Checking Blood Glucose

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


We recommend that patients check their blood glucose 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 Glucose 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 glucose in check. You may also need to respond to high blood glucose between meals by giving insulin in the form of correction doses. By keeping up with these behaviors, you can help keep your blood glucose in range and lower your HbA1c over time.

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

T1D is an ever-changing condition, and it’s important to know whether your behaviors and/or insulin doses need to be changed. Your diabetes care team will review your blood glucose logs or CGM/pump data and recommend changes to your care routine at each clinic visit, but we recommend you make time to review this information and make adjustments between visits to better manage your diabetes.

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


Check your blood glucose logs for patterns like high blood glucose after meals or low blood glucose after boluses.


Ask about a refresher diabetes education class if you need help reading your blood glucose logs or CGM/pump data.


Set a weekly or bi-weekly reminder to review your blood glucose logs or CGM/pump data.


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.
