them can help during a medical consultation.
However, allergy symptoms can overlap with infections, non-allergic rhinitis and structural nasal problems. Persistent or unclear symptoms may require an ENT assessment.
Common Allergy Triggers
What Can Trigger Allergies?
Allergy triggers vary from person to person. Common triggers include pollen, house dust mites, mould and animal dander.
Pollen
Tree, grass and weed pollen may trigger seasonal allergy symptoms.
House Dust Mites
A common indoor trigger associated with persistent nasal allergy symptoms.
Animal Dander
Exposure to proteins associated with pets can trigger allergic reactions.
Mould
Mould particles can trigger allergy symptoms in susceptible individuals.
Types
Types of Allergies & Rhinitis
Seasonal Allergic Rhinitis
Symptoms that occur during particular seasons, often associated with pollen.
Perennial Allergic Rhinitis
Symptoms that may continue throughout the year because of persistent indoor or environmental triggers.
Occupational Allergy
Symptoms associated with exposure to specific substances in a work environment.
Non-Allergic Rhinitis
Nasal symptoms caused by irritants or other triggers rather than an allergic reaction.
Diagnosis
How Are Allergies Diagnosed?
Diagnosis starts with a detailed history of symptoms, possible triggers, duration and response to previous treatment. A doctor may also examine the nose, throat and related structures.
If the cause is unclear or symptoms are significant, allergy testing may be considered. Depending on the situation, this may include skin-prick testing or blood tests.
Detailed allergy and symptom history
Nose, throat and ENT examination
Assessment of possible environmental triggers
Evaluation for associated sinus or nasal problems
Skin-prick testing when appropriate
Blood allergy testing when appropriate
Further ENT assessment for persistent nasal blockage
Treatment Approach
Allergy Treatment & Management
Treatment is selected according to the type of allergy, severity of symptoms, triggers and response to previous treatment.
Trigger Avoidance
Reducing exposure to known allergens can help prevent or reduce symptoms.
Antihistamines
Antihistamine medicines may help control symptoms such as sneezing and itching when appropriate.
Nasal Sprays
Nasal corticosteroid sprays may be used to reduce nasal inflammation and congestion.
Specialist Treatment
Selected patients with significant or difficult-to-control allergies may need specialist assessment and consideration of immunotherapy.
Important: Not every blocked or runny nose is caused by an allergy. Treatment should be based on the underlying cause. Antihistamines and nasal corticosteroid sprays can be useful for appropriate allergy symptoms, but medication choice and use should be discussed with a doctor or pharmacist when necessary.
Long-Term Impact
What Happens If Allergies Are Not Properly Managed?
Allergic rhinitis is usually manageable, but persistent symptoms can significantly affect everyday comfort, sleep and quality of life.
Persistent nasal congestion
Poor sleep or disturbed sleep
Frequent mouth breathing
Ongoing post-nasal drip
Repeated throat clearing or cough
Reduced daily comfort and concentration
Difficulty controlling symptoms
Possible worsening of associated asthma symptoms in some people
Medical Evaluation
When Should You See an ENT Doctor?
Consider an ENT evaluation when allergy or nasal symptoms continue despite appropriate treatment, interfere with sleep or daily activities, or when the cause is uncertain.
Emergency Allergy Warning Signs
A severe allergic reaction, known as anaphylaxis, requires immediate emergency medical treatment.
These symptoms can indicate anaphylaxis and require immediate emergency medical attention.
Patient Scenarios
Illustrative Allergy Case Examples
The following are illustrative examples showing how persistent allergy symptoms may be evaluated. They are not presented as individual patient records.
Persistent Sneezing & Nasal Blockage
A patient experiences repeated sneezing, nasal itching and blockage, particularly after exposure to dust. Evaluation focuses on identifying triggers and distinguishing allergic rhinitis from other causes of nasal obstruction.
Allergy Affecting Sleep
A patient has persistent nasal congestion, mouth breathing and disturbed sleep. ENT assessment can evaluate allergy, nasal anatomy and other possible causes of nighttime breathing difficulty.
Symptoms Despite Treatment
A patient continues to experience allergy symptoms despite using treatment. The next step may involve reviewing the diagnosis, trigger exposure, medication technique and whether specialist testing is appropriate.
