Measuring your risk of developing Type 2 Diabetes

Measuring your risk of developing Type 2 Diabetes

If you suspect you have insulin resistance or its risk factors, you need to ask your doctor to get a test called Glucose Tolerance Curve. This will help determine your cells’ sensitivity degree to insulin signals and the risk you have of Insulin Resistance, Metabolic Syndrome, Prediabetes or of developing Type 2 Diabetes.

To prepare for this test, your doctor will ask you to eat foods with a high carbohydrate content (at least 150-200 grams of carbohydrates per day) for 3 days prior to the test. He’ll also ask you not to smoke, drink alcohol or exercise for at least 8 hours before the test, so it won’t affect your results.

Warn your doctor about any medications you may be taking. Your doctor may ask you to suspend them temporarily, as some drugs can also affect your test results.

On the test day, your doctor will take a blood glucose test and will ask you to drink a glucose solution (a drink that contains 75g of glucose) to then take a blood test every 30 minutes for up to 2 hours after having had the drink.

The blood sugar test you get 2 hours after drinking the glucose solution, will tell you how well your cells are responding to insulin to metabolize the glucose you ingest, that is, the degree of insulin resistance or glucose intolerance the cells have.

One element that predicts the degree of insulin sensitivity we may be losing is our blood insulin level. Normal insulin levels lie between 5mc U/ml and 10mc U/ml. When insulin levels lie above 10mc U/ml, this means there’s excess insulin in our bloodstream and this is known as hyperinsulinism or hyperinsulinemia. Hyperinsulinemia or elevated insulin levels is the first sign that our cells are becoming insulin resistant. If blood levels lie above 20mc U/ml, it’s considered that the person has prediabetes.
