Environmental allergies (also called allergic rhinitis or hay fever) occur when your immune system overreacts to substances in the air around you. Common triggers include pollen from trees, grasses, and weeds; dust mites; pet dander; and mold spores. When you breathe in these allergens, your body releases chemicals like histamine, causing symptoms like sneezing, congestion, and itchy eyes.

Environmental allergies are very common and affect millions of people across Colorado. They may be seasonal (worse during spring or fall) or year-round, depending on what you're allergic to.

Who is this service for?

Environmental allergy testing and treatment is right for you if you experience:

Persistent sneezing, especially outdoors or during certain seasons
Nasal congestion or a runny nose that won't go away
Itchy, watery, or red eyes
Itching in your nose, throat, or ears
Fatigue or difficulty sleeping due to allergy symptoms

If over-the-counter medications aren't helping, or if you're unsure what's triggering your symptoms, our specialists can help identify your specific allergens and create a personalised treatment plan.

What to expect during your visit

At Denver Allergy & Asthma Associates, your first appointment will include a detailed conversation about your symptoms, when they occur, and how they affect your daily life. We'll ask about your home environment, work setting, and outdoor activities to help pinpoint potential triggers.

We may recommend allergy testing to identify exactly which environmental allergens you're reacting to. Testing is quick, painless, and can be done right in our office. Results typically appear within 15-20 minutes, so you'll have answers the same day.

Treatment and management options

Once we know what you're allergic to, we'll discuss treatment options tailored to your needs:

Medications such as antihistamines, nasal sprays, or decongestants to manage symptoms
Environmental controls and lifestyle adjustments to reduce exposure to triggers
Immunotherapy (allergy shots or sublingual tablets) to gradually reduce your sensitivity to allergens over time
Asthma management if environmental allergies are triggering or worsening asthma symptoms

Many patients find that a combination of approaches works best. Your specialist will work with you to find the right balance for your lifestyle and preferences.

Understanding your environmental allergies Q & A

Environmental allergies develop when your immune system overreacts to airborne substances like pollen, dust mites, pet dander, or mold spores. Your body releases histamine in response, triggering sneezing, congestion, and itching. Genetics and exposure play a role in whether you develop these allergies.

We use skin prick testing, which is quick and painless. Small amounts of common allergens are applied to your skin, and we observe for reactions within 15-20 minutes. Results appear the same day, helping us identify exactly which environmental triggers affect you.

While there's no permanent cure, environmental allergies can be very effectively managed. Medications provide quick relief, and immunotherapy (allergy shots or tablets) can reduce your sensitivity to allergens over months or years. Many patients experience significant improvement with the right treatment plan.

Immunotherapy gradually exposes your immune system to small, increasing amounts of allergens to build tolerance. Over time, your body becomes less reactive to environmental triggers. It typically takes 3-5 years but can provide long-lasting relief, even after treatment ends.

Environmental allergies and asthma often occur together. Allergens can trigger or worsen asthma symptoms like coughing and shortness of breath. Our specialists assess both conditions and create integrated treatment plans to manage them together for better overall control.

Please bring your insurance card, a photo ID, and any medical records from other providers. It's helpful to keep a symptom diary for a week or two before your visit, noting when symptoms occur and what you were doing. This helps us identify patterns and triggers.
