What is Prediabetes?

Prediabetes is a condition in which blood glucose or A1C levels—which reflect average blood glucose levels—are higher than normal but not high enough for a diagnosis of diabetes. It is becoming more common in the United States. The Center for Disease Control estimated that in the US, 88 million adults – 1 in 3 people – had prediabetes 2018. A 2012 study projected that more than 470 million people worldwide will have it by 2030. People with prediabetes are at increased risk of developing Type 2 diabetes and cardiovascular disease, which can lead to a heart attack or stroke.

Tests for Prediabetes and Its Ranges:

Prediabetes can be determined using your A1C, measuring your fasting blood sugar, or through an oral glucose tolerance test. Each test uses a specific range to determine it.

A1C: Measures your average blood sugar over the previous 3 months.

  • Prediabetes range: 5.7 to 6.4 percent

Fasting Blood Sugar: Your blood sugar sample after fasting overnight or after at least 8 hours.

  • Prediabetes range: 5.5 to 6.9 mmol/L100 to 125 mg/dL

Oral Glucose Tolerance Test: A used to diagnose gestational diabetes and Type 2 diabetes. You drink a sweet drink and then your blood sugar is tested 2 hours later.

  • Prediabetes range: 7.8 mmol/L140 mg/dL to 11.1 mmol/L199 mg/dL
