I have just started having 5 injections rather than 4. I have 3 fast acting humalog and 2 split doses of levemir. I have been doing this over 2 weeks now and after exercise on an evening my bloods have started shooting through the roof even though my blood sugars are fine before I exercise! This used to happen which is why I changed onto 5 injections but if anything has got worse! Does anyone else experience the same? X

Re: High bloods after exercise

Yeah,happens with me too.
Rite now I'm taking a medication of humalog mix25.
I experienced the same,and when I consulted my doctor she told me that this happens in the very beginning when you start exercising.
Eventually,the level of sugar will start decreasing as days will pass and you're more habitual to it. Bit this will happen at a decreasing rate.
Patience is required.
 
Re: High bloods after exercise

This happens me too. I take two split doses of levimer and novo rapid with meals. My bs always shoots up after a walk. Hoping it settles soon though xx

Hi, I'm t2 and just begun to go to the gym and this also happens to me :(
 
Re: High bloods after exercise

Happens to me too. I take insulin when I exercise to avoid the highs. It happens because some exercise exerts stress on your body, your liver reacts to this by producing cortisol which raises your glucose levels.

From an evolutionary perspective this makes sense as in stressful life-or-death situations an extra boost of energy has obviously helped in the past.

I need 2 units of Novorapid when I go to the gym.
 
Re: High bloods after exercise

Thanks for all your replies! My nurse has mentioned maybe having to inject to exercise but I exercise every day and this would mean 6 injections a day!
Just feels such a fight sometimes, I have had diabetes since I was 18 months old and I am 21 now and just when I start to think I understand how it works everything goes haywire :(

Re: High bloods after exercise

Hi guys,
I'm the same, just starting back at the gym after a while out & my sugars were 17! Got home & had dinner. Do you correct for the high bs or will it drop again on its own? I did some cardio & then weights.

Re: High bloods after exercise

I used to experience this when I exercised, after speaking to my doctor found it was down to the type of exercise I was doing.
Aerobic exercise will decrees your levels and anaerobic will increase.
This explained a lot for me as I was doing a long run with a sprint at the end and not understanding why my sugars were going up!

Re: High bloods after exercise

My nurse has said the reason for my bloods going up is that I don't have enough insulin in my system so no matter what exercise I do my blood sugars will increase. I'm hoping by increasing my background insulin this should cover my exercise and stop my highs.
If i am very high after exercise then I inject some fast acting to bring me back down
 
Re: High bloods after exercise

When you exercise you will need less basal as exercise produces another hormone that makes your cells more absorbant. Ever noticed hypos after exercise? Well thats why. The effects of exercise last up to about 48 hours. I reduce my Lantus by 20% during this period.

You most certainly do not need to increase Lantus because of exercise as this will cause hypos.

Here's my routine: 2u Novorapid before gym to cover rising BGs. 1u less Novorapid for my next meal and 20% less Lantus that evening to avoid hypos. I put the Lantus dose back to what it was after 48 hours. If I exercise in the meantime I'll need to drop my Lantus by another 20% until I plateau at 6u.

I'd recommended Gary Scheiner's Think Like A Pancreas book as that is where I learned thus technique.
 
Re: High bloods after exercise

Yep, stops the spike and dont go hypo after as I reduce the Novorapid by one unit for my next meal (I usually have a meal after exercise as I do it before breakfast or dinner).

Best way to find out what works for you is to experiment. Write down your sugar levels and keep the exercise routine consistent until you have things figured things. Probably best to be conservative as you dont want any big hypos.
