It seems to me that I may have asked this question before. But I don't remember and am much to lazy to search for it, so here it goes:
Lately we have to give Elise her rapid-acting insulin at least 20 minutes (and sometimes 30) after she STARTS eating her dinner, or she will CRASH. For example:
Yesterday her BG before dinner was low 100s. She ate (and finished her dinner - 40g), and I gave her her shot 25 minutes after she started. One hour later she was 45.
Two days ago she was low 300s (not sure why) before dinner, so I gave her her shot at the same time that she ate. She had 35g, and about 45 minutes later was 151 with double arrows down on the CGM. I rode it out and she ended up steady in the low 100s.
She gets between 35-40g of carbs at dinner. It used to be 30g, but we usually have to give her between 5-10g when she crashes, so we just added it to the meal time. Anything over 40g, she goes high after she crashes.
It's like her body absorbs the food soooooo slowly at dinner. This is the only meal it happens at. Breakfast I can bolus her up to 30 minutes prior to eating with no problem.
She only gets 1 unit of humalog at dinner. I don't want to give less because it is so imprecise to measure up 1/2 a unit. And I don't want to go back to diluted either.
So, any ideas? Anybody have this happen to them? I know I could work around it on a pump, but with everything going on in our life right now, we have put the pump decision on the back burner.
Edited to add: This has been going on for about three weeks. We dealt with it about 3 months ago, but it went away in it's own. Unfortunately, it's back and doesn't seem to be going anywhere.
Edited further to add: So tonight she was 191 going into dinner. I gave her her insulin right as she started eating. Via the dex, her BG went down to about 150, but always with a flat arrow (her BG would lower by a few points each update). Weird. We never saw a crash, but we never saw a spike... just a flat line for almost 2 hours post-dinner. Maybe she's starting to come out of whatever this is. Glad to know we're not the only ones.
