How do sugar readings work?

[CaffeineInfusion]

I'll hands up say that I don't understand any of this.

Last night, before bed 5.4.

This morning, before breakfast 7.4.

I get that after eating with reading will Spike, then settle. But I don't understand why it's higher in the morning?

I'm getting so lost on Google. Can someone explain this in simple terms please?

If your blood sugar falls low overnight your liver can release extra glucose in anticipation of you getting up in the morning - try googling ‘dawn effect’.

Are you type 1 or 2? Or something else?

Fasting blood glucose levels always the last to come down in a lot of people due to dawn effect. Basically your liver breaks down fat into glucose so you are ready to go out and hunt your breakfast!
You might find the diabetes.co.uk helpful ...

Also I take medication with my meals which brings it down but then my numbers go back up again to their base level overnight as that medication wears off.

Dawn phenomenon, also, take your reading in bed, as there is ‘foot to floor’ syndrome.

I second going on diabetes.co.uk website.

Because blood sugar is not a straight line, even for a non diabetic. Hormones, circadian rhythm, a myriad of things affect blood sugar levels, not just food.
