Insulin is a hormone secreted by the pancreas and plays an important role in balancing blood sugar in the body. However, some people can cause an imbalance in blood glucose concentrations due to the ineffectiveness of insulin, which is called Insulin resistance. Insulin is not used properly in cells, resulting in increased blood glucose and prediabetes production.

Effects of insulin impedance

Unfortunately, there are no signs of insulin resistance. Some patients with insulin impedance may have Acanthosis nigricans, with large black plaques behind the neck, groin, armpits. Insulin impedance may silently destroy blood cells when you are not aware, increasing the risk of heart disease and Stroke. Insulin resistance may also be a precursor to Type 2 diabetes. Typical diabetes symptoms include extreme dry mouth, frequent urination, abnormal hunger, tingling as well as abnormal exhaustion.

Confirmation by blood test

Because there are no obvious signs of disease, insulin impedance (and further prediabetes or diabetes) usually rely on blood extraction for diagnosis and HbA1C to detect If the blood glucose concentration is higher than in the past few months, this test does not need to be performed on an empty stomach.

The HbA1C detection value is below 5.6%, within the normal range.

The HbA1C test value falls between 5.7% and 6.4%, prediabetes mellitus.

HbA1C test of 6.5% is diagnosed with diabetes.

Your attending physician may select a day to confirm the test results. In addition, if you perform an overnight fasting blood glucose test, the result will be the glucose level on an empty stomach. You may need to do a second test to ensure that the test results are correct.

Fasting blood glucose level below 100 mg/dL is normal.


Fasting blood glucose falls between 100 to 125 mg/dL, prediabetes.

Type 2 diabetes is diagnosed with fasting blood glucose level of 126 mg/dL.

As you age, it is recommended that you undergo regular tests to confirm that you are at risk of diabetes or other diseases at any time.

We recommend that you undergo testing as soon as possible if you meet the following conditions:

1. Lifestyle with less movement

2. Low good cholesterol index, high triglyceride, high blood pressure

3. Family history of diabetes

4. Ethnic origin (e.g. Amerindian, African American, Latino, Asian American, Pacific Islander)

5. A potential group with insulin impedance

6. Gestational diabetes during pregnancy

7. Babies weighing more than 4 kg

To keep insulin and blood cells working properly, keeping blood glucose levels within the ideal range, it is important to lose weight and maintain standard weight. It is also important to maintain an active lifestyle. Remember that confirmation of insulin resistance or pre-diabetes is a warning from your body, but if you have a healthy lifestyle, there is often a chance to get blood glucose back to normal. Although insulin resistance may come to you secretly, you can beat it with a balanced diet and daily physical activity.
