When your body develops insulin resistance, this means that you have developed pre-diabetes, which often precedes the development of type 2 diabetes. This occurs for reasons that are not completely understood. What we do know is that at some point, your body's cells begin to have a lesser response to the insulin secreted by the pancreas. This requires that the pancreas secrete more insulin to keep your blood sugars normal. When the pancreas is unable to secrete enough insulin to keep your blood sugars in check, then they become too high and diabetes is diagnosed.
The reasons that this happens is complex, but we do know that it tends to run in families. If you have close family members with diabetes, then you will be more likely to develop it yourself. Your weight is another important factor. If you are overweight then you will be more likely to develop insulin resistance and diabetes.
The best thing you can do is to schedule an appointment with your primary care physician
. He or she can measure your hemoglobin a1c level regularly (this is a blood test) which tells what your average blood sugar was the past few months. Your doctor
can also recommend dietary changes that may help reduce your insulin sensitivity and help you lose weight if necessary. If these measures do not work, then you may require a medication.
