Here's some insight into what may be causing your sneezing and wheezing.

If you've had trouble breathing during allergy season, you may have wondered what's really going on. Is it asthma, allergies or both? The two conditions are closely connected and often happen together, which can make it hard to know what's causing your symptoms.  

Understanding the differences between asthma and allergies can help you recognize what's behind your symptoms and makes it easier to know when it's time to see a doctor.

What Are Allergies?

Allergies happen when your immune system reacts to something that's normally harmless. These triggers, called allergens, may include pollen, pet dander, mold, dust mites or certain foods.

When someone with allergies breathes in or touches these triggers, the body releases chemicals called histamines. This causes the symptoms many people experience, including sneezing, a runny or stuffy nose, itchy or watery eyes, a scratchy throat and skin rashes or hives. While allergies can make breathing uncomfortable, they usually affect the nose, eyes and skin more than the lungs.

Symptoms often show up soon after exposure to a trigger.

What Is Asthma?

Asthma is a chronic lung condition that affects the airways. In people with asthma, the airways become inflamed and narrow. This makes it harder for air to move in and out of the lungs. Asthma symptoms may include wheezing, shortness of breath, chest tightness and frequent coughing, especially at night or early morning. These symptoms happen because the muscles around the airways tighten and the lining inside the lungs becomes swollen.

Asthma attacks can be triggered by several things including exercise, cold air, respiratory infections, smoke and allergens like pollen or dust.

What's Causing Your Symptoms? Asthma or Allergies?

When allergens irritate the body, they can trigger inflammation in the airways. This may lead to asthma symptoms such as wheezing or breathing difficulty. Because of this, people sometimes assume their symptoms are just allergies when they may be experiencing asthma.

If your symptoms mainly involve the nose, eyes or skin, allergies are more likely the cause. Allergy symptoms also tend to come and go depending on your environment.

You may be dealing with allergies if you notice:

• Frequent sneezing
• Itchy or watery eyes
• A runny or congested nose
• Symptoms that appear after exposure to pollen, pets or dust

Asthma usually involves the lungs and breathing rather than the nose or eyes.

Possible signs of asthma include:

• Wheezing or a whistling sound when breathing
• Shortness of breath
• Tightness or pressure in the chest
• A cough that worsens at night or during exercise

When to See a Doctor

Because asthma and allergies can happen together, it's not always easy to tell them apart on your own. But if breathing feels difficult or symptoms keep returning, it's time to see a doctor.

Getting the right diagnosis is important. Allergy treatments often focus on avoiding triggers and using medications like antihistamines or nasal sprays. Asthma treatment may involve inhalers that help open the airways and reduce inflammation. Early treatment can help prevent symptoms from getting worse and make breathing much easier. And with the right care and treatment plan, most people with either condition can manage their symptoms and stay active year-round.
