Question

Quizplus · Accepted Answer

An individual is diagnosed with impaired glucose tolerance (IGT) if their blood glucose levels are between 140-199 mg/dL 2 hours after consuming a 75-g oral glucose load. This indicates that their body is unable to fully process and regulate glucose, which can increase the risk of developing type 2 diabetes in the future. The other options listed are either within the normal range of blood glucose (C) or indicative of prediabetes or diabetes (B, D). A blood glucose level of 140-199 mg/dL two hours after an oral glucose tolerance test (OGTT) indicates impaired glucose tolerance (IGT). A level of 100-125 mg/dL indicates impaired fasting glucose (IFG), and a level greater than or equal to 200 mg/dL indicates diabetes. A normal fasting blood glucose level is between 70-110 mg/dL. A level of 115-140 mg/dL is not indicative of any specific glucose intolerance.
