Well, I’ve written about my experiences with hypermobility in pregnancy and birth, and again about how my pituitary tumour impacted my pregnancy and birth. So it seems logical to write about how my asthma impacted me as well, and complete the trilogy… How did pregnancy affect my asthma?

My Experience of Asthma in Pregnancy

But I’ve been in two minds about writing this post, because actually my asthma barely affected me at all! In fact I noticed a massive improvement in my asthma symptoms while I was pregnant. Normally they’re worst around June; my asthma seems to be particularly triggered by hayfever and then made worse by humid weather. Last year when I was pregnant, I spent the end of May in Japan at a family wedding, and when I got back I realised my asthma seemed much better than usual. Seems strange, huh?

Does pregnancy make asthma better or worse?

I spoke to my asthma nurse about this recently when I went for a review (she’s the best! Shout out to all the awesome asthma nurses out there). She said that roughly a third of people with asthma notice an improvement of their symptoms in pregnancy, a third notice a deterioration, and for the rest there’s no change. So I guess I was one of the lucky 33%. I felt so crap being pregnant anyway, I’m so glad I didn’t have to deal with my asthma playing up too.

Why does pregnancy affect my asthma?

Looking online, there are plenty of asthma sites which also advise that asthma may improve or worsen in pregnancy. But none of them seem to explain why. I assume it’s the usual “pregnancy hormones” explanation, which is so vague as to be no explanation at all. So I’m awarding a gold star to any health professional who can let me know in the comments below why specifically it is that asthma is so variable in pregnancy!

Does asthma affect you when giving birth?

I also didn’t find that my asthma affected the birthing process, fortunately. As I have exercise-induced asthma, I did wonder whether labour could trigger my asthma at all. I took my inhalers to the hospital with me (make sure you have spares in your hospital bag just in case!). But luckily, I didn’t need them during the birth.

In fact, apparently asthma attacks during labour are very rare, which is believed to be because of the natural steroids that your body produces during labour. The Asthma UK website has more information about asthma and birth, which may also reassure you.
