For example; a condition called hyperemesis gravidarum can occur which is where you get excessive morning sickness.

Morning sickness occurs in about 8 out of 10 pregnant women, and in around 1-3 in every 100 pregnant women hyperemesis gravidarum occurs. If you have morning sickness you are at risk of dehydration, but with HG you can be incredibly unwell and it could even put your baby at risk
