Hi guys, I wonder if anyone has experienced a similar problem...

My fasting blood sugars this morning were 4.7mmol/l (which is fairly typical) so I got up, had my morning doses of novorapid (8 units) and lantus (16) had my breakfast (two slices of toast) and biked into work (6.5miles ish, 30mins). I arrived at work at 7:30, BG=12. 9:30, BG=17... before lunch BG=13.

This happens whenever I bike into work. Sometimes they will come down in the afternoon, sometimes in the evening, sometimes not at all :-S

It's one of those annoying things that exercise will push BG up in some people. Is it worse when your B is higher?
Have you tried having eggs and/or bacon for breakfast instead? If you do, keep monitoring BG, until you know what happens and reduce your Novorapid for the reduced carb breakfast. It's worth a try anyway.
 
Hi there,

Yeah it is worse when they're higher, but I have tried low carb breakfast AND having breakfast after the bike ride... same result, not to mention I'm exhausted biking without my carbs :(
 
Emma Jo read all the stuff posed by Fergus. He's a keen cyclist and A T1 who keeps his BGs very tight.
 
I did 6 miles before breakfast this morning on my exercise bike. I had a very bad day yesterday :? falling from the healthy living low carb waggon (although not quite as far or as hard I used to fall pre-diagnosis). My fasting level this morning was 6.7, it is usually under 6 and much closer to 5 and sometimes under 5 if I exercise later in teh evening.

My levels after 30 minutes in the bike were 8.5, then 8.7 about 30 minutes after that :shock: :shock: i have tested after my 30 minutes in teh eveneing and my levels are often under 5.

It was odd, because I had that shaky low blood sugar feeling, even tho my BS was so high, which was why I did some additional tests. Vrey odd.

I am going to assume this was a liver dump and that maybe my body was waiting for me to go out and catch me mushroom or something, for my lovely sunday morning veggie fry up with my son.

Anyway, does exerice at different times of the day have an impact on BS?
 
Controlling blood sugars is a steep learning curve. They often drop during, immediately after or several hours after a workout. Or conversely, what seemed a reasonable level to start on becomes high by the end of the session.

If a blood sugar becomes too low you may exhausted like you can’t go on (different to a non-exercise related hypo) and maybe cannot perform nearly as well when it rises.

Lack of fuel (glycogen) being converted to energy in the muscles is the cause of both – all the energy has been used in the case of a low blood sugar and not enough energy converted in the case of a high one.

Have a look at this site which has a section specifically devoted to Diabetes and all Sports etc. Might be useful ?

When I came back from the shops before lunch my BS had fallen to 4.9, it isn't usually at that level during the day unless I have exercised immediately beforehand.

Very interesting website, I have added it to my favorites and will be checking back.

I'm not sure how much of an issue this is for me as I'm not on any medication, but can I make the assumption that spikes from exercise are to be avoided as much as spikes from food?

We are all going to have 'spikes' from food and excercise. Fact of life. None of us is ever going to have a completely flat Bg reading throughout the day. The spikes shouldn't be too high though. Remeber the guideline levels ?

What needs to be avoided is consistent 'spikes' meaning you need to adjust foods or excercise levels and effort. If the 'spike' subsides and Bg levels get back to near normal levels in a relativeley short time then there is nothing to worry about.

Ken.
 
cugila, do non diabetics have 'spikes' or are they confined to the diabetic club?
 
As far as I am aware anybody can have a spike, depends on what sort of foods are eaten.
A non Diabetic can deal with it better and get back to normal a lot quicker.
