A: The yo-yo.
(Just a joke- I love yo-yos, actually).
This has been so far the worst 24 hours of blood sugar I've had while wearing the Dexcom and shows no signs of letting up. I suspect it may qualify as my worst blood sugar day in the past year, although maybe that's because other days are not so fresh in my memory.
Last night after supper I had a stomach ache and went hypo. My blood sugar according to the Dexcom spent three hours in the hypo range despite me eating a huge amount of sugary stuff. When I checked on my meter, the Dexcom said 50, meter said 55. I went to bed as the numbers were rising (I was around 100), suspecting I'd go high.
My numbers went up most of the night, and I corrected around 5 AM (270). When I got up a few hours later, I was going hypo (apparently I overshot with the correction). The Dexcom said 73 and the meter said 70. The hypo did not respond quickly and I went to LOW and stayed there for a while. I ate candy an then a muffin, trying to rise a little more quickly because my brother was waiting for me so we could walk to the synagogue together, and figured I'd inject when I came up a little bit. I injected as my blood sugar got up to 100.
A half hour later in the synagogue, the Dex read 199 with two arrows up and I injected a little more.
An hour later, the Dex said HIGH, the first time I've seen it do so. I decided to simply wait.
Soon it began to plummet. By the end of the service, I was dropping rapidly, and on the walk home I was back to LOW. I finished going home, ate, injected a small amount, came up a little, dropped back down. Throughout the afternoon, my blood sugar would come up to about 110 before plummeting. When I checked on my meter while the Dexcom said 58, the meter said 41.
As the Sabbath ended, the numbers suddenly started soaring upwards. I went from 70 to 350 in about an hour. Right now the number is 324 dropping slowly.
To recap: I went from under 40 to over 400 in two hours, and in less than another hour was back down to under 40. The insulin I've been taking has shown itself to be promptly effective, but the food seems to be kicking in with much delay. My stomach has been hurting, my neck is so tender that it hurts to swallow (and it hurts in my neck, not my throat) and I've been told I'm looking flushed.
Differential diagnosis: stomach bug, gallstones, thyroid flare up? Maybe just plain diabetes weirdness.
Anyways, the plan for the next 24 hours is to lower the Lantus dose (from 8 1/2 to 7), be conservative with corrections (I'm going to use a 100 ISF instead of a 60), drink lots of fluids, check ketones (have not done that yet), and eat small meals if I can.
My rationale is that hypos are going to be very hard to treat, so I don't want to go there. Eating large meals that don't digest will set me up for more problems than small meals that don't digest, and maybe I could digest smaller meals better anyways).
If this keeps up, and I check a high number on the Dex and find that I really truly am over 400. I'll call the endo on Monday. I don't remember seeing a number over 400 in the past year. I feel crummy!
I wanted to do a fact on math skills in children with type 1 diabetes but couldn't find my source. Then I got distracted reading about numeracy. Then I read a study with a lower amputation rate than I had expected, looked for more studies, and decided they disagreed with each other too much for me to feel like I have a solid fact about them.
P.S. Whoa, Nelly. My Dexcom was still reading over 300, and it was time to calibrate. The meter said 197. :-/ Not great but way better. Maybe trusting the meter on the higher numbers was the problem.
So here's a fact that is probably already known to most of my readers:
Symptoms of high and low blood sugars are different for different people at different times. The same person may have different symptoms for the same blood sugar on two different days. Symptoms for most people change over the years and threshholds vary.
You may not have symptoms with a high or low blood sugar. Conversely,you cannot be sure of a high or low blood sugar merely because of symptoms.
I get kind of annoyed with people who think they have low blood sugar but have never tested, and I was really put off in a book I read on organ transplants in which the author (who had a liver transplant but no diabetes) claims that diabetics learn to feel their blood sugar levels to the nearest 10%.
No, sorry, it doesn't work that way.
