I recently took a 2-hour OGTT and was a bit confused by one of the results. While both my blood glucose and insulin levels were in range, there was a note next to my glucose results: "Please note that the 1 hour value did not exceed the fasting and/or the 2 hour value by at least 1 mmol/L. This suggests that glucose absorption may have been impaired or delayed".
Is it normal for blood glucose to not rise very much? The results I got are below. Would appreciate any help working out whether this is normal or something that I should follow up a bit more.
Glucose (mmol/L) at Fasting/1h/2h: 4.4/4.5/4.4
Insulin (mU/L) at Fasting/1h/2h: 4/34/22
