Insulin insensitivity is when the body begins to have a lesser response to insulin secreted from your pancreas. It is usually the first sign that you are developing type 2 diabetes. This type of diabetes occurs when the body can no longer control blood sugar levels adequately. This happens when your cells stop responding to insulin in the way they should.
There are multiple different reasons why someone develops insulin insensitivity (also called insulin resistance). Genetics definitely plays an important role. If you have other family members, especially parents or siblings that have diabetes, then you are more susceptible to this type of problem. Another very important factor is your weight. If you are overweight, then your body may be responding to your size with insulin resistance.
The best thing you can do for your health is to schedule regular appointments with your primary care physician
. He or she can monitor your hemoglobin a1c levels regularly. This is a measurement of your average blood sugar over the past 3 months. This is the measurement that will tell if you are developing diabetes. In addition, your doctor
can recommend changes to your diet which can help you lose weight (if necessary) and help control your blood sugars. These are the most important two actions you can take to improve your chances of not developing diabetes.
