I woke up this morning at 7:30. My sensor showed I was 63. My meter showed 65. I was being lazy and restoring Windows on my computer… Yes, again! So an hour and a half later I have some black decaf coffee with a splenda in it, and my blood sugar had come up to 93. ??? Dawn phenominum?? My basal never changed during that time either. Same thing happened yesterday at work. 113 before coffee and work. By lunch, I was 269. Sometimes I just don’t get it. There’s no reason for it to go up. Anyone have a clue as to why this my be happening? I’ve adjusted my pump this morning to try and account for the downward slope from 2-5am and the climb from 9am-12pm… I guess I’ll see what tomorrow’s like.
It could be dawn phenonmenon. If I don’t eat & bolus soon after waking up, BG continues to climb as my liver dumps more glycogen. Caffeine also cause spikes. Do you eat breakfast, or just have coffee?
Mostly coffee, but sometimes breakfast. It’s decaf though. I know there is still some caffeine in it, but no that much.
The same thing has been happening to me the past week. I would be great all night long, sometimes drop, wake up perfect, have some coffee and maybe a couple eggs before class at 7:30 and by 8:30-9 it would spike to the high 100s. I just kept playing with my basal and I think I have it figured out, but it was really annoying and I just don’t understand…
Coffee (even without milk) makes my blood sugar go up. Since you said you drink decaf, I’m not sure.
MelissaBL reported with her CGM that she can spot a 30 mg/dl ride just from coffee. I bolus for about 5-10g of carb when I drink a coffee.
