By now we've pretty much seen it all when it comes to basal rate variations, from times where she needs 5u/hr to needing no basal, but these times usually last a few hours at most. The past few days, with her standard basal program (around 1u/hour most of the day), her BG has been constantly in the range of 60 to "low" on the CGM (under 40) despite basal suspended and massive eating. Yesterday she ate 180 carbs (juice, glucose tabs, meals, snacks) between 3 PM and 11 PM with no boluses and basal turned off for all 8 hours. Every time she ate, BG would rise up to 45 or 55 then fall right back down. Finally she at a 60-carb dinner without bolusing and her BG finally came up to 120 around midnight at which point I turned her basal back on and she stayed in a good range until morning. Today, she turned off her basal pre-emptively at 9 AM and it is still off now, 19 hours later. Her BG was better, hovering in the 70's most of the day although it dropped low a few times and she needed to eat. She bolused only for her meals today, and post prandials were normal, BG went into the high 100's then came back down. She feels fine, no indication of sickness, no eating issues, no digestive issues or any discomfort other than feeling perpetually low. The sensor is good (BG checks match the readings). It's not the pump (omnipod) as the problem has persisted though two pods, including 6 hours in-between pods when she had no pod on at all. She is just tired of having to eat so much food. Has anyone experienced this kind of prolonged intolerance of basal insulin with a teenager?
