How do asthma symptoms change during pregnancy?

In general asthma symptoms do not worsen nor improve during pregnancy. There are several changes to respiration (breathing) that happen during pregnancy. As the uterus enlarges the lung volume decreases. There are several physiologic changes that occur that allow the pregnant woman to get adequate amounts of oxygen, and there are some that can potentially make asthma exacerbations worse. Thus it is important to ensure good control and preventative care of asthma during pregnancy.

The severity of asthma symptoms may change during pregnancy. Hormonal shifts affect asthma symptoms in pregnant women. For about one-third of pregnant women, asthma symptoms generally seem to worsen, while one-third may be lucky and see an improvement. Another third seem to have no change in the severity of their asthma.
