Asthma and Pregnancy
Asthma is the most common of the chronic disease that can cause complications in pregnancies.
About 1% of pregnant women have asthma. Even if your asthma is well-controlled prior to getting pregnant, it does not mean it will stay that way during pregnancy. In about 1/3 of women, asthma can worsen during pregnancy, mainly during the first and last trimester. One-third of pregnant women will experience no change in asthma while a third may even see their asthma improve.
