胰岛素抵抗 中国就医指南

Insulin resistance is a pathophysiological condition in which cells—particularly in skeletal muscle, liver, and adipose tissue—fail to respond normally to insulin, resulting in impaired glucose uptake and utilization. As a compensatory mechanism, the pancreas secretes increasingly higher levels of insulin (hyperinsulinemia) to maintain euglycemia. Over time, this chronic demand may exhaust beta-cell function, leading to progressive hyperglycemia and ultimately type 2 diabetes mellitus (T2DM). The core pathogenesis involves defects in the insulin signaling cascade—including reduced tyrosine phosphorylation of insulin receptor substrate (IRS) proteins, aberrant activation of inflammatory pathways (e.g., JNK, IKKβ/NF-κB), mitochondrial dysfunction, endoplasmic reticulum stress, and lipotoxicity from ectopic fat deposition in liver and muscle. Adipose tissue inflammation and dysregulated adipokine secretion (e.g., elevated resistin, leptin resistance, reduced adiponectin) further exacerbate systemic insulin resistance.

Epidemiologically, insulin resistance is highly prevalent worldwide and underlies a broad spectrum of metabolic disorders. In China, population-based studies estimate that 25–35% of adults exhibit measurable insulin resistance—even among non-diabetic individuals—with prevalence rising sharply with age, urbanization, and sedentary lifestyles. It is a central feature of metabolic syndrome, affecting over 40% of adults with abdominal obesity or hypertension. Globally, insulin resistance contributes significantly to the burden of cardiovascular disease, non-alcoholic fatty liver disease (NAFLD), polycystic ovary syndrome (PCOS), and chronic kidney disease.

Key modifiable risk factors include excess visceral adiposity, physical inactivity, high intake of refined carbohydrates and saturated fats, chronic sleep deprivation, and smoking. Non-modifiable determinants encompass genetic predisposition (e.g., variants in PPARG, TCF7L2, IRS1), ethnicity (higher susceptibility observed in East Asian, South Asian, and Hispanic populations), aging, and certain hormonal conditions (e.g., Cushing’s syndrome, acromegaly). Importantly, insulin resistance often develops silently for years before clinical manifestations emerge—making early detection via HOMA-IR, Matsuda index, or hyperinsulinemic-euglycemic clamp critical in high-risk cohorts.

The quality-of-life impact is substantial yet frequently underestimated. Patients commonly report fatigue, brain fog, increased hunger, and difficulty losing weight—symptoms that impair daily functioning, work productivity, and emotional well-being. Psychological distress—including anxiety and depression—is elevated due to diagnostic ambiguity, stigma around weight, and fear of progression to diabetes or cardiovascular events. Moreover, insulin resistance correlates strongly with reduced health-related quality of life (HRQoL) scores across physical, social, and mental domains, independent of BMI or glycemic status. Effective management therefore requires not only biomedical intervention but also behavioral support, nutritional counseling, and psychosocial care to sustain long-term adherence and improve holistic outcomes.
