A Novel Approach to Mitigating the Systemic Health Impacts of Postprandial Hyperglycemia

Abstract

Introduction: Postprandial hyperglycemia (PPHG) is a common metabolic disorder in both type 1 and type 2 diabetes and plays a significant role in the development of microvascular and macrovascular complications. Elevated blood glucose levels after meals, through mechanisms such as oxidative stress, inflammation, and pancreatic beta-cell dysfunction, can lead to vascular damage and progression of chronic diabetic complications.

Materials and Methods: This study was conducted as a narrative review. Scientific literature was searched in PubMed, Scopus, Web of Science, and Google Scholar databases. Studies related to non-pharmacological and pharmacological interventions effective in controlling postprandial hyperglycemia including post-meal physical activity, consumption of fiber or vegetables before meals, vinegar intake, low glycemic index diets, insulin therapy, and GLP-1 receptor agonists were reviewed and qualitatively analyzed.

Results: The reviewed studies indicated that inadequate control of PPHG is associated with an increased risk of microvascular complications such as retinopathy, nephropathy, and neuropathy, as well as macrovascular complications including cardiovascular diseases. Lifestyle interventions, particularly low–glycemic index diets and regular physical activity, play an effective role in reducing postprandial blood glucose levels. However, pharmacological treatments alone are not sufficient to achieve complete control of PPHG in all patients.

Conclusion: Effective control of postprandial hyperglycemia requires a multifaceted approach that includes dietary modification, increased physical activity, appropriate pharmacological therapy, and careful blood glucose monitoring. Given the limited long-term evidence, future studies are needed to evaluate the sustained effectiveness of these interventions and to explore the use of novel continuous glucose monitoring technologies.
