Checking Blood Sugars

Did you know that checking your blood sugar regularly can help lower your HbA1c? By checking your blood sugars more often, you will be able to respond to out-of-range blood sugars more quickly or confirm that you’re still in range. Checking your blood sugars consistently will also allow you to see blood sugar patterns and trends that will help you make decisions about your behaviors and insulin dosing.


We recommend that patients check their blood sugar between 4 - 8 times per day or use a continuous glucose monitor (CGM).

Talk to your care team about using a CGM.

Set up a reward system for checking, like picking the family movie or board game.

Use sticky notes in common areas as reminders to check.

Set alarms before meals to remind you to check. Try using different songs for each time of the day.

Use a log, journal, or chart to help keep track of your numbers. Logging apps work great for this!

Turn checking into a game! Try making a Blood Sugar Bingo card or guessing the number before you see it. 

Bolus Insulin Delivery

Insulin delivery is a vital part of managing T1D and lowering HbA1c. It’s important to give a bolus with every meal to cover the carbs and keep your blood sugar in check. You may also need to respond to high blood sugars between meals by giving insulin in the form of correction doses. By keeping up with these behaviors, you can keep your blood sugar in check and lower your A1c over time.

Talk to your care team about using an insulin pump.

Keep your insulin supplies where you use them most so you don’t have to worry about finding them.

Ask teachers to leave class early enough to give insulin. Use the bathroom or the school office for privacy.

Set alarms before meals to remind you to give insulin 10-15 minutes before eating.

Remember to rotate your injection spots for comfort and effectiveness.

Don’t forget to celebrate your successes! Be proud of your successful days.

Reviewing Diabetes Data

Type 1 diabetes is an ever-changing condition. It’s important to know whether your behaviors and insulin regimen need to be changed to better manage T1D. Your diabetes care team will review your blood sugar logs and recommend changes to your care routine at each clinic visit, but you should make time to review this information between visits to stay as healthy as possible.

Be sure to keep accurate blood sugar logs with carb information and insulin doses to review later.

Check your blood sugar logs for patterns, like high blood sugars after meals or low blood sugars after boluses.

Ask about a refresher diabetes education class if you need help reading your blood sugar logs.

Set a weekly or bi-weekly reminder to review your blood sugar logs.

Talk to your care team if you need help making adjustments to your insulin regimen.

Remember to wait a few days between any changes to your diabetes routine to ensure they’ve worked.
