When you have diabetes, you need to check your blood sugar throughout the day. It can help you decide what to eat, if you need to adjust your medication, and help you steer clear of complications like:
Ways to Check Your Blood Sugar
Self-Checking: Give yourself a blood sugar test several times a day. To do it, you use a gadget that pricks your finger with a tiny needle. You’ll put a drop of blood onto a test strip. The strip goes into a handheld device that measures your blood sugar level.
Write down the test results, so you can share it with your doctor. Based on your results, the two of you may adjust your diet, exercise, or medication.
A1c Test: This is a blood test you'll get in your doctor's office at least twice a year, or as often as he recommends.
The results show your average blood sugar control for the past 2 to 3 months. You and your doctor need this test to see how well your diabetes treatment plan is working, so you can make changes if you need to.
Think of it this way: Self-checking is like a daily snapshot of your blood sugar control. The A1c test gives you the big picture.
Continuous Glucose Monitoring System: Some people opt forthis.If you get one, your doctor will place a tiny sensor under your skin to check blood sugar levels every 5 minutes. It sends data to a monitor that you wear like a pager for a few days.
You'll still need to check your levels throughout the day; continuous glucose monitoring doesn't replace that. It gives your doctor more information about trends that self-checking might not show.
