Allergic Rhinitis (Hay Fever): Causes, Symptoms, and Treatment

Allergic rhinitis, commonly known as hay fever, is an allergic reaction that triggers sneezing, nasal congestion, itchy nose, and watery eyes. It is caused by allergens such as pollen, pet dander, mold, and insects. While hay fever can make you feel uncomfortable, relief is possible through:

Lifestyle Changes: Avoiding allergens and maintaining a clean environment.
Allergy Medications: Antihistamines, nasal sprays, and decongestants.
Immunotherapy: Allergy shots that help reduce sensitivity over time.

What is Allergic Rhinitis (Hay Fever)?

Allergic rhinitis, also known as hay fever, is an allergic reaction caused by tiny airborne particles called allergens. When these allergens enter your body through the nose or mouth, your immune system releases a natural chemical called histamine to fight them. Despite the name, hay doesn’t cause hay fever, and it doesn’t lead to a fever.

Symptoms of Hay Fever:

Sneezing
Nasal congestion
Irritation in the nose, throat, mouth, and eyes

Difference Between Allergic and Nonallergic Rhinitis:

• Allergic Rhinitis: Triggered by allergens and involves histamine release.

• Nonallergic Rhinitis: Caused by inflammation, not allergens or histamine.

What Triggers Allergic Rhinitis (Hay Fever)?

Allergic rhinitis is triggered by both indoor and outdoor allergens. Common triggers include:
Pollen: From trees, weeds, and plants
Mold Spores
Pet Dander
Dust Mites
Cockroach Droppings and Saliva

When Do People Usually Get Hay Fever?

• Seasonal Allergies: Occur in spring, summer, and early fall due to higher pollen counts. However, pollen seasons may vary depending on location.

• Perennial Allergies: Happen year-round and are caused by indoor irritants like pet dander, cockroaches, and dust mites.

How Common is Allergic Rhinitis?

Hay fever is widespread. In the United States:
Around 20% of the population experiences allergic rhinitis.
In 2021, over 81 million people were reported to have seasonal allergies.

Symptoms and Causes of Allergic Rhinitis (Hay Fever)

What Are the Symptoms of Allergic Rhinitis?

Hay fever symptoms can occur year-round, but they may be worse during:

• Spring, Summer, and Early Fall: Pollen counts are higher as weeds and flowers bloom.

• Winter: Indoor allergens like pet dander and dust mites may worsen due to closed windows and increased indoor time.

Common Symptoms Include:

• Nasal stuffiness (congestion), sneezing, and runny nose

• Itchy nose, throat, and eyes

• Red or watery eyes

• Headaches, sinus pressure, and dark circles under the eyes

• Tiredness and fatigue

• Sore throat caused by mucus dripping down the throat (postnasal drip)

• Wheezing, coughing, and trouble breathing

How Do I Know If It’s Hay Fever or a Cold?

Although cold and hay fever symptoms are similar, here’s how to tell them apart:

✅ Allergic Rhinitis (Hay Fever):

• Symptoms occur at the same time each year or after exposure to allergens.

• Itchy, red, and watery eyes are common.

• Symptoms start quickly and persist until the allergen is gone.

❌ Common Cold:

• Caused by a virus and is contagious.

• Often includes muscle aches, pain, or fever.

• Usually goes away within a week, unlike allergies that persist.

What Causes Hay Fever (Allergic Rhinitis)?

Allergic rhinitis occurs when your immune system overreacts to tiny airborne irritants (allergens), mistakenly treating them as harmful. When these allergens enter your body through the nose or mouth, your immune system releases histamine, a chemical that triggers inflammation and itchiness in your nose, eyes, and throat to expel the allergen.

Common Allergens That Cause Hay Fever:

• Dust Mites: Found in carpets, drapes, bedding, and furniture.

• Pollen: From trees, grass, and weeds.

• Pet Dander: Tiny flakes of dead skin cells from pets.

• Mold Spores: Indoor and outdoor mold growth.

• Cockroach Saliva and Waste: A common indoor allergen.

⚠️ Note: Food allergies can also trigger inflammation in the nose and throat. Seek immediate medical attention if food allergies cause severe symptoms.

What Are the Risk Factors for Hay Fever?

Certain factors increase the likelihood of developing hay fever:

Family History: You’re more likely to have hay fever if a parent or close family member has allergies.
Asthma or Eczema: People with asthma or eczema are at a higher risk of developing hay fever.
Childhood Exposure: Early exposure to allergens can increase sensitivity over time.

💡 Tip: Understanding these risk factors can help in taking preventive measures to manage hay fever effectively.

Diagnosis and Tests for Hay Fever (Allergic Rhinitis)

How is Hay Fever Diagnosed?

Your healthcare provider will:

• Examine You: Evaluate your symptoms and rule out other conditions like a cold or asthma.

• Review Your Medical History: Check for a family history of allergies, asthma, or eczema.

Allergy Tests to Diagnose Hay Fever:

1. Blood Allergy Test (IgE Test):

   • Measures antibodies to allergens in your blood.

   • Detects most types of allergies, including food allergies.

2. Skin Prick Test:

   • A small sample of different allergens is placed on your skin (usually the forearm or back).

   • The skin is pricked or scratched with a needle.

   • If allergic, the area becomes red, itchy, and irritated within 15 to 30 minutes.

3. Intradermal Test:

   • A small amount of allergen is injected under the skin.

   • The skin reacts similarly to a prick test, confirming the allergen.

💡 Tip: These tests help identify specific allergens that trigger your hay fever, allowing for targeted treatment.

Management and Treatment of Hay Fever (Allergic Rhinitis)

How Do You Get Rid of Hay Fever?

Several treatment options can help improve symptoms and manage hay fever effectively. These include:

1. Antihistamines

• Block histamine release during an allergic reaction.

• Relieve nasal and sinus congestion.

• Available in oral (pill or liquid) and nasal spray forms.

• Common Decongestants:

  • Afrin® Nasal Spray

  • Phenylephrine Nasal Spray (Neo-Synephrine®)

  • Pseudoephedrine (Sudafed®)
