Increase in reading after exercise

[kim2023]

My reading this morning was 6.6 and I went for run without eating anything . I just tested myself 15 mins after the run and it’s 7.9 .I googled it and it seems like adrenaline increases your blood sugar.geez you can’t win

Does anyone else experience this increase? How frustrating

Yes non-diabetics experience it to.

Your liver is tapping up your fat stores to produce glucose to fuel your run, perfectly natural.
Induces weight loss & increases your insulin sensitivity over time.
Keep the running up.

My only tip would be to have your breakfast first, allow yourself something carby, perhaps a slice of toast if you wish.
Then you'll burn off that glucose throughout the run.

Yep. The harder the exercise (eg a hour or so of football) the more glucose my liver adds to my bloodstream for fuel. It seems a perfectly natural response to me. I've found that after I stop bgs go back to where they were before really quickly - but probably more like 45 minutes or so.

I'm not doing the exercise to reduce my blood glucose, except in the most general and long-term sense of staying active and mobile.

Mild or moderate exercise reduces my bgs (a bit) as the liver never gets engaged .

Everyone does, it's how we have evolved, it's how we managed to chase down our dinner before supermarkets existed, it's just our liver doing it's job, there's no point getting frustrated, just accept it and concentrate on what you can control.

@kim2023 I otice you exercied as soon as you got up before eating anything. Are you sure the rise is due to the run rather than due to he dawn phenomenon/foot on the floor?
And does the rise continue? As well as a rise immediately after exercise not being uncommon, it can result in an overall lower level for the next 24 to 48 hours.

Everyone does

No we do not!
Whilst the logic about liver releasing glucose is true for all, it is not the case that this will result in high blood sugars. It is common for cardio to result in more efficient use of insulin so our levels can go down. This is why you will read about people with Type 1 experiencing hypos when doing cardio or long athletes "bonking" ("the point at which the body's glycogen stores are depleted, your blood glucose level drops, muscles tire and the body starts to fatigue and burn fat").
This is a case where we are all different and find exercise affects us differently.
I explain the affect of exercise on my levels with cycling
- if I pootle along the flat tow path chatting to a friend, my levels are unaffected
- if I sprint for a few miles, my levels go down
- if I slog up a steep hill against the wind on a cold wet day, my levels go up. I hate cycling in the rain and wind and I am not a fan of uphills - it stresses my body.
My fit non-diabetic partner experiences something similar ... although he is better at uphills than I am.

Yes perfectly normal for me, but after a 50 min workout I am not surprised to be honest. I exercise to help reduce my bg and keep active, maintain weight and sanity!

Thank you for the link as I always thought non diabetics stayed in the same reading range no matter what they ate .
Great tip about breakfast. Thank you

Thanks for the reply . Will test myself an hour after exercise to see whether mine drops too

What is the Dawn phenomena? Never heard of it . I ate chicken and vegetables the night before and my reading was 6.6 within ten mins of waking up . Does it tend to keep increasing in the morning?

That doc is a low carb eater, those spikes are a function of his low insulin levels due to his diet. He could turn the taps on again were he to return to the standard 300-350gs carbs per day diet.

At the start of the day, our liver releases glucose to give our body the energy we need to start the day.
Most people experience this whether diabetic or not.
Those without diabetes will not notice it because their healthy pancreas will release enough insulin to convert this extra glucose into energy.

As our pancreas does not work properly, it is common for people with diabetes to see a rise at the start of the day. For some this happens before they get up and others see it when they start moving (you may see this called "Foot on the Floor").
As it is a reaction to fasting, some of us find it can be tempered by eating something at the start of the day to send a message to our liver to stop with the glucose dump.

If you search (top right of the page) for "Dawn Phenomenon" you will find many threads about this and how to minimise it.

I was replying to a Type 2 on a Type 2 discussion forum, my reply was given from a Type 2 perspective. I must admit it slipped my mind to include every possible scenario for every possible type of diabetes.
