I’ve noticed a few oddities in my blood sugar levels, for which i’m trying to determine the source. Here is what I’ve noticed:
I’m very sensitive to insulin-good and bad here
(Carb ratio 1 unit:15 g carbs or 1 unit:17 g carbs depending on time of day, correction ratio 1 unit: 85 mg/dL and 1 unit: 70 mg/dL depending on time of day). The carb ratio seems normal, but the correction ratio seems an unlikely pair. My doctors say that it’s much more common to see a correction ratio of 1:25 or even 1:50, but that mine seems very strange, especially given my carb ratio…but this is what works most of the time. Fluctuations are very common, even on a low carb diet…That said, I monitor/respond well, so my A1C is and has been 6.9 or lower for over a decade
The lower the amount of carbs I take a day, the higher my basal rates need to be (I don’t understand why this is).
My basal need changes significantly when I fast, but then increases significantly ~15 minutes after I eat protein (Basal rate drops to 0.85 U/H without food for 12 hours but then need increases to 1.3 U/H 15 minutes after eating protein with no/very low carbs). This seems strange. Any thoughts on this?
Often when I drink caffeine (without sugar) my blood sugars will rise to ~250 mg/dL for ~3 hours and are almost completely unresponsive to insulin during this time (any thoughts?).
Potentially unrelated, I’m very sensitive to light (especially fluorescent light). My opthalmologist and retinal specialists claim that my vision is near perfect and that I do not have any signs of damage. I’ve also been assessed for migraines, but none of my physicians seem at all concerned about these symptoms. Therefore, no one is looking into it…I only have a slight astigmatism and prescription. I’ve tried hydrating eye drops with no additives, with very little improvement. The light sensitivity is such that it is difficult to go outside and to drive at night. It is also difficult to read, especially from a computer or phone screen. It improves slightly with proper hydration and the drops, but not totally. If anyone has ideas about this, I would appreciate hearing what you have to say.
