There are many different reasons why a pregnancy may be considered high-risk.
It may start as a high-risk pregnancy due to the health of the mother, an unknown condition the mother may have, or because there is a specific family history which makes it hard to carry a baby full term.
It may develop as the pregnancy unfolds. This could be due to any number of things such as cervical weakness, gestational diabetes or a genetic disorder of the baby.
Some of these can be addressed before you fall pregnant, and some will need to be addressed as they appear.
It’s important to engage an obstetrician you can trust and to ensure, whoever they are, you keep them informed of any symptoms you may experience or any concerns you may have.
