Using Glucometers and CGMs, Chapter 1: Why Checking Blood Sugar Matters
Why Your Targets Matter
Your good blood sugar number depends on your own goal, set with your doctor.
Understand that a good number depends on the goal you set with your doctor.
A target is the range your doctor sets with you. It is your own goal, not a score you pass or fail.
Fasting readings are taken after a long break from food. People with diabetes often aim for 80 to 130 mg/dL (4.4 to 7.2 mmol/L).
That range is a common example, not a rule. Your own goal may be higher or lower.
Some people need a different goal. Older adults and people with other serious conditions may have a looser goal. A looser goal means a wider range.
Looser goals may help lower the risk of dangerous lows. A low is when blood sugar drops too far down.
Pregnancy targets are tighter, meaning a narrower range, than targets for most adults. Some medicines can also change your goal.
A reading outside your target is a reason to pay attention, not to panic.
One reading only shows one moment. Write down the time and what you ate. Keep those notes over several days.
Patterns over days tell you more than one number does. Ask your care team which times to check. Bring your notes and questions to your next visit.
Key takeaways
- Your target is your own goal, set with your doctor.
- 80 to 130 mg/dL (4.4 to 7.2 mmol/L) is a common example for people with diabetes, not a rule.
- An outside reading is a signal to note the time and meal, then bring it up.
