Can I Develop Hay Fever Over Time?

If you have recently found yourself sneezing more often or feeling itchy in your eyes and throat when the seasons change, you might wonder, "Can I develop hay fever over time?" The short answer is yes, and many people experience symptoms later in life, even if they have no previous allergy issues. Let’s jump into why that might be the case and how an allergy blood test can help you identify and manage this condition.

What is Hay Fever?

Hay fever, also known as allergic rhinitis, is an allergic response to airborne allergens like pollen, dust mites, and mould spores. It can affect anyone, regardless of age, although many people develop it during childhood or adolescence. The classic symptoms include:

• Sneezing
• Nasal congestion
• Runny nose
• Itchy eyes, nose, and throat
• Watery eyes

These symptoms occur when your immune system overreacts to allergens in the environment. As the immune system encounters these triggers, it releases histamines and other chemicals, causing inflammation and the familiar hay fever symptoms.

Can You Develop Hay Fever Later in Life?

Yes, you can develop hay fever over time, even if you had no allergy symptoms before. This phenomenon, known as adult-onset allergies, is becoming increasingly common. Some people might experience mild symptoms initially, which can gradually worsen with repeated exposure to allergens.

Factors Contributing to Late-Onset Hay Fever:

• Environmental Changes: Moving to a new location with different flora and allergens can trigger hay fever in adults.
• Immune System Changes: Natural ageing processes or lifestyle changes can make the immune system more sensitive to allergens.
• Previous Exposure: Past exposure to allergens may not have caused symptoms, but repeated exposure can sensitise the immune system over time.
• Genetics: A family history of allergies can increase the likelihood of developing hay fever.

Genetic Susceptibility

Around a third of adults in the Western world are thought to be potentially susceptible to developing an allergy, and this is written into our genes. However, that does not mean these people will go on to develop allergic symptoms.

Dr. Runa Ali explained, “Most people only carry antibodies to viruses and bacteria, but a third of people also carry antibodies to common things such as pollen or peanuts. However, of this number, only half will go on to develop real-life symptoms.”

A lot is still unknown about what exactly can cause an allergy to flare up in later life, but experts have plenty of theories.

“Hypotheses about what might shake up your immune system include suffering a severe infection like pneumonia, being exposed to pollution, or going through hormonal changes,” Dr. Ali said.

“However, even if we identified the people who were susceptible, it wouldn’t give us any warning about who will end up being allergic and who wouldn’t. In fact, if you were positive to a certain allergen, you might avoid it, but exposing yourself might keep you tolerant!”

Other Possible Triggers

• Lifestyle Changes: Moving to a large city with higher pollution levels or changing your diet can trigger allergies.
• Dietary Factors: Some meat and dairy products, as well as alcohol, contain histamines or trigger histamine release in the body.

Importance of Allergy Blood Tests

When suspecting hay fever, it’s crucial to identify the exact allergens causing your symptoms to manage them effectively. An allergy blood test is a helpful tool for this purpose. Here's why:

What Is an Allergy Blood Test?

An allergy blood test measures the presence of specific antibodies called Immunoglobulin E (IgE) in your blood. IgE antibodies are produced in response to allergens. The test provides insights into which allergens are causing your symptoms, whether it's pollen, dust mites, or other triggers. The benefits of taking a blood test are:

• Identifies Specific Allergens: Helps pinpoint the exact allergens causing your symptoms.

• Non-Invasive: Involves a simple blood draw with minimal discomfort.
• Broad Detection: Can detect a wide range of allergens in a single test.
• Suitable for All Ages: Ideal for those who can't undergo skin prick tests, such as infants or people with certain skin conditions.

How Is the Test Conducted?

1. Preparation: No special preparation is required, but inform your doctor about any medications you're taking.
2. Blood Draw: A healthcare professional will draw a small blood sample from your arm.
3. Lab Analysis: The blood sample is analysed in a laboratory to detect IgE antibodies for various allergens.
4. Results Interpretation: A healthcare provider will explain the results, indicating which allergens you're sensitive to and providing guidance on managing your condition.

Managing Hay Fever with Allergy Blood Test Results

Once you've identified the specific allergens causing your hay fever through an allergy blood test, managing your symptoms becomes more targeted and effective.

Practical Tips for Hay Fever Management:

Avoid Allergens:

• Stay indoors during high pollen count days.
• Keep windows closed during peak pollen hours.
• Use air conditioning with HEPA filters.
• Shower and change clothes after outdoor activities.

Medications:

• Antihistamines: Reduce sneezing, itching, and runny nose.
• Nasal Sprays: Relieve nasal congestion.
• Decongestants: Reduce nasal swelling and congestion.

Immunotherapy:

• Consider allergy shots or sublingual tablets if medications are ineffective.
• Natural Remedies:
• Use saline nasal rinses.
• Drink herbal teas like chamomile or peppermint.
• Apply cold compresses to itchy eyes.

Seek Medical Advice:

• Consult an allergist or healthcare provider for personalised recommendations.

Why Allergy Testing Is Crucial

An allergy blood test is a game-changer for understanding and managing hay fever. Without knowing your specific triggers, it's challenging to control symptoms effectively. Here’s why this test is essential:

• Tailored Treatment: Enables doctors to create a personalised treatment plan.
• Reduced Misdiagnosis: Differentiates between allergies and other conditions with similar symptoms, such as colds or sinus infections.
• Long-Term Relief: Helps develop long-term strategies like immunotherapy.

When to Seek Medical Help

If your hay fever symptoms interfere with daily activities or if over-the-counter medications don't provide relief, consult a healthcare provider. They may recommend an allergy blood test to identify your triggers and suggest appropriate treatment options.

By taking proactive steps and working with your healthcare provider, you can enjoy the outdoors and your daily life with fewer disruptions. If you suspect you may have developed hay fever, don't hesitate to discuss your symptoms with a healthcare professional and consider an allergy blood test. Knowing your triggers is the first step toward finding effective relief.
