Prediabetes

Diabetes is a treatable disease, especially if detected early. Early detection and treatment can greatly lower the likelihood of subsequent problems. Prediabetes nearly often develops before type 2 diabetes. Your blood sugar levels are high in the prediabetes stage, but not high enough to earn a diabetes diagnosis. You may or may not have diabetic symptoms if you have prediabetes.

If you suspect or know you have prediabetes, the three primary types of diabetes testing will reveal the following blood levels:

• an A1C of 5.7 to 6.4 percent
• fasting blood sugar of 100–125 milligrams per deciliter (mg/dl)
• an OGTT 2-hour blood sugar of 140 mg/dl–199 mg/dl
