Yes. Internal medicine is a primary specialty for evaluating insulin resistance, prediabetes, and diabetes risk. The clinician integrates symptoms, family history, clinical metrics (waist circumference, blood pressure), and labs (fasting glucose, HbA1c, fasting insulin, lipid profile). If needed, they may order an oral glucose tolerance test (OGTT) or additional diagnostics. When risk is elevated, a structured lifestyle plan and follow-up schedule are defined; medication or referral to endocrinology may be considered in selected cases. The operational advantage is efficiency: starting with the right specialty reduces wasted time and fragmented testing. If symptoms are persistent, internal medicine is an appropriate first stop.
