Symptoms can vary greatly. They can be barely noticeable or severe and life-threatening. Many people with asthma don’t even know they have it.

Symptoms vary depending on the individual and their age. One attack can also be different than another attack in the same person. You can go a long time without symptoms and have only periodic asthma attacks. Or you can have asthma symptoms on a daily basis, only at night, or only after exercise.

If you’re experiencing what you think might be asthma symptoms, see your doctor for asthma screening and tests.
