Asthma is a chronic, or long-term, disease of the lungs. In this section, you can find out about the anatomy of the respiratory system and how asthma affects it. We cover allergic and non-allergic asthma, as well as asthma classifications.

You can also find information on the warning signs and symptoms of asthma and how it’s diagnosed. Asthma mimickers, or conditions that present some of the same signs and symptoms as asthma, are also covered in this section.
