When Should You Check Your Blood Sugar?

Check your blood sugar levels - it's a non-negotiable part of having diabetes. It provides important information around what’s going on inside of your body so that you can properly address it as needed. One of the most important pieces of testing your glucose levels is deciding what times of the day are best to do so.

Why blood sugar testing matters

Blood sugar levels change throughout the day. When you have diabetes, fluxes in your glucose levels can require interventions to keep it within a healthy range. These numbers are influenced most by what you eat or drink, but can also be affected if you’ve been physically active, haven’t slept well, or are under stress. Regularly testing your blood sugar provides insight into when and how much these levels are influenced. It also helps you determine whether an intervention is needed, such as having a snack to bring levels up or taking insulin to bring them down. Keeping a record of your blood sugar levels throughout the day can indicate trends in your body. This is helpful when you’re designing a diabetes self-management plan or when you want to make changes to your current routine. For instance, the best time to check blood sugar for type 2 diabetes may differ from type 1 diabetes, depending on the person.

How often to test

How often you test your blood sugar is ultimately up to you to decide. However, getting into a routine of testing your glucose level several times per day will be the most helpful for your diabetes management plan. In the beginning, newly diagnosed individuals will likely be testing more frequently to get a better idea of what your blood sugar is doing. You start by establishing a baseline. From there, you’ll develop a routine of testing your levels and knowing when they may be too high or too low.

Best time to check blood sugar

Good diabetes management includes monitoring your blood glucose levels regularly throughout each day, but exactly when should you check your blood sugar for the best information? Several times are recommended for the most control.

If you use insulin injections, wear an insulin pump, or use other medications for diabetes control, it’s also likely recommended to check your blood sugar several times per day. If you have any questions about how often or when to check blood sugar levels, be sure to speak with your healthcare team for personalized directions. The best time to check blood sugar depends on your personal diabetes experience, blood sugar trends, and whether you have high or low blood sugar symptoms. Overall, it’s a good practice to check your levels multiple times throughout the day and around the same times. When you wake up, before and after meals, around physical activity, and before bedtime are some of the key times to gather the data you need for optimal blood sugar control.
