Prediabetes

Question 1

what is prediabetes?

Answer 1

a warning sign for DM

Question 2

1/3 metabolic changes: impaired fasting glucose (IFG)

Answer 2

• 6.1-6.9 mmol/L

- after an overnight fast, BG is measured; fasting is a more precise estimation of glucose uptake, needed to Dx DM

Question 3

what is normal fasting glucose?

Answer 3

3.5-5.5 mmol/L

Question 4

2/3 metabolic changes: glucose tolerance test (GTT)

Answer 4

2-hour OGTT = oral glucose tolerance test (ingest glucose and monitor plasma levels for 2 hours)

Question 5

3/3 metabolic changes: increased HgbA1C

Answer 5

• 6-6.4% is prediabetes, 6.5% + is diabetes
• A1c is a subclass of HbA (Adult hemoglobin)
• Measurement of glucose binding to hemoglobin (the higher the levels of glucose, the more that will bind to HbA1c)
