Final answer:
Impaired fasting glucose is a blood glucose level between 100 and 125 mg/dl, while impaired glucose tolerance is a level between 140 and 199 mg/dl two hours after consuming glucose.
Step-by-step explanation:
Impaired fasting glucose and impaired glucose tolerance are conditions that indicate a higher risk for developing diabetes. In women, impaired fasting glucose is defined as having a fasting blood glucose level between 100 and 125 mg/dl. Impaired glucose tolerance is defined as having a blood glucose level between 140 and 199 mg/dl two hours after consuming a glucose load during an oral glucose tolerance test (OGTT).
For example, if a woman's fasting blood glucose level is 110 mg/dl, she would be considered to have impaired fasting glucose. If her blood glucose level two hours after an OGTT is 160 mg/dl, she would be considered to have impaired glucose tolerance.
