Prediabetes and insulin resistance occur when the body’s cells become less responsive to insulin, causing blood sugar to rise and forcing the pancreas to produce more insulin. This hormonal imbalance often develops silently over time, contributing to weight gain, fatigue, brain fog, and inflammation. Left unaddressed, it may progress into type 2 diabetes or fuel other chronic conditions. Functional medicine evaluates the underlying causes—such as high sugar intake, poor sleep, chronic stress, toxin exposure, and inactivity—and offers a personalized, sustainable approach to reversing insulin resistance and restoring metabolic health.
