Understanding Prediabetes
It signals an increased risk of developing type 2 diabetes and often occurs with insulin resistance. Many people have no symptoms. Blood testing, rather than symptoms alone, identifies the condition.
How it is assessed or used in care
Clinicians may use A1c, fasting glucose, or an oral glucose tolerance test. A finding of prediabetes is an opportunity to discuss activity, nutrition, weight-related goals when appropriate, and follow-up testing. Medication may be considered for some people.
What to discuss with your clinician
Ask which test identified the problem and when it should be repeated. Prediabetes does not mean progression to diabetes is inevitable, but it does deserve follow-up. Seek a personalized plan rather than relying on an extreme diet or unproven treatment.
