Allergic rhinitis, commonly known as hay fever, is an inflammation of the nasal passages triggered by exposure to allergens such as pollen, dust mites, mold, or animal dander. It affects millions worldwide and is one of the most common allergic disorders.
This condition causes sneezing, nasal congestion, runny nose, and itching, significantly impacting daily life. Although it’s not life-threatening, allergic rhinitis can lead to sleep problems, fatigue, and reduced concentration if left untreated.

Causes of Allergic Rhinitis: Why It Happens
Allergic rhinitis occurs when the immune system overreacts to harmless airborne substances. Upon exposure, the body releases histamine, a chemical that causes inflammation and irritation in the nasal passages.
The most common allergens include:
- Pollen: From trees, grasses, and weeds (seasonal allergic rhinitis).
- Dust mites: Microscopic organisms found in bedding and upholstery.
- Mold spores: Often present in damp environments.
- Animal dander: Tiny flakes of skin or saliva from pets.
- Air pollution and smoke: Can worsen symptoms in sensitive individuals.
Types of Allergic Rhinitis
Allergic rhinitis is typically classified into two main categories:
- Seasonal Allergic Rhinitis: Triggered by outdoor allergens such as pollen during specific seasons (spring, summer, or fall).
- Perennial Allergic Rhinitis: Occurs year-round and is usually caused by indoor allergens like dust mites, pet dander, or mold.
Some people experience both types, leading to constant or recurring symptoms throughout the year.

Common Symptoms of Allergic Rhinitis
The symptoms of allergic rhinitis can range from mild to severe and may affect both the nose and eyes. The most common include:
- Frequent sneezing
- Runny or stuffy nose
- Itchy eyes, nose, or throat
- Watery eyes (allergic conjunctivitis)
- Postnasal drip (mucus draining down the throat)
- Cough and fatigue due to poor sleep
- Reduced sense of smell in chronic cases
If left unmanaged, allergic rhinitis can lead to complications such as sinusitis, ear infections, or asthma flare-ups.
Diagnosis: How Allergic Rhinitis Is Detected
Doctors diagnose allergic rhinitis through:
- Medical history and symptom review
- Physical examination of the nasal passages
- Allergy testing, such as skin prick tests or specific IgE blood tests, to identify triggering allergens
Early diagnosis helps in effective management and reduces long-term discomfort.

Treatment and Management Options
Managing allergic rhinitis involves both preventive measures and medical treatment.
1. Avoidance of Triggers
The first step is identifying and minimizing exposure to allergens:
- Keep windows closed during high pollen seasons.
- Use air purifiers and dehumidifiers indoors.
- Wash bedding frequently in hot water to remove dust mites.
- Avoid pets if you’re allergic to animal dander.
2. Medications
Several medications can relieve symptoms effectively:
- Antihistamines: Reduce sneezing and itching (e.g., cetirizine, loratadine).
- Nasal corticosteroids: Control inflammation (e.g., fluticasone, mometasone).
- Decongestants: Relieve nasal blockage (short-term use only).
- Leukotriene inhibitors: For patients with both asthma and rhinitis.
3. Immunotherapy (Allergy Shots or Tablets)
For long-term relief, allergen immunotherapy helps desensitize the immune system. It’s especially useful for patients with severe or persistent symptoms that don’t respond to medication.
Lifestyle Tips for Relief
- Rinse nasal passages with saline solution regularly.
- Shower and change clothes after outdoor exposure to pollen.
- Keep indoor humidity below 50%.
- Maintain a balanced diet rich in vitamins C and E, which may help reduce inflammation.
When to See a Doctor
Seek medical advice if symptoms:
- Persist for more than a few weeks
- Interfere with sleep or daily activities
- Cause recurrent sinus infections or breathing difficulty
Early treatment can prevent chronic complications and improve quality of life.
