Morning
@ChrisT2.
As you know, diabetes is a very individual disorder and we're all different. Have you monitored your blood glucose levels at other times in the day?
The most significant factor, barring illness, is the food you've eaten, so you'll learn most by testing just before you take the first mouthful, be it breakfast, lunch or dinner. Then compare that first reading with the result two hours later. The second reading should be no more than 2 mmols/l above the first one and no higher than 8 mmols/l.
If that's the case, it shows that your system dealt with the arrival of glucose (in whatever amount) in your bloodstream and cleared it relatively quickly. If not, by modifying that meal next time, you can reduce your numbers from where they are now to healthy results.
The FBG reading the next morning is usually the last to come down.
