Asthma in Pregnancy

Asthma is an increasingly common problem during pregnancy. Mild and moderate asthma can be associated with excellent maternal and perinatal pregnancy outcomes, especially if patients are managed according to contemporary recommendations of National Asthma Education and Prevention Program. Severe and poorly controlled asthma may be associated with increased prematurity, need for cesarean delivery, preeclampsia, and growth restriction. Severe asthma exacerbations can result in maternal morbidity and mortality, and can have commensurate adverse pregnancy outcomes. The management of asthma during pregnancy should be based upon objective assessment, trigger avoidance, patient education, and step therapy. Asthma medications should be continued during pregnancy and while breast-feeding.
