A blood sugar range chart is a way to watch your blood sugar levels and take care of your diabetes. Different charts may have different goals for different times of the day, depending on how old you are, how healthy you are, and what kind of diabetes you have. Here is a short explanation of some common blood sugar range charts in about 400 words:
- Normal goals for adults with type 1 and type 2 diabetes and kids with type 2 diabetes³:
- Fasting (before eating): 80–130 mg/dL
- 1–2 hours after eating: Lower than 180 mg/dL
- A1C levels for people who don’t have diabetes, who have prediabetes, and who have diabetes³:
- A person who doesn’t have diabetes: Below 5.7%
- A person who has prediabetes: 5.7–6.4%
- A person who has diabetes: 6.5% or higher
- Blood sugar levels for children under 18 years with type 1 diabetes⁴:
- Fasting (before eating): 90–130 mg/dL
- Bedtime and overnight: 90–150 mg/dL
- Blood sugar levels for pregnant people with type 1 diabetes⁴:
- Fasting (before eating): Lower than 95 mg/dL
- 1 hour after eating: 140 mg/dL or lower
- 2 hours after eating: 120 mg/dL or lower
- Blood sugar levels for people with gestational diabetes⁴:
- Fasting (before eating): Lower than 95 mg/dL
- 1 hour after eating: 140 mg/dL or lower
- 2 hours after eating: 120 mg/dL or lower
- Blood sugar levels for people who don’t have diabetes⁴:
- Fasting (before eating): 72–99 mg/dL
- 2 hours after eating: Less than 140 mg/dL
These are general rules and your personal goals may be different depending on what your doctor says. You can use a glucose meter or a continuous glucose monitor to check your blood sugar levels and see how they match the chart. You can also use a blood sugar log to write down your readings and see how you are doing over time. Keeping your blood sugar levels in the suggested range can help you avoid or delay diabetes problems and make your life better.
