First-trimester asthma exacerbations may lead to birth defects

In a study of 3,477 asthmatic women, those who had asthma exacerbations in the first trimester were 48 percent more likely to have a child with a congenital malformation: 13 percent of babies born to women with asthma attacks had at least one malformation, such as a birth defect of the heart, facial structures, spine or digestive system. That compared with 9 percent of infants whose mothers had well-controlled asthma in early pregnancy.' advice: "Women who are planning to become pregnant should make sure their asthma is under control. If it's not well-controlled, they should go to their doctor."

  1. It still hard to say that exacerbation cause birth defect. I think that it is caused by medication effect such as inhaled corticosteroid (Category C.) When you has an exacerbation you need more med and it leads to more birth defect.
