Honeymooning & exercise... Type 1 Currently managed with metformin only

My BG is almost stable as I am low carbing. But i find my BG spiking unreasonably after an exercise though not so significant. I want to bring this down & dont know whats wrong with me. I do only mild intensity exercise for 30 minutes per day. My BG is quite good before exercise too

Exercise can often cause a rise in blood sugars due to the release of adrenaline which helps kick start the liver. It is rather contradictory but this generally only happens for a short period and to a limited effect. In the long run it will generally bring your levels down so be careful when you go to insulin not too try and correct these rises as they will often start to drop of their own accord. I wouldn't want to comment too much on your case as I don't really know much about Type 1 controlled only by Metformin but I don't think this is too strange. Honeymoon period is often difficult but when you go on insulin you may well see this changing.
 
I am not sure whetner T1 can be managed with metformin alone.
 
T1 s definitely cant be on metformin alone. But in the honeymoon phase as ur pancreas kicks in again u ll need only minimal or no insulin at all.Metformin improves insulin sensitivity, so my doc might have prescribed that

B4 lunch 131mg/dl
Postprandial 207
Did cycling, at the end of 15 minutes 150!
Next 15 min 137
Next 15 min 92
Stopped here
Morning fasting 123
After a 15 minutes walk 133
So discontinued @ this point.
Confusing a lot

When you say "postprandial", how many hours after lunch? Your honeymoon insulin is probably a phase 2 (slow) response not a significant phase 1 (quick) response.

Also the rise of 10mg/dl is less than 10% and probably within the margin of error for your meter. So doesn't necessarily mean anything. Or it could just be the "waking rise" which is a minor echo of the "dawn phenomenon", and caused by hormones.

Hi. Being T1 and moving from insulin to Metformin to me is quite strange. Typically you would go thru Metformin and then the insulin stimulating drugs Gliclazide and Sitagliptin thru to insulin. Then you might start on once a day Basal insulin and then add Rapid. Your doc has moved you from one extreme to the other; very unusual. How were you diagnosed as a T1?
 
Hi
If my response is only phase 2 shud i ask for a rapid acting insulin so that i can take that before food?? Postprandial is exactly 2 hrs after food. After dinner to my level has spiked much which is gradually coming down now. And morning I ll be in the normal range. Dont know how to keep in control

Yes I think it might be worth asking for a rapid acting insulin for bolus use. This should help to preserve your remaining insulin production longer. You are low carbing which is good, but as you are still getting some high readings you may be having specific reactions to some of the foods you are eating.

Because you probably only have the phase 2 response your blood sugar is still probably coming down after your 2 hour postprandial check. As it also would be with a quick acting injected insulin. Only a non diabetic person with a good phase 1 insulin response would have no more insulin action after just 2 hours.

Thank you so much spiker. Certain foods affect me much. Yesterday before bed my BG was in 200, i had a fruit & some snacks too, morning its 118. If I am taking rapid acting, i am afraid going low in the night. Otherwise i ll b happy to preserve my beta cells

Hi
My doctor has asked me to take novorapid before meals. Hope the postprandial spikes will b no more. I will start this by weekend i think. Any advice appreciated. My c-peptide values arrived today & they were at the lower limit of normal values. But no phase 1 insulin response. So sad

It is sad about your phase 1 response, but that is usually the first thing to go, so it is to be expected. Your beta cells were probably working their socks off to create that low-normal c-peptide level, and try to mop up all your blood glucose with the phase 2 response. What I expect you will see with the Novorapid is that your beta cells will get a rest that should extend their lifespan. Instead of doing the heavy lifting, your beta cells can do the fine tuning. So hopefully you should get very good blood sugar, apparently "by magic". You will feel much better, your blood sugar will be much better, and your beta cells will last longer.

Yea I am happy about that spiker Thank you for all encouragement. I am a medical student just entering the clinical year. Its surprising I never understood diabetes as I understand now after I got it Hope I will be a good doc in future by God's grace
