Why was my post prandial peak after 3 hrs

[Joepubli]

Would appreciate some help with some questions. I am T2 on Janumet 50/1000 twice a day. Have got one of these Freestyle Libres and am trying to understand the results.:

1. . I thought I read that the peak should come within 2 hours. Should I be concerned that it was 3 hours? I

2. is it how high it goes that matters or is it the area under the curve 180mg/dl - so a bried spike to 200 is better than a prolonged time at 190?

3. What should be the zone (max and min) that I should try and stay in. I set 180mg/dl is that right?

What had you eaten?

The time when the peak crabs hit depends on what you eat.
For example, those treating their diabetes with insulin know about fast acting carbs such as jelly babies which hit within 15 minutes. On the other hand more fatty foods such as curry can impact our blood sugar 4 or 5 hours after eating.
The advice to test after 2 hours is a convenient approximation wen most foods will have reached their peak.
