Diabetes during pregnancy

Sick days

Everyday 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.

If you are taking insulin, you may also need to adjust your doses to manage your blood glucose levels.

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.

Download a copy of the ADEA consumer resource Sick Day Management of Adults with Type 2 Diabetes and the Sick Day Action Plan to discuss with your diabetes in pregnancy team.   

Managing sick days 

  • Follow your sick day management plan.
  • Check your blood glucose levels more frequently when you are unwell.
  • If you are on insulin, continue to take it but talk to your doctor or diabetes educator about adjusting your insulin dose if you are vomiting, not eating or if your blood glucose levels are higher than usual.
  • If you are taking metformin, you may need to stop taking this medication temporarily if you have severe vomiting - ask your doctor for advice.
  • Call your doctor or diabetes educator if you:
    • are vomiting or unable to eat or drink
    • are worried about high blood glucose levels
    • need advice about your medication.
  • See your doctor to find out the cause of the illness.

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.
