If your doctor has mentioned that your blood sugar is "a little high," you are far from alone. According to the CDC, more than 2 in 5 American adults have prediabetes, and many don't know it, because it usually causes no symptoms.
The good news is that prediabetes is a signal, not a sentence. Here is what it means and what research says helps.
What prediabetes is
Prediabetes means blood sugar levels are higher than normal but not high enough to be diagnosed as type 2 diabetes. It raises the risk of type 2 diabetes, heart disease and stroke over time. The body is still producing insulin, but it is not moving glucose out of the blood as efficiently as it used to.
What the numbers mean
Doctors usually use one of these tests. The ranges below are the standard ones used in the US:
| Test | Normal | Prediabetes | Diabetes |
|---|---|---|---|
| A1C (average over ~3 months) | Below 5.7% | 5.7–6.4% | 6.5% or higher |
| Fasting blood glucose | Below 100 mg/dL | 100–125 mg/dL | 126 mg/dL or higher |
| 2-hour glucose tolerance test | Below 140 mg/dL | 140–199 mg/dL | 200 mg/dL or higher |
Only your doctor can diagnose prediabetes or diabetes, and usually confirms results with repeat testing.
Who should get tested
Ask your doctor about testing if you are 45 or older, have a family history of type 2 diabetes, carry extra weight, are not very active, or had diabetes during pregnancy. Many people learn they have prediabetes only because of a routine blood test.
What helps, according to the CDC
The CDC highlights two changes that make a real difference:
- Modest weight loss: losing about 5% to 7% of body weight, around 10 to 14 pounds for a 200-pound person.
- Regular activity: at least 150 minutes a week of brisk walking or similar activity, about 30 minutes a day, 5 days a week.
The CDC also recognizes structured lifestyle change programs (the National Diabetes Prevention Program) that help people make these changes with support.
Small daily habits that add up
Big goals are easier when they are broken into daily routines. At DVY Herbal, we focus on four:
- Plate: half your plate non-starchy vegetables (how it works).
- Order: vegetables and protein before carbs (why).
- Move: a short walk after lunch and dinner (the research).
- Rhythm: regular meal times and 7–8 hours of sleep.
These habits don't replace medical care. They work best alongside regular checkups and the plan you build with your doctor.
