You’ve received plenty of good advice already. Be aware that our fingerstick meters use one of two numbering systems. It depends on what country you are located. In the US our blood sugar numbers are denominated in “milligrams per deciliter” of blood, abbreviated as mg/dL. Generally speaking, under 70 mg/dL is low, 70-140 mg/dL is normal, and above 140 mg/dL is thought to be high. These ranges are not carved in stone somewhere and your personal low, normal, and high ranges may vary some.
Countries like Canada and the UK use a glucose measuring system based on “millimoles per liter” or abbreviated to mmol/L. The low range is often thought to be below 4.0 mmol/L. The normal range is generally thought to be from 4.0-8.0 mmol/L, while numbers above 8.0 mmol/L are often considered high.
To convert mmol/L to mg/dL just multiply by 18. To convert mg/dL to mmol/L, divide by 18. Your personal low, normal, and high ranges may start and stop at different numbers. Also, your doctor may provide a wider range for you to target. This can help to not discourage you, especially in the beginning.
Try not to compare your numbers to others who you read about here. We try not to be competitive and when you think about it, your only competition is with yourself. Also, realize that a number is neither good nor bad. This is important to let sink in! It is simply information, like a sign-post, helping to indicate what you should do next. The numbers you view is not an evaluation to determine that you, as a person and/or diabetic, are good or bad. See these numbers as information only, not your self-worth. In diabetes, information can create power. Good luck!
