Please can I have some opinions on testing bgl? Should I test an hour or two hours after food? When I had gestational it was two hours, on diagnosis recently the Dr told me an hour, ( but I did two hours) so recently I have alarmed myself by testing an hour after and sometimes getting high spikes which usually drop well but still a little high.
Hi Carolyn, I note that you are T2 on metformin, as I am.
When I was eating the NHS/Duk high carb diet (up to 8 years ago) my 2 hour BGs were below 9, & my HbA1c around 7, so it seemed I had satisfactory control.
Complications developed, particularly crippling peripheral neuropathy.
7 years ago I change to a low carb diet & my health rapidly improved, & I was out of pain in 3 months. 2 hour testing was better, & there was a improvement in HbA1c
For test purposes I have tried testing in 1,2,3 hours after eating, carb or low carb. The 1 hour reading after a cereal (high carb) breakfast tends to mid-teens, whereas low carb is below 9.
2 hours they are about the same - 7-8
3 hours & high carb is below 5 & I'm hungry; whereas low carb is 6-7 & I'm ok.
My understanding is that the one hour spike with high carb does the damage to the body. It is worthwhile testing after 1 hour & modifying what you eat to eliminate that spike. The HbA1c is an overall average & does not pick up spikes nor lows.
Hope that helps.
