Keeping a gestational diabetes blood sugar log

After a gestational diabetes diagnosis, you will usually be asked to check and log your blood sugar several times a day at home. Your log guides meal planning and treatment decisions.

Common targets

For after-meal checks, many clinics ask you to use either the 1-hour or the 2-hour time point. Targets and methods can differ between clinics, so your care team's targets always come first.

Usual daily check times

• One fasting check in the morning
• Three checks 1 or 2 hours after breakfast, lunch, and dinner

Four checks a day is a common schedule, but your clinic may ask for something different.

Also worth logging

• What and how much you ate, including snacks
• When you started eating (the start of your after-meal timer)
• Activity such as a walk after meals
• Prescribed treatment such as insulin

This article is general health information and does not replace diagnosis or treatment. Targets and how often to check differ from person to person, so follow your care team first. If you have symptoms of low blood sugar or readings far outside your range, contact your care team right away.
