Ok, I need to vent, lol! I have been on my pump since 1/8/15 and my numbers have been improving and I love my pump. Problem is…When I was doing my "middle of the night" test, I learned that between the hours of 5-8am I am spiking??? No food, I am counting carbs and bolusing as I should. I have tried to contact my nurse educator, but no luck. Btw, also have to bolus for my coffee in the morning, grrrr…End of rant.

But, straight coffee does NOT buy any "bolus"… (because nothing in it which has sugar).

Also spikes are NOT automatically because of something we have eaten. They can be because of some mistake we made at some point earlier in the day and the "spike" reflects that sudden drop/technical low and we did not catch it, just as easily.

Spikes are usually but not always food!

Have you also considered the DAWN effect for the "spike(s)" you discovered? Give the time frame, I'd look in that direction too rather than any food spike… Unless you're eating massive fatty food, a spike at that time frame would be unlikely that food as the regular "culprit".

Black coffee CAN affect your BG as my nurse educator had seen it happen. But goodly the changes she made today will work. She had me increase my basal rate from 1.75, adding a 2nd basal rate of 1.90 from 5am-8:00 am too determine if it is the Dawn Phenomenon. She also increased the #of carbs pet cup of coffee to 6. BTW… Stress, sickness, and such also affects your "spikes"

I am aware of the "also's" -wg-, it's not my first dance… any prayer your educator is also one of us, (prefer them best of all).

Hope your pump works "better" than it did for many of us… Will never be a fan, but perhaps it will work for you.

My dawn phenomenon went away since being on the pump. Started pumping in June. I finally got my nighttime basal rates to where i am under 100 in the morning. Last three days i have done a tbr increase of 10% for 24 hours cuz my numbers were gradually raising. The increase has me back to normal and so today i am going to increase my numbers 10% across the board

Thanks Kimfing… I just received a reply email from my nurse educator to upload so she can review what's going on and make any changes. I really do not like being under 100 as I feel crappy , but I know I need to make myself come use to it. Currently I have only one basal rate set which is 1.75,I'm thing she'll have me set one for 5-8am. Wish me luck!

When I first started this journey,(I use insulin only), I would get the shakes when I dropped into the 90s. My Dr. said it was just my body trying to get used to lower bg levels and would even out. It did and this morning was at 77 with no bad feeling. Like that number!

Under 100, its understandable why you'd be "nervous".

If you truly do not LOVE how it feels… tell them you want a couple extra points to work with… under 100 is jsut too tight for "now"… and you want to be comfortable. You can always tweak it further…

I actually have 5 basal rates set for different times of day. The lowest is from midnight to 3 am and the highest is from 3 am to 7am to counteract "dawn phenomenon". There is also an "insulin sensitivity" factor programmed into your pump which sometimes needs to be adjusted. I started out with a sensitivity factor of 120 and now it is 105. Your endo will calculate this by how many units of insulin you are using per day. It takes time and patience to get all the settings just right.

I only have 1, which I can understand just starting out. My basal rate is 1.75 and my insulin sensitivity is 19. I never heard back from my nurse educator today after uploading my pump. So I guess it is a waiting game

Yes they start of conservative so u don't go low. You are welcome. Glad u have arresponse from her. You will find for different parts of the day you may need more or less. That's the fun of fine tuning. Good luck

Yes, I agree with Lou, it is most likely the Dawn Phenomenon. I'd suggest mentioning it to your doc. I'm glad things are working so well with the pump. Keep up the good work. Heidi

Type1Lou…i am so disappointed I did not even consider the Dawn Phenomenon. I must be brain dead, lol! Thanks for jogging my memory ;-)

You are most likely experiencing something called the "Dawn Phenomenon"
which causes rises in BG in the early morning hours (3 am to 6 or 7 am. I've been struggling with it and have had to increase my morning basal levels to deal with it. Something to definitely talk to your medical team about. Also, there have been many discussions here about Dawn Phenomenon…go up to the "Search Diabetic Connect box in the upper right corner and type it in…for more on this. There is also something called the Symogyi (sp?) Effect that can cause high BG's. I'll try to find more informative links for you and edit with them if/when I do.
