Evaluation of asthma course in pregnancy

The prevalence of asthma has been rising in recent decades. It is the most common disease among pregnant women andaffects ca. 12% of this population. The course of asthma in pregnancy may change. In 1/3 of patients, it worsens; in 1/3 ofpatients, the symptoms are milder; in 1/3 of patients, it remains unchanged. Well-controlled asthma decreases the risk ofpregnancy complications. Uncontrolled and severe asthma increases the risk of congenital malformations and obstetricalcomplications for both mother and baby. Exacerbations may also contribute to poor pregnancy outcomes. These occur mostlyeither in the first or in the second trimester. The most common triggers are viral infections and treatment non-compliance.The key to maintaining and gaining control of asthma is active treatment of asthma and its exacerbations.
