These studies suggest that pre-diabetes is a condition with varying global prevalence and associated risks, which can be managed through lifestyle changes and monitored by blood glucose levels, but there is debate regarding its diagnosis and the optimal targets for glycemic control.

Understanding the Pre-Diabetic Glucose Range
Definition and Diagnostic Criteria of Pre-Diabetes
Pre-diabetes is a condition where blood glucose levels are elevated above normal but not high enough to be classified as diabetes. This state is a critical indicator of increased risk for developing type 2 diabetes and associated complications . The diagnosis of pre-diabetes can be made using several tests, including fasting plasma glucose (FPG), oral glucose tolerance test (OGTT), and glycated hemoglobin (HbA1c).
Fasting Plasma Glucose (FPG)
The American Diabetes Association (ADA) defines impaired fasting glucose (IFG) as a fasting glucose level between 100 and 125 mg/dL (5.6 to 6.9 mmol/L) . This range has been adjusted over time to improve sensitivity in identifying individuals at risk of progressing to diabetes.
Oral Glucose Tolerance Test (OGTT)
Impaired glucose tolerance (IGT) is identified through the OGTT, where a 2-hour plasma glucose level between 140 and 199 mg/dL (7.8 to 11.0 mmol/L) indicates pre-diabetes . This test is less commonly used due to its complexity but remains a valuable diagnostic tool.
Glycated Hemoglobin (HbA1c)
An HbA1c level between 5.7% and 6.4% (39 to 47 mmol/mol) is also used to diagnose pre-diabetes . This test reflects average blood glucose levels over the past two to three months and is convenient for both patients and healthcare providers.
Prevalence and Risk Factors
Pre-diabetes is highly prevalent, particularly among older adults and individuals with obesity . The condition is often associated with metabolic syndrome, which includes risk factors such as hypertension, dyslipidemia, and central obesity. Ethnic differences also play a role, with variations in the prevalence of IFG and IGT observed between different populations.
Implications and Management
Identifying pre-diabetes is crucial for preventing the progression to type 2 diabetes and reducing the risk of cardiovascular diseases . Lifestyle interventions, including dietary changes, increased physical activity, and weight loss, are the primary strategies for managing pre-diabetes . Pharmacotherapy may also be considered in some cases to delay the onset of diabetes.
Conclusion
Pre-diabetes is a significant health concern that serves as a warning sign for the potential development of type 2 diabetes. Understanding the diagnostic criteria and implementing effective management strategies can help mitigate the risks associated with this condition. Regular screening and early intervention are essential to prevent the progression to diabetes and improve overall health outcomes.
