What Is Allergic Rhinitis?
Allergic rhinitis is a common chronic condition that develops when the nasal mucosa becomes hypersensitive to allergens. It is also commonly known as "hay fever." It occurs when the immune system perceives harmless substances such as pollen, dust mites, pet dander, or mold as a threat.
What Causes Allergic Rhinitis?
The most common triggers are:
- Pollen (especially in spring and summer)
- House dust mites
- Pet dander
- Mold spores
- Cigarette smoke and air pollution
What Are the Symptoms?
- Persistent (clear) runny nose
- Nasal congestion
- Sneezing fits
- Itching in the nose and eyes
- Watery, red eyes
- Postnasal drip
Treatment
Treatment involves allergen avoidance along with medication.
Allergen Avoidance
- Reducing time outdoors during pollen season
- House dust control (regular cleaning of sheets and pillows)
- Reducing contact with pets
- Staying away from cigarette smoke
Medication
- Antihistamines: Reduce sneezing and itching.
- Corticosteroid nasal sprays: Control nasal congestion.
- Decongestants: Short-term nasal decongestants.
- Saline solution: Provides nasal cleansing.
Allergy Shots (Immunotherapy)
Used for long-term, treatment-resistant cases. The goal is to desensitize the immune system to the allergen.
What Happens If It's Left Untreated?
Left untreated, allergic rhinitis can lead to chronic nasal congestion, recurrent sinusitis attacks, and over time, turbinate hypertrophy (enlarged nasal turbinates). Prolonged mouth breathing can lead to poor sleep quality and daytime fatigue.
When Should You See an ENT Specialist?
- If symptoms last longer than 4 weeks
- If over-the-counter medications don't provide sufficient relief
- If accompanied by one-sided nasal congestion, bleeding, or loss of smell
- If sleep quality is significantly affected
- If symptoms in children are affecting daily life
Frequently Asked Questions
Are allergic rhinitis and sinusitis the same thing?
No. Allergic rhinitis is a hypersensitivity reaction of the immune system to allergens such as pollen, dust, or pet dander. Sinusitis is inflammation of the sinus cavities due to infection or inflammation. Allergic rhinitis can set the stage for sinusitis; the diagnosis and treatment of each are different.
Is surgery needed for allergic rhinitis?
Allergic rhinitis is primarily managed with medication (antihistamines, nasal corticosteroids) and allergen immunotherapy. If turbinate hypertrophy persists despite this, surgical reduction procedures may be considered.
Does allergic rhinitis occur in children?
Yes, it is common in childhood, and the risk increases with a family history of allergies. The treatment approach for children is determined by a specialist according to age.
Does allergic rhinitis go away permanently?
In some people it may decrease seasonally, while in others it can become chronic. Immunotherapy can reduce sensitivity over the long term, but a definitive cure cannot be guaranteed.
