The prevalence of the obesity epidemic, triggered by the increase in caloric content of meals and insufficient physical activity, leads to a growing number of pre-diabetic diagnoses (including children and adolescents). In view of the present knowledge, the incidence of prediabetes is invariably associated with an increased risk of developing manifest diabetes in the near future...
Prediabetic metabolic syndrome: Impaired glycemic regulation in the preclinical phase
Within clinical endocrinology, the terms *impaired fasting glucose* (IFG) and *impaired glucose tolerance* (IGT) are collectively categorized under the umbrella of *prediabetic state*—commonly referred to as prediabetes. This classification is applied when fasting plasma glucose levels exceed the established physiological range (70–99 mg/dL, as defined by the American Diabetes Association and Polish Diabetes Association), registering between 100–125 mg/dL, and/or when the 120-minute oral glucose tolerance test (OGTT) reveals venous plasma glucose concentrations of 140–199 mg/dL, signaling the onset of dysregulated carbohydrate metabolism.
Early-stage markers of impaired glucose tolerance: Identifying prediabetes before progression to overt type 2 diabetes
Disorders of carbohydrate metabolism progress insidiously, with detection frequently delayed by months or even years due to the subtle nature of early pathophysiological alterations [1]. A primary challenge in identifying prediabetes lies in the absence of distinct, readily observable clinical manifestations—particularly in the initial phases of metabolic dysregulation—despite the fact that even modest elevations in blood glucose levels exert deleterious effects on vascular endothelial integrity and peripheral nerve fibers [1]. Nevertheless, a constellation of risk factors has been established that significantly elevates susceptibility to both prediabetic states and overt type 2 diabetes. Among the most critical are: excess body weight (BMI ≥ 25 kg/m²), sustained arterial hypertension (≥140/90 mmHg), physical inactivity, a first-degree family history of diabetes, dyslipidemia characterized by reduced high-density lipoprotein (HDL) cholesterol alongside elevated triglyceride concentrations, and tobacco smoking. Given the frequently asymptomatic presentation during early stages, individuals at heightened risk are strongly advised to undergo periodic screening assessments—including fasting plasma glucose (FPG) measurements and oral glucose tolerance testing (OGTT)—to detect impaired fasting glucose (IFG) or impaired glucose tolerance (IGT). The identification of these conditions represents a pivotal opportunity to implement timely therapeutic interventions and lifestyle modifications aimed at halting progression to frank diabetes and mitigating the onset of microvascular and macrovascular complications.
Pre-diabetic condition diet
The main objective of the treatment of patients with pre-diabetes mellitus is to reduce the risk of developing type 2 diabetes mellitus and to reduce their risk of heart-and-cardiovascular complications.[2] The diet of people with impaired glucose tolerance should be balanced against the need for energy and nutrients in the blood and tailored to each individual patient. A number of practical guidelines for patients who start a healthy diet should be taken into account for the reduction of dietary risk of eating low-fat sugars. The dietary implications of this diet should also be that the dietary effects of a person with a reduced blood sugar intake should be more balanced with those of a reduced body fat intake.
