What is Asthma?

asthmaAsthma is word which describes a process which is going on in the lungs.

Although it is defined as ‘reversible bronchoconstriction’ – we know that inflammation is also playing a very important role in many cases.

People who have asthma will often describe symptoms of chest tightness, shortness of breath, persistent cough, and/or wheezing. These symptoms may occur together or by themselves.

It can be a lifelong medical problem which needs to be diagnosed and managed, or it can be an infrequent, sporadic or even one time event.

Viral infections, allergies, exercise, cold air, sometimes medications or foods, or environmental exposures can all be triggers for either new onset asthma, acute asthma, or an exacerbation of chronic asthma.
