What is Asthma?
Asthma is a chronic condition in which the airways tighten, swell, and produce extra mucus in response to triggers — making it hard to breathe. Symptoms range from occasional mild wheezing to frequent attacks that interfere with daily life. With an accurate diagnosis and a personalized plan, the vast majority of people with asthma live fully active lives.

How we diagnose it
We confirm asthma and measure how well your lungs are working with breathing tests.
Treatment options
The goal is good control — few symptoms, no limits on activity, and a clear plan for flare-ups.
Frequently asked questions
Is asthma the same as COPD?
No. Both affect the airways, but asthma is usually reversible and trigger-driven, while COPD involves more permanent change. Telling them apart guides treatment — and breathing tests help.
Can adults develop asthma?
Yes. Asthma can begin at any age, and adult-onset asthma is common. New wheezing or cough deserves evaluation.
