Specialty. Pulmonology. Asthma is a common pulmonary condition defined by chronic inflammation of respiratory tubes, tightening of respiratory smooth muscle, and episodes of bronchoconstriction. [1] The Centers for Disease Control and Prevention estimate that 1 in 11 children and 1 in 12 adults have asthma in the United States of America. [1]
Asthma is a long-term inflammatory disease of the airways of the lungs. [ 4 ] It is characterized by variable and recurring symptoms, reversible airflow obstruction, and easily triggered bronchospasms. [ 9 ][ 10 ] Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath. [ 3 ]
