Asthma is a common medical condition that is estimated to affect 8.4% to 8.8% of pregnant individuals.1 Uncontrolled asthma during pregnancy has been associated with adverse outcomes such as preterm birth, low birth weight, and preeclampsia. Asthma exacerbations during pregnancy may result in presentation to the emergency department, hospitalization for treatment of exacerbations, and, rarely, death. In individuals who have known asthma at pregnancy, recent data revealed that 60% of them had no change in their asthma during pregnancy but 40% had worsening of their symptoms; no individuals had improvement in their asthma.2 This finding differs from the previous observation that one-third of patients experience improvement, one-third have no change, and one-third have worsening of symptoms. For some patients, the initial diagnosis of asthma can also be made during pregnancy.
