Bronchoconstriction
Definition: Bronchoconstriction is a condition typically found in asthmatics. When a reaction to a stimulant occurs, the smooth muscle that surrounds the airways in the lungs contracts or tightens, narrowing the airways and blocking the flow of air. Inflammation of the airways increases the narrowing, making it very difficult to breathe. This bronchoconstriction and inflammation typically leads to coughing, wheezing, and shortness of breath.
