How might pregnancy affect my asthma?

ANSWER

A lot of hormone changes happen during pregnancy, and some of them can affect your lungs.

One-third of women find that their asthma improves during their pregnancy. One-third don’t notice any difference, and the final third of women feel that their asthma symptoms become harder to control. This is more likely to happen if your asthma is severe. If so, you may notice that your asthma flares up the most during weeks 29 through 36 of your pregnancy.
