Asthma, also called bronchial asthma, is a disease that affects your lungs. It’s a chronic (ongoing) condition, meaning it doesn’t go away and needs ongoing medical management.

Asthma affects more than 25 million people in the U.S. currently. This total includes more than 5 million children. Asthma can be life-threatening if you don’t get treatment.
When you breathe normally, muscles around your airways are relaxed, letting air move easily and quietly. During an asthma attack, three things can happen:

Bronchospasm: The muscles around the airways constrict (tighten). When they tighten, it makes your airways narrow. Air cannot flow freely through constricted airways.

Inflammation: The lining of your airways becomes swollen. Swollen airways don’t let as much air in or out of your lungs.

Mucus production: During the attack, your body creates more mucus. This thick mucus clogs airways.
