What is asthma?

Asthma is chronic disease that affects your airways. If you have asthma, the inside walls of your airways may swell in response to something you’re allergic to or find irritating.

What causes asthma?

The cause of asthma is unknown, but some people are more at risk than others. Risk factors include genetics, allergies, obesity and exposure to fumes, pollution, infections or tobacco smoke. Women and blacks also tend to have asthma more than other groups.

What are the symptoms of asthma?

Asthma can cause your airways to narrow, making it more difficult for your lungs to get air. Symptoms include wheezing, coughing (especially early in the morning or at night), chest tightness and shortness of breath. When your asthma symptoms become worse than usual, it's called an asthma attack. Severe asthma attacks may require emergency care, and they can be fatal. Not everyone with these symptoms has asthma.

How does Ohio State diagnose asthma?
