How To Check Your Blood Sugar
WHAT YOU NEED TO KNOW:
Your healthcare provider will tell you when and how often to check your blood sugar levels during the day. Your provider may use the results to make changes to your medicine, food, or exercise schedules.
Have someone call 911 for any of the following:
- You cannot be woken.
- You have chest pain or shortness of breath.
Return to the emergency department if:
- You have a low blood sugar level and it does not improve with treatment.
- Your blood sugar level is above 240 mg/dL and does not come down after you take a dose of insulin.
- You have ketones in your blood or urine.
- You have blurred or double vision.
- Your breath has a fruity, sweet smell, or your breathing is shallow.
- You have symptoms of a low blood sugar level, such as trouble thinking, sweating, or a pounding heartbeat.
Contact your healthcare provider if:
- Your blood sugar levels are higher than your target goals.
- You often have low blood sugar levels.
- You have trouble coping with your illness or you feel anxious or depressed.
- You have questions or concerns about your condition or care.
How to check your blood sugar:
You will be taught how to check a small drop of blood with a glucose meter. Get all of your supplies together, such as your meter, test strips, and lancet device. Be sure to read the information that came with your meter. Use the following steps as a guide:
- Wash your hands. Use warm water to help blood flow. Dry your hands completely.
- Put the test strip in the meter. This will turn on your meter.
- Use the lancing device to stick your finger or area. Do not use the same finger or area every time. Stick the side of your fingertip, not the middle. The side may cause less pain.
- Squeeze your fingertip or area gently.
- Touch the drop of blood to the test strip. A number will appear on the meter after a few seconds. This is your blood sugar level.
When to check your blood sugar level:
- If you check your blood sugar level before a meal , it will show your lowest blood sugar. If you check your blood sugar level 2 hours after a meal , it will show your highest blood sugar. Ask your healthcare provider what good goals are for your blood sugar levels at different times.
- You may need to check for ketones in your urine or blood if your blood sugar level is higher than directed.
Follow up with your healthcare provider as directed:
Write down your results and show them to your healthcare provider at every visit. Also, write down your questions so you remember to ask them during your visits.
