Prediabetes, also known as impaired glucose tolerance, occurs when blood sugar is higher than normal, but not high enough to be classified as diabetes. Prediabetes affects 57 million people in the United States over the age of 20.
People with prediabetes may not notice any symptoms, but often begin to develop complications normally associated with type 2 diabetes before a diagnosis of diabetes is actually made.
Early diagnosis of prediabetes may help prevent type 2 diabetes and more serious health problems such as heart disease and kidney disease. In people with prediabetes, lifestyle changes and medication may prevent the progression to type 2 diabetes.
If you have any risk factors for diabetes, have a BMI (body mass index) over 25, or have other health conditions such as polycystic ovary syndrome, high cholesterol, or high blood pressure, you should be tested for prediabetes. Your doctor can order laboratory tests that determine if your body metabolizes glucose properly.
