Bronchospasm is a tightening of the muscles in the walls of the bronchial tubes, which are the airways that carry air to and from the lungs. This can cause the airways to narrow, making it difficult for air to flow in and out of the lungs. Bronchospasm is often a symptom of asthma, but it can also be caused by other respiratory conditions or irritants such as smoke or pollution. Symptoms of bronchospasm can include coughing, wheezing, shortness of breath, and chest tightness or pain. Bronchospasm can be treated with bronchodilator medications that help to relax the muscles in the airways and open them up, allowing air to flow more easily. In severe cases, oxygen therapy may be needed to help the person breathe.
