Ok so today we had an episode with DS (aged 12, 6 months post diagnosis). At 12:38 he was 120 (he was close to 120 for 30+ minutes) At 12:43 he was 110 At 12:48 he was an 86 At around 12:48 he walked off the altar under his own power...just barely (he was serving Mass and started to feel lightheaded). A fingerstick showed him at 89. 15 carbs of juice. At 12:53 he was 76 He went up to 111 about an hour later. Last insulin was at breakfast at around 9:30. 61 carbs. 6 units His breakfast peak was around 220 at 10:20AM. We do Lantus at night. Will a sudden drop, even within range, cause a diabetic to "feel" low? He stayed above 70 the entire time. he normally doesn't feel lows until he is in the 50's, and low 50's at that. We are trying to determine if this was diabetes related, or something else. he has conked out on the altar before (twice, years prior to diagnosis). The robes they wear are warm and a little tight around the neck, and he forgot to drink water before Church. What do you guys think?
