Prediabetes Diagnosis: Criteria and Screening Keywords
Prediabetes is an intermediate state where blood glucose levels are higher than normal but not high enough for a diabetes diagnosis. The most widely used diagnostic criteria include a fasting plasma glucose (FPG) level of 100–125 mg/dL, a 2-hour glucose level of 140–199 mg/dL after a 75-gram oral glucose tolerance test, or a glycated hemoglobin (HbA1c) of 5.7%–6.4% Echouffo-Tcheugui2023Bansal2015Andari2021. However, there is some variation in these thresholds among different international organizations Bansal2015Andari2021. Screening is generally recommended for adults over 45 years old or younger adults with risk factors such as obesity, family history, or other metabolic conditions Andari2021Bell2020.
Prediabetes Risk and Associated Complications Keywords
Prediabetes is not a benign condition. It is associated with a higher risk of developing type 2 diabetes, with about 5–10% of individuals progressing to diabetes each year Echouffo-Tcheugui2023Bansal2015Echouffo-Tcheugui2023. Additionally, prediabetes increases the risk of cardiovascular events, mortality, and early complications such as nephropathy, neuropathy, and retinopathy Echouffo-Tcheugui2023Bansal2015.
Management of Prediabetes: Lifestyle Modification and Pharmacotherapy Keywords
The first-line management for prediabetes is intensive lifestyle modification. This includes calorie restriction, increased physical activity (at least 150 minutes per week), weight loss (aiming for 5–10% of body weight), self-monitoring, and motivational support Echouffo-Tcheugui2023Bansal2015Bell2020. Lifestyle interventions can reduce the risk of developing diabetes by 40–70% Echouffo-Tcheugui2023Bansal2015Bell2020.
Pharmacotherapy, particularly metformin, is considered for high-risk individuals, such as those with a BMI ≥35, women with a history of gestational diabetes, or those with higher baseline glucose or HbA1c levels Echouffo-Tcheugui2023Bansal2015Dora2024. Metformin reduces diabetes risk, but other medications are less commonly used due to potential side effects Bansal2015Dora2024. In rare cases, bariatric surgery may be considered for individuals with severe obesity Andari2021Bell2020.
Challenges in Prediabetes Recognition and Management in Clinical Practice Keywords
Despite clear evidence supporting early intervention, prediabetes is often underdiagnosed and undertreated in primary care settings Mainous2016Njeru2019. Many patients with laboratory evidence of prediabetes do not receive a formal diagnosis or management recommendations, highlighting missed opportunities for diabetes prevention Mainous2016Njeru2019. Recognition is more likely in individuals with higher BMI, while those with normal BMI are less likely to be identified .
Advances in Precision Diagnosis: Biomarkers and Technology Keywords
Emerging multi-omics approaches and non-invasive technologies are enhancing the precision of prediabetes diagnosis. Multi-omics (genomics, metabolomics, proteomics, etc.) can identify new biomarkers and provide personalized risk assessments, although challenges remain in data integration and clinical application . Additionally, portable biochips and smartphone-based sensors now allow for real-time, non-invasive monitoring of glucose and insulin, offering promise for early and precise diagnosis at the point of care .
Conclusion
Prediabetes is a common and serious health condition that increases the risk of diabetes and cardiovascular disease. Diagnosis relies on blood glucose and HbA1c thresholds, but recognition in clinical practice remains suboptimal. Intensive lifestyle modification is the cornerstone of management, with metformin reserved for high-risk cases. Advances in biomarker discovery and non-invasive monitoring may further improve early detection and personalized management in the future.
