Final answer:
An impaired fasting glucose level is a blood glucose level between 100 and 125 mg/dL after fasting for at least 8 hours. It is considered pre-diabetes and increases the risk of developing type 2 diabetes.
Step-by-step explanation:
An impaired fasting glucose level is defined as a blood glucose level that falls between 100 and 125 mg/dL after fasting for at least 8 hours. This condition is also known as pre-diabetes, which means that your blood glucose level is higher than normal but not high enough to be diagnosed as diabetes.
For example, if your fasting blood glucose level is 110 mg/dL, it would be considered impaired fasting glucose. It is important to note that impaired fasting glucose increases your risk of developing type 2 diabetes in if lifestyle changes are not made.
