Signs You Could Have Allergic Asthma

You’ll likely have symptoms of both allergies and asthma at once

Tired of constantly sneezing? Allergies alone can make you pretty miserable. But sometimes, what triggers allergies can wreak even more havoc — in the form of asthma.

When you develop sneezing, wheezing and shortness of breath all at once, you may have allergic asthma. Allergic asthma is the most common type of asthma, affecting about 25 million people in the United States.

Allergist and immunologist Ronald Purcell, MD, explains what allergic asthma is and how to manage your symptoms.

What is allergic asthma?

So, what is allergic asthma? When your allergies combine with asthma, it’s known as allergic asthma. This causes your airways to tighten whenever you breathe in an allergen.

While many different allergens can trigger allergic asthma, they all have one thing in common: They’re in the environment, not in your food or your medication.

These can include:

If pollen or mold trigger the condition, it may occur only seasonally. If your pets or the dust mites on your bedding trigger it, you may have symptoms year-round, Dr. Purcell notes.

Signs and symptoms

So, what allergic asthma symptoms should you look for?

Allergic rhinitis, or hay fever, affects your nose and sinuses. It may cause the following symptoms:

  • Sneezing.
  • Congestion.
  • Itchy nose and eyes.

Asthma mainly affects your lungs. It may cause the following symptoms:

  • Coughing.
  • Wheezing.
  • Chest tightness.
  • Shortness of breath or rapid breathing.

But when you have allergic asthma, you’ll likely develop both sets of symptoms at once.

In children, the symptoms of allergic asthma can be more subtle, notes Dr. Purcell. Kids might say they’re too tired to play, but parents should check for wheezing or coughing.

“If the other kids are running around playing, and your child wants to sit on the sidelines, they may be having trouble breathing,” he says.

How to help treat and manage symptoms

Allergy testing can help identify what’s triggering your allergies. Additional testing can help to confirm a diagnosis of asthma.

Once you know you have allergic asthma, identifying and avoiding its triggers will help you control your symptoms.

“When possible, take measures to prevent or minimize exposure,” advises Dr. Purcell.

The same methods won’t work for all allergy triggers. For example, “dust mites aren’t airborne — but cat and dog dander is,” he says.

To reduce allergens in your home, Dr. Purcell recommends:

  • Using a high-efficiency particulate air (HEPA) filter to reduce airborne triggers.
  • Minimizing or eliminating pet exposure.
  • Using special dust mite covers on bedding and aiming for indoor humidity levels of 35% to minimize dust mite exposure.
  • Eliminating food sources for cockroaches by using sealed food containers and regularly cleaning kitchen floors and surfaces.
  • Changing clothes and showering after you come inside if you’re allergic to pollen, and closing doors and windows when pollen counts are high.

Although mold is more of an outdoor allergen, it can develop indoors if there’s an unwanted source of moisture (plumbing, roof or basement leaks are common sources of water intrusion).


“Addressing the water leak, then using a diluted bleach solution or a commercial cleaning product is usually sufficient,” says Dr. Purcell. “Extensive mold intrusion may require a professional mold removal service.”

But is allergic asthma dangerous? The good news is that today’s allergic asthma treatments — mainly medication and inhalers — are very effective.

“They’re relatively easy to use and have minimal side effects,” Dr. Purcell says. “When symptoms are more severe or don’t respond to other measures, allergy shots (allergen immunotherapy) is very effective.”

One option that shouldn’t be on the table is letting allergic asthma ruin your quality of life.

“The goal is to manage your condition so that it never limits the activities you love because they trigger an allergic reaction,” says Dr. Purcell.

Working with your doctor will help you find a treatment plan that’s right for you.
