Experts Advise Broader Metabolic Testing to Detect Disease Years Before Diagnosis

Recent advances in metabolic medicine highlight that normal blood sugar levels alone do not guarantee metabolic health. Experts emphasize that metabolic diseases such as type 2 diabetes, fatty liver disease, and cardiovascular conditions develop gradually over years, often signaled by early warning signs well before traditional tests indicate illness. A comprehensive review published in FRONTIERS explains that metabolic syndrome, a cluster of risk factors including abdominal obesity, insulin resistance, high blood pressure, elevated triglycerides, low HDL cholesterol, chronic low-grade inflammation, and oxidative stress, significantly raises the risk of these diseases.

Key indicators beyond blood sugar tests include waist circumference, which reflects metabolically active abdominal fat producing inflammatory substances; triglyceride and HDL cholesterol levels, where high triglycerides and low HDL often precede diabetes diagnosis; and blood pressure, where mild but persistent increases may indicate metabolic disruption. While glucose and HbA1c tests remain important, they do not capture early insulin resistance, which can be detected by fasting insulin tests increasingly used in metabolic clinics.

Slightly elevated liver enzymes may also signal early metabolic-associated fatty liver disease (MASLD), a common manifestation of metabolic dysfunction. The emerging approach in metabolic medicine advocates for an integrative assessment considering multiple biomarkers alongside lifestyle factors such as sleep quality, stress levels, diet, physical activity, muscle mass, and emotional wellbeing.

Research shows chronic stress, poor sleep, and inactivity exacerbate insulin resistance and inflammation, accelerating metabolic disease progression. Conversely, Mediterranean diet, regular exercise, quality sleep, and stress reduction techniques improve metabolic health and reduce cardiometabolic risk. This holistic perspective enables earlier intervention to prevent or delay the onset of diabetes, fatty liver, and heart disease, maintaining health before clinical disease develops.

Dr. Galina Shenkerman, an endocrinologist and internal medicine specialist at MEDBALANCE, underscores that this broader evaluation complements conventional medicine and offers a more complete picture of metabolic risk.
