Hi.

Previously I found through exercise I struggled with hypos - bs raised slightly after exercise and then fall quickly.

Since Wednesday I have been on Byetta.

Since being on Byetta have had perfect BS in the 5's and 6's.

Last night I did my first bit of exercise since injecting - played tennis for 1.5 hrs.

Afterwards I was quite shocked to see my bs had gone as high as 12.8.

I dont think they have ever gone that high.

Could this be a side effect of Byetta?
Is it okay to exercise if this is happening?
I thought we were supposed to exercise to bring our bs down, so is this suggesting I shouldn't exercise now? Gosh I hope not!

Not sure if this affects it but feeling very sicky due to injection at the moment, but just had to exercise.
 
Whenever I exercise, my BS always goes high. I was told I was doing too much..I was only walking!

I must admit it was hard work - but I always thought we were to exercise to bring our sugars down when high?

I am sure it is nothing to worry about but just want to understand what is happening.
 
I questioned it with a nutritionist...she said yes exercise is good, but too much will push you BS high. On that assumption, i can't even walk my kids to school!
I don't understand how this whole thing works...so I will leave it to the experts to explain!
 
Exercise

My BS drops 2 to 4 points on exercise ie 30 mins on treadmill, distance 3.5-4.0km, it seems the higher the start BS is the greater the drop
 
Hi Lucy exercise can raise your bs, but i don't know the science behind it. I'm sure someone will come along who does.

Mine raises now and again when I run, but not all the time x
 
I wouldn't think this would stop you exercising - exercise should be a priority so any associating problems with BG can be ironed out. If it's only happened once it could be a coincidence so I'd just keep an eye on it for the moment. If you find it happens most times you exercise I wouldn't stop the exercise but talk to DSN or doc to see what your options are.
 
When I do a new activity, something competitive or more strenuous than usual my readings can go up. I have wondered if it is due to the release of adrenalin? I have found it a bit scary and did more exercise at home until I became more confident.
 
No experience of Byetta I'm afraid, but I have seen posts where folks find different levels of exercise do different things to BG. Alan in particular had a very odd thing where he needed to eat carbs after a run to *prevent* his BG rising.

In general low-moderate seem to reduce BG, partly by increasing insulin sensitivity. There's also something (which I can't quite remember) about cardio where muscles release energy (glycogen?) to fuel the exercise, then need to 'suck it back up' from glucose in the blood to replenish their stores, a process which I think happens directly (without needing insulin) though I'm a bit fuzzy about that.

On the other hand I've seen a tip for people who find they go low after cardio exercise to finish the session with a 30s - 1min flat out sprint. Something about the adrenaline released at maximum effort causing a burst of glucose from muscle/liver stores preventing the post-exercise dip.

Is there anything on www.runsweet.com that might give you food for thought?
 
Am on byetta, but think the BS levels soon after exercise can vary tremendously on a person by person basis, and indeed vary within one person.

Sometimes mine are v high just after exercise, sometimes low, sometimes they crash about 3 hours later!

After going onto byetta so recently, your body has to go through a process of trying to almost fight the new drugs before it realises it is actually there to help it.

My firm belief is to not take too much action over any individual BS measurement (for T2's that is, cant speak for insulin dependants). The body is a wierd thing and does lots of different things to try to compensate for what it perceives as abnormal activity or food, so we cannot guess at what stage of its cycle our instant BS reading is.

Keep records for certain, as they will be invaluable for a trained professional to make their best guess, (and that is all they do too), in the medium term but keep exercising and eating healthily.

Tonight BS dropped from a very high 12 to 5.2 after 30mins exercise, decided to do another 15 mins at same rate and it rose to 5.7, only been diagnosed just over 5 weeks so still trying to get things under control
