Monitoring Your Blood Sugar

The only way to be sure your blood sugar stays within a normal range is to check it. You will most likely be asked to check your blood sugar at home one or more times a day. Your healthcare provider will teach you how. He or she may also ask you to check your urine at home. Your blood sugar may also be checked every week or so in the lab.

Your healthcare provider will discuss the best way and times for you to check your blood sugar, and show you what to do. Your blood sugar is usually highest about an hour after you eat. You can check it using a meter.

  • Be sure to read the instructions that come with your meter. Follow them carefully.

  • Record your blood sugar level every time you check it. Bring your records and your meter to all your appointments with your healthcare provider.

  • If your blood sugar is unusually low or high, check it again in 20 to 40 minutes.

If You Check Your Urine at Home

If you don't eat enough, your body will burn fat to get energy. This leaves ketones in your urine. Your healthcare provider may have you check your urine for ketones each morning. You'll use special strips that change color if there are ketones. If you have ketones, this may mean that you're not getting enough calories. Your healthcare provider may make changes in your meal plan.
