Silent Signals: Early Clues That Could Reveal Insulin Resistance
Insulin resistance often develops quietly before blood sugar rises and can lead to prediabetes, Type 2 diabetes, and other diseases. Doctors watch for signs like dark patches on the skin (acanthosis nigricans), skin tags, unexplained abdominal weight gain, and fatigue after meals. There’s no single gold-standard test; clues come from insulin and fasting glucose tests or rising A1C trends, and some patients use a continuous glucose monitor to gauge dietary impact. The condition is largely preventable and reversible with regular aerobic exercise, a high-fiber, low-glycemic diet, and weight management, though CGMs can create anxiety and should be discussed with a clinician.
