Prediabetes and Type 2 Diabetes: Screening and What Primary Care Can Do

What is the difference between prediabetes and type 2 diabetes?

Both conditions are measured with the same blood tests, most commonly the hemoglobin A1C, which reflects your average blood sugar over the past two to three months. The American Diabetes Association defines the ranges as:

• Normal: A1C below 5.7 percent.
• Prediabetes: A1C of 5.7 to 6.4 percent.
• Diabetes: A1C of 6.5 percent or higher, confirmed on a second test.

Who should be screened for diabetes?

The USPSTF recommends screening for prediabetes and type 2 diabetes in asymptomatic adults ages 35 to 70 who have overweight or obesity, and the American Diabetes Association recommends testing at any age for adults with risk factors such as a family history of diabetes, a history of gestational diabetes, polycystic ovary syndrome, or membership in a higher-risk racial or ethnic group. Screening may be done with a fasting blood glucose, an A1C, or an oral glucose tolerance test.

What can primary care do for prediabetes?

Prediabetes is a warning sign, and it is also an opportunity: for many people, structured lifestyle change and weight management can return blood sugar to a normal range. Effective interventions include a modest, sustained weight loss, increased physical activity, and healthier eating patterns. Some people with prediabetes may also be candidates for medication, and your provider can discuss whether that fits your situation.

How is type 2 diabetes managed in primary care?

Type 2 diabetes is a chronic condition that is managed, not cured, and good management prevents complications. Care typically includes individualized blood sugar targets, medication when needed, blood pressure and cholesterol control, foot and eye checks, kidney monitoring, and annual exams. The goal is a plan you can actually live with, adjusted at follow-up visits as your numbers and needs change.

When should you talk with a provider?

Talk with a provider if you have never been screened and you are 35 or older with overweight or obesity, if you have risk factors for diabetes, or if you notice symptoms such as increased thirst, frequent urination, unusual fatigue, or blurry vision. Screening is also a routine part of annual wellness visits, so if you are due for a checkup, that is a natural time to ask.
