Diabetes during pregnancy

Sick days

Every day illnesses such as the flu and infections can cause your blood glucose levels to rise. If you get sick while you are pregnant, you will need to be particularly careful and check your blood  glucose levels more frequently.

You may also need to increase your insulin doses or have small frequent doses to prevent ketoacidosis. Make sure you have in-date ketone monitoring strips and that you know what to do if you find ketones present.

Talk to your diabetes health professionals about developing a sick day management plan, as this takes the guess work out of managing blood glucose levels when you are unwell.

Call your doctor or diabetes educator if you are vomiting or unable to eat or drink or if you are worried about high blood glucose levels.  

Managing sick days 

  • Follow your sick day management plan.
  • Check your blood glucose levels more frequently when you are unwell.
  • Take your insulin even if you are vomiting or not eating - talk to your diabetes health professionals about adjusting your insulin dose.
  • Check your urine or blood for ketones.
  • Call your doctor or diabetes educator if:
    • your urine ketone reading is more than 1+  
    • your blood ketone reading is more than 0.6 mmol/L
    • you are vomiting or unable to eat or drink
    • you are worried about high blood glucose levels
  • See your doctor to find out the cause of the illness.
  • Discuss hypo management with your diabetes health professionals.

If you are vomiting so much that you cannot keep food or fluids down, call your doctor or diabetes educator immediately or go to the Emergency Department of your nearest maternity hospital.
