How to Determine Insulin Sensitivity for Type 2 Diabetics

Insulin sensitivity refers to the body's natural ability to convert sugars into energy. Sometimes, the body's insulin receptors do not synthesize glucose properly, resulting in insulin resistance, a condition caused by high levels of insulin in the blood. In type 2 diabetes, the most common form of adult-onset diabetes, a person has high levels of glucose in the blood because of the body's inability to break down glucose properly. Unfortunately, people with type 2 diabetes often suffer from insulin resistance and likely developed diabetes due to this condition. While there is no definitive test to detect insulin resistance, you can watch out for certain risk factors and take steps to minimize and eliminate the effects of insulin resistance.

Instructions

  1. Determine your insulin sensitivity

    • 1

      Ask your doctor for a glucose tolerance test. This test usually requires fasting for eight hours. After you fast, the doctor or laboratory has you drink a sweet liquid solution. Then, your blood sugar levels are tested. If your fasting glucose level is over 100, this could indicate insulin resistance.

      Assess your physical ability and condition. People who are overweight or obese are much more likely to be insulin resistant. Leading a sedentary lifestyle in which you get little to no exercise also increases your risk for insulin resistance.

      Determine your cardiovascular health with the help of your doctor. If you suffer from heart disease or a vascular problem, this may indicate insulin resistance. Bad cholesterol (LDL) levels in the blood, along with hypertension (high blood pressure) are both typical conditions found in insulin-resistant people. In general, LDL cholesterol levels in the blood above 160 mmol/L are considered high; you should aim for LDL levels below 100, or below 70 if you have heart disease. You are considered hypertensive if the top number in your blood pressure (systolic pressure) is consistently above 140, while the bottom number (diastolic pressure) is consistently above 90.

      Assess your energy and concentration levels. Insulin resistance can affect your mental capacity, so that tiredness you feel may not be "all in your head." Fatigue, poor concentration and diminishing memory are all possible indicators of insulin resistance.
