Diabetes during pregnancy

Blood glucose monitoring

It is essential to monitor your blood glucose levels frequently during your pregnancy. You will be asked to test before meals and one to two hours after meals. You may, at times, be advised to do some extra monitoring, such as before bed and overnight (to look for hypos).

Monitoring will help you and your doctor to get a better understanding of your blood glucose levels, so you can adjust your insulin to achieve the best possible management of your diabetes. Extra blood glucose testing can also help you reduce the tendency to have hypos and big swings in your blood glucose levels.

Continuous Glucose Monitoring (CGM) may be suggested during your pregnancy. CGM uses a sensor placed under the skin to continually detect changes in glucose levels and to provide additional information about glucose patterns. This can be useful, but does not replace the monitoring you do yourself. Ask your diabetes in pregnancy team for more information.
