Your airways may swell, become more constricted, and create more mucus if you have asthma. Shortness of breath, coughing, wheezing when you exhale, and difficulty breathing can all result from this. Asthma might be a minor inconvenience for some people.
Inflammation and muscular contractions surrounding the tiny airways cause the airways in the lungs to become constricted. This results in asthma symptoms as coughing, wheezing, shortness of breath, and tightness in the chest. These intermittent symptoms are frequently worst at night or after activity.
