Bronchospasm is a tightening of the smooth muscle that lines the airways (bronchi or bronchioles) in the lung. This tightening can contribute to a worsening of asthma symptoms, such as wheezing, shortness of breath, and coughing.

Bronchospasm can usually be relieved with medicines called bronchodilators.

This condition is also called bronchoconstriction or bronchial spasm.
