Interpretation of greggs breakfast please?( with the freestyle Libre 2)

[Grumpy Porridge]

Hi,

I now have the free style Libre 2 ( on a 6 month free trial )

Earlier today I had greggs for breakfast . I had a chicken and bacon toastie, one sausage roll and a regular cappuccino

all together, the carb content was 93g

with this information, and the photo included, does it look like it had a disastrously bad result or ? What blood glucose is the max for minimal impact on long term Health? And how high do non diabetics blood spike to generally ?

Thank you !

Doesn’t look too bad to me as your blood sugars came down.

however, this one “test” is as much a test of the sensor as Greggs and the timing of your insulin.
For example, when was the sensor inserted? Libre are notoriously inaccurate on the first day.
When did you bolus? If you injected earlier your injected insulin may have matched the spike.

Hi, thank you for your reply, I put the sensor on, on Saturday evening so guessing had time to adjust properly. And I had 9 units of novarapid just under 15 mins before eating ( my blood was around 5 so though it would be ok to eat then)
And I've been told to waiting 15- 20 mins anyway , is it recommended to wait longer then depending on what you eat ?
And do these levels look like 'typical' diabetes levels?

Thank you : )

Some people benefit from leaving a longer gap but not everyone.

Looking at the graph it seems you ate just before 2pm, spiked to 9mmol but came back under 6mmol 2hrs later. Without the libra you wouldn’t notice the spike at all.

You appear to be in range 97% of the time & your average reading is 6mmol.

This is all really good, well done! If you can stick to your target range your doing really well & can expect good outcomes. Complications can be unpredictable, some people suffer them even with good control. All you can do is try to stay in range & hope that it means you stay healthy for as long as possible.

is it recommended to wait longer then depending on what you eat ?

Different foods digests at different rates.
Therefore, depending upon what we eat, the glucose gets into our blood at different times after starting to eat.
For example, we use "fast acting glucose"such as jelly babies when we hypo because it gets into our blood quickly. On the other hand, something high in fat such as chocolate slows down the carb absorption and could affect our blood sugars for hours later.

Injected insulin works at the same rate - not in response o the speed at which the food digests.

In an ideal world (or a perfect body) the blood sugar peak coincides with the insulin peak and cancel each other out.
Those of us without the ideal body need to approximate the sugar/digestion peak and time our insulin injection as close as possible to match.
As with all things diabetic, we are all different - our bodies work at different speed to digest the food, we eat different food and insulin works at slightly different speeds for each of us. So there is a lot of trial and error - somethings could require an injection more than 15 minutes before eating, some less and some (especially high fat food such as curry and pizza) may require a second injection later.

Pre-bolusing 15 to 20 minutes before eating is a good approximation for most foods.
Libre graphs can show you how closely you matched the sugar high peak with the insulin peak and you can use this knowledge to adjust your dosage time next time you eat the same dish.

But don't get hung up on it - a spike where you injected "too late" is not the end of the world; it is better than too little insulin and staying high.
