They explain how pre-diabetes is often misunderstood and outline the metabolic changes that lead to elevated blood glucose and hemoglobin A1C levels. The conversation highlights the importance of recognizing the gradual buildup of insulin resistance over many years and its wide-ranging health impacts, including increased risks of heart disease, kidney failure, and chronic inflammation.
