Sugar lowers fasting blood glucose?

Tablets (oral)
Type 2 diabetic for 13+ years, 3 metformin per day + some supplements (Vitamins B12, C, D3, Krill Oil, Astaxanthin); last HBA1C 46.
Typical fasting blood glucose 6 to 7.5, then whatever I have for breakfast - bacon, eggs, toast (not all together!) or even just a glass of whey - it's 2 to 4 higher 2 hours later, depending on my carb intake, which sounds fair enough, though am surprised Dr Mercola's whey raises it as much as 1 slice toast, so was he, but there it is

But one morning was feeling down, didn't feel hungry, treated/cheered myself with a big cappuccino with 6gm sugar - hate any coffee without at least a little sugar: Two hours later, blood glucose down from 7.5 to 5.5.

Repeated this over the last 3 to 4 weeks, no solid food for breakfast, just a cappuccino with up to 4gm sugar - did I mention I can't stand any coffee without some sugar, which is why I haven't tried it without any sugar?
Anyway, whether 1 or 2 hours later, my blood glucose reading is ALWAYS lower; the higher the fasting reading is, the lower it goes after a coffee with some sugar.

Why do a few grams of sugar lower my blood glucose? What might be going on?
 
No idea, but this pointless response might bump the thread to the top of the list.
 
Seems counterintuitive but probably isn’t all that bizarre. At two hours you have likely missed the apex of sucrose. Additionally the quick energy boost is likely to discourage the liver from spilling out any further unwanted glucose, so by the time you test, things have settled. Of course there’s a million factors to consider, not least your level of insulin sensitivity, but I wouldn’t mind betting that this broadly explains the phenomenon you’re seeing. That’s my hypothesis, for what it’s worth :D
 
My only suggestion, is that the sugar and also the milk in the coffee will have caused your pancreas to secrete a large amount of insulin in order to clear the ensuing glucose from your blood stream. This in turn will have told the liver to stop dumping stored glucose - which is what happens to everyone in the mornings - and is why you see higher levels in the mornings than at other times before eating. Also, the sugar will have released the glucose into your bloodstream very quickly, so your peak will have been very early and you missed it when testing. Just my theory.
 
Also it’s worth noting that the fructose portion of the sucrose, whilst not directly contributing to blood glucose concentration, has gone straight to your liver where it has been ninja’d directly into fat, increasing fatty liver and insulin resistance. No matter which way you cut it, sugar should not be in the arsenal of any insulin resistant diabetic. Meters are overrated in many regards. They only ever tell you half the story of your metabolic health - present and future.

In my opinion :)
 
Reminds me of that song Julie whatsername sung years ago...

A spoonful of sugar helps the bg levels go down
The bg levels go down-wown
The bg levels go down
Just a spoonful of sugar helps the bg levels go down
In a most delightful way
