Can Allergies Cause Asthma?

For people living with allergy and asthma symptoms, it’s common to wonder how much the two conditions are related. Can allergies cause asthma and vice versa? Are there treatment options available to ease symptoms of both? What differences make these two different diagnoses? Perhaps most importantly, how can you manage these conditions together?

You can use a particular medication or take advantage of your favorite houseplants like snake plant to purify the air. Several treatments can help you manage both of these conditions and help you better understand the relationships between the two.


In children and adults alike, these common respiratory conditions manifest with symptoms like chest tightness, scratchy throat, sneezing, or wheezing. Usually, those symptoms are distinct, each associated with one ailment or the other. In some cases, though, the two aren’t so clear-cut. For example, for those dealing with both allergy and asthma symptoms, you might find that the two overlap with allergies most often triggering or intensifying asthma symptoms. 

The similarities in treatment may very well be the most obvious connection between these respiratory conditions. There’s a reason that an allergist may be your go-to specialist for asthma treatment. If you’re saving money with a Symbicort coupon to ease your asthma symptoms, you might find that the correct dose of Symbicort (or your preferred medication) can relieve your allergy symptoms, too. 

Even home remedies like purchasing an air purifier or bringing home floor plants to improve air quality can lead to better health despite dealing with both of these diagnoses. Many treatment options–including both lifestyle changes and medicine from your local pharmacy—will help both of these conditions, whether or not the pharmaceutical company markets it as such. 


Although specific treatments might ease allergies and asthma symptoms, the two conditions are not interchangeable. Perhaps most notably, the symptoms of allergies and asthma are noticeably different. Your allergies will typically cause issues like itchy eyes, runny nose, or hives and other rashes. Meanwhile, asthma symptoms include wheezing and breathlessness, chest tightness, and cough, particularly at night or at the start of the day. 

Because these symptoms are so different, these conditions are all the more blatantly separate. Still, we’re left with a question: can allergies cause asthma symptoms or vice versa? 

Allergy-Induced Asthma

In a diagnostic sense, allergies and asthma don’t cause one another. However, symptoms of one can exacerbate the signs of the other (just like the overlap in treatments can ease one while treating the other). The most blatant example of this is a condition known as allergy-induced asthma, in which reactions to seasonal or year-round allergens cause your symptoms. 

Conversely to the nonallergic variant, allergy-induced asthma symptoms are triggered by the allergens that bring on allergies, with factors like dust and pollen being some of the worst prompts. In this case, your treatment plan for one diagnosis will almost definitely ease the other, too. So whether your pharmacist hands you Symbicort each month or your doctor suggests adding indoor plants to your bedroom to treat sinusitis symptoms, allergy-induced asthma solutions will undoubtedly relieve both conditions—if only because of their inherent relationship. 

Allergy and asthma symptoms can severely impact your life, but they aren’t necessarily interchangeable. Many treatments will ease the signs of both conditions, even if they’re meant to relieve just one. For example, your medication or indoor garden just might alleviate a broad range of respiratory symptoms, easing both allergies and asthma in one fell swoop. And, if your asthma happens to be allergy-induced, you’ll be better able to understand your diagnoses and the relationship between them, giving you all the more control of your respiratory and overall health.
