Might somebody have asthma and not have asthma attacks?

Yes: Asthma symptoms are cough, wheeze, chest tightness and shortness of breath. These symptoms can range from mild to severe. A person doesn't have to have an attack, the symptoms could be rather mild and intermittent. An allergist or pulmonologist can assess a persons asthma and determine the severity, control and best treatment approach.

Asthma: Asthma is a respiratory condition that can cause breathing problems through narrowing of airways and increased production of mucus. As stated earlier some people have mild asthma and just find it annoying. Some people only have intermittent symptoms.
