Reading Your Numbers

A blood sugar target is a range many people aim for. The American Diabetes Association (ADA) suggests ranges for many adults. They do not fit everyone.

Before a meal, the ADA suggests 80 to 130 mg/dL (4.4 to 7.2 mmol/L). After a meal, it is under 180 mg/dL (under 10.0 mmol/L). That is checked 1 to 2 hours after the meal starts.

A handheld glucometer, with a test strip and a drop of blood at the top, sits next to a range bar with Low, In range and High zones for before a meal. Low is under 70 mg/dL (3.9 mmol/L), and the screen reads 62 mg/dL, 3.4 mmol/L. In range is 80 to 130 mg/dL (4.4 to 7.2 mmol/L), and the screen reads 105 mg/dL, 5.8 mmol/L. High is above 130 mg/dL (7.2 mmol/L), and the screen reads 180 mg/dL, 10.0 mmol/L. The marker slides to the matching zone as the screen number changes, and that zone lights up.

A low, called hypoglycemia, is under 70 mg/dL (under 3.9 mmol/L). Lows can hit without warning. It helps to know your plan ahead of time.

Ask your team what your low plan should be. Call emergency services if you feel confused or cannot treat it.

Three steps: know what a low is, ask your team for your low plan, and call emergency services if you feel confused or faint.

Key takeaways

• Before meals, the ADA suggests 80 to 130 mg/dL (4.4 to 7.2 mmol/L) for many adults.
• After a meal, the suggested goal is under 180 mg/dL (under 10.0 mmol/L).
• Under 70 mg/dL (under 3.9 mmol/L) is a low, and your doctor sets your own targets.

Try it

Look at your meter's settings or manual to see whether it shows mg/dL, mmol/L, or both. Then write one question about your own range for your next visit.
