Prediabetes is a growing public health concern because millions of people may have elevated blood sugar without realizing it.
The condition occurs when blood glucose levels are higher than normal but have not reached the threshold for type 2 diabetes.
Early identification offers an important opportunity to reduce the risk of developing diabetes and its associated complications.
Why Prediabetes Often Goes Undetected
Prediabetes frequently develops without noticeable symptoms. Individuals may feel completely healthy while their blood sugar levels gradually increase.
Risk factors include excess body weight, family history of diabetes, physical inactivity, and increasing age.
According to the Centers for Disease Control and Prevention (CDC), blood tests are necessary to identify prediabetes reliably.
Understanding the HbA1c Test
One of the most commonly used screening methods is the HbA1c test, which measures average blood sugar levels over approximately two to three months.
An HbA1c result between 5.7% and 6.4% indicates prediabetes, while a result of 6.5% or higher falls within the diabetes range. Diagnosis may require confirmation with additional testing.
A fasting blood glucose test is another common diagnostic option.
Can Prediabetes Be Reversed?
Many individuals can return their blood sugar levels to the normal range through sustained changes in physical activity, nutrition, and weight management.
However, people with significant risk factors may require additional medical evaluation and, in selected cases, preventive medication.

When Should You Get Tested?
Adults with obesity, a family history of diabetes, high blood pressure, or other metabolic risk factors should discuss diabetes screening with their doctors.
Screening may also be appropriate for people without symptoms, depending on their age and medical history.

The Bottom Line
Prediabetes is an important early warning sign. Timely screening and medical intervention can help prevent or delay progression to type 2 diabetes.
