Can Allergies Cause Shortness of Breath

Allergies are a common issue that many of us face. They're not just about sneezing or itchy eyes; they can also affect how we breathe. Shortness of breath is a serious symptom often linked to allergies, and it's something we should all be aware of.

What is an Allergy?

Put simply, allergies happen when our body reacts to things it thinks are harmful but actually aren't. These can be things like pollen or particles in pet fur. When sensitive people breathe these in, their bodies may inappropriately launch an immune response. This leads to the production of histamines and other particles that can irritate the airways, making it harder to breathe.

How Do Allergies Impact Our Breathing?

We all love our furry friends, but sometimes, they can be the reason behind our allergies. The tiny bits of skin, known as dander, and proteins in their saliva and urine, can trigger allergic reactions. This is especially tough for those who already have conditions like asthma.

In cats, the main protein that causes allergies is called Fel D1, which is primarily found in their saliva. For dog lovers, the culprits are proteins known as Can F1 and Can F2. These allergens can lead to the usual allergy symptoms, but luckily, they don't usually cause shortness of breath. Knowing about these proteins is important because they are the key reasons behind the allergies and breathing problems that come with pet ownership.

On the other hand, seasonal allergies, like those caused by pollen, can also make breathing difficult. When pollen is in the air, people with allergies might find themselves short of breath or wheezing because of how their bodies react to these tiny particles.


If allergies are making it hard to breathe, there are things you can do. Over-the-counter medicines like antihistamines can help. In more serious cases, doctors might suggest using inhalers. It also helps to keep your home clean from allergens and use air purifiers.
