Insulin resistance early markers: what shows up before A1c moves

A1c can look normal while insulin resistance is already progressing. Early markers such as fasting insulin, triglyceride patterns, waist trend, and post-meal response provide earlier warning. This guide explains what to track before prediabetes becomes obvious.[1][2]

Fasting insulin can flag risk before A1c rises.

Early marker tracking enables prevention instead of late reaction.

Behavioral intervention remains first-line for early resistance drift.
