Question: How often should I check my blood glucose?
|Type of Diabetes||When to Check Blood Glucose|
|Type 1 diabetes||Check before each meal and at bedtime (at least four times a day).|
|Type 2 diabetes and taking insulin||Check between two and four times a day; times will vary depending on your insulin regimen.|
|Type 2 diabetes and taking diabetes pills||Check one or two times a day. If you check once, do so before you eat breakfast. If you check twice a day, check in the morning, and vary the time of the second check.|
|Type 2 diabetes with no medication||Check before breakfast and two hours after a meal, alternating the mealtime; you may not need to check every day if your A1C is below 7 percent.|
Occasionally checking blood glucose two to three hours after finishing a meal is helpful for people with either type 1 or type 2 diabetes. It also is a good idea to check your blood glucose more often than usual in the following situations:
- If you're changing your meal plan
- If you're changing your diabetes pills or insulin dose
- When you think your blood glucose is low
- When you are sick
- If you are pregnant
- Before and after physical activity
- Before driving
No matter how often you check, keep a record of your blood glucose readings, and always bring the record to your diabetes appointments. This way, you can discuss your numbers with your healthcare provider or diabetes educator, and they can answer any questions you may have regarding your results. Also, having your numbers in a logbook can help your healthcare team decide if any changes may be needed in your diabetes treatment plan.
