How can I know if I have Prediabetes?
The normal fasting glycemia (blood glucose) range should lie between 70 and 100 mg/dl. If blood glucose levels lie between 101 and 115 mg/dl, this can be considered as prediabetes.
In this case, a test called “Glucose Tolerance Curve” will help us know how large our risk of being diagnosed with Diabetes is. The glucose tolerance curve shows us how our insulin is responding to glucose intake and therefore will tell us if we have any degree of insulin resistance, glucose intolerance or prediabetes.
Overweight or obese people are more likely to develop Type 2 Diabetes. This happens because excess fat stored in the adipose tissue, especially around the waist, causes cells to increasingly lose their sensitivity to insulin signals, i.e. become more insulin resistant and glucose intolerant. If your fasting blood glucose is greater than 115 mg/dl or Hemoglobin A1C is greater than 5.7%, you may have prediabetes. Pre-diabetes is the stage prior to being diagnosed with Type 2 Diabetes, in which, with some changes in your lifestyle that include, among others, acquiring healthy eating habits, increasing physical activity, losing weight and strictly following your doctor’s instructions, will help your cells regain sensitivity to insulin signals and therefore, reduce your risk of developing Type 2 Diabetes. The Diabetes Prevention Program (DPP) showed this conclusively, so if you have prediabetes, following these recommendations may reverse glucose intolerance or insulin resistance and, therefore, prevent a Type 2 Diabetes diagnosis, allowing you to have an excellent quality of life.
