If you've been diagnosed with type 2 diabetes, the target range your doctor gives you probably looks a little different from the "normal" ranges you'll find in a general reference chart — and that's intentional, not a mistake. Here's why, and what the commonly used targets actually are.
The commonly cited ADA target range
For most non-pregnant adults with diabetes, the American Diabetes Association's commonly cited general targets are:
- Before meals (preprandial): 80–130 mg/dL (4.4–7.2 mmol/L)
- 1–2 hours after the start of a meal (postprandial): under 180 mg/dL (under 10.0 mmol/L)
- A1C: generally under 7%, though this is individualized
Notice that the before-meal target (80–130 mg/dL) is slightly wider than the "normal" fasting range covered in our complete healthy blood sugar levels guide (under 100 mg/dL). That gap is deliberate.
Why the target is different from "normal"
These targets aren't trying to force blood sugar back down to non-diabetic levels — they're built around a trade-off. Pushing glucose too aggressively toward "normal" non-diabetic numbers raises the risk of hypoglycemia (blood sugar dropping too low), which carries its own serious short-term risks. The ADA's ranges are designed to meaningfully reduce long-term complication risk while keeping day-to-day hypoglycemia risk low and manageable.
Why your personal target might look different
The ranges above are general starting points, not universal prescriptions. Your doctor may set a different target based on:
- Age: older adults are often given a somewhat higher, safer target — see Healthy Blood Sugar Levels by Age.
- How long you've had diabetes and how it's currently managed (lifestyle, oral medication, or insulin).
- Other health conditions, such as heart, kidney, or lung disease.
- Hypoglycemia awareness — some people don't feel the early symptoms of low blood sugar and are given a higher safety margin as a result.
- Pregnancy, which uses its own distinct targets entirely — see Healthy Blood Sugar Levels for Women.
Staying within your target range
The day-to-day levers for staying within range are the same fundamentals covered in How to Maintain Healthy Blood Sugar Levels: consistent meal patterns, carbohydrate quality, regular activity (especially post-meal movement), sleep, and stress management — on top of whatever medication your doctor has prescribed. Regular self-monitoring and periodic A1C checks are how you and your care team track whether your current plan is working.
A daily complement to your routine
Some people managing type 2 diabetes add a formulated daily supplement alongside their doctor-directed plan. See the GlycoBalance formula — chromium plus a botanical and amino acid blend — and always discuss any new supplement with your doctor first, especially if you take diabetes medication.
The takeaway
The commonly cited target range for type 2 diabetes (roughly 80–130 mg/dL before meals, under 180 mg/dL after meals, A1C generally under 7%) is intentionally wider than "normal" non-diabetic ranges, to balance long-term control against the real risk of blood sugar dropping too low. Your own target should always come from your doctor, not a general chart.
