Checking your blood glucose levels is an important part of managing diabetes. Knowing your levels tells you how well your care plan is working and if any changes should be made. Read on to learn more!
Who Should Check
Anyone with diabetes can benefit from checking blood glucose, especially if you:
- Take insulin or pills for diabetes.
- Have a hard time controlling blood glucose.
- Have severe low blood glucose levels or ketones from high blood glucose levels.
- Have low blood glucose without the usual warning signs.
When to Check
Your health care provider will tell you when to check your blood glucose. Here is a general guideline:
- Before eating breakfast, lunch, and dinner (or a really big snack).
- 1 to 2 hours after eating breakfast, lunch, and dinner (or a really big snack).
- Before going to bed for the night.
- At 2 or 3 a.m. (if you happen to be awake).
How to Check
To check your blood glucose, you stick your finger with a special needle, called a lancet. This will give you a drop of blood to put on a test strip. The test strip goes into a blood glucose meter, which is a small machine that "reads" your blood glucose.1. Wash your hands with soap and water.
2. Stick your fingertip with a lancet (use the side of your finger near your fingernail).
3. Squeeze your finger until you get a drop of blood. Put the blood on the test strip. (If you have trouble getting blood, wash your finger with warm water, hold your hand down, or squeeze your finger.)
4. Put the strip into the meter and follow the meter's instructions.
Note: Some meters let you test other areas, such as your upper arm, forearm, base of thumb, or thigh. But it's best to use your fingertip when you suspect low blood sugar.
Keeping Track
Keep a log of your blood glucose levels. This will help you see how food, activity, and stress can affect your levels. If they are often too high or too low, your health care provider may need to change your diabetes plan. Bring your log with you when you see your health care provider. Use this example, or ask your diabetes health care team for a log.
