Pre-existing conditions that can affect pregnancy

If you are thinking about starting a family you and your partner should discuss any pre-existing health condition and any medication you are taking with your General Practitioner. 

Your General Practitioner may refer you to a specialist to discuss you and your baby’s health during pregnancy.

Conditions that may impact on planning to get pregnant:


Your asthma may worsen or remain unchanged during pregnancy, but for most women symptoms tend to increase during the last trimester of the pregnancy.


If you have type 1 or type 2 diabetes, you need a review of your diabetes and general health.


It is very important for you and your partner to look after and monitor your weight at an appropriate body mass index before, during and after pregnancy. The Blooming Together Program (external site) helps overweight women have a successful, healthy pregnancy.
