I think I have finally found a great basal amount of Lantus that keeps my glucose well controlled during the night with a perfect reading in the morning. However, as I have tried to really tighten control lately and am now using a Freestyle Libre, I’m confused by some postprandial results I’m getting. I eat low carb and after taking my NovoRapid with breakfast, I have very stable results (wonderful!) in the hours following my meal (around 97-100) in the first hour, but then after around 2 or 2.5 hours post-meal, my glucose slowly starts to climb again - usually reaching around 130 (but sometimes as high as 140 or 150) by the four hour mark. It seems like the duration isn’t working and that there’s not enough insulin for the long haul to stay in perfect range before it’s time for my next dose of insulin.
At first I thought I should try to raise my Lantus, but doing so by two units gave me multiple nighttime hypos. I think my current Lantus dose is right, at least as far as nighttime control is concerned (really stable).
I have an appointment with my endo to discuss this soon, but in the meantime, I was curious to hear if others have experienced really positive postprandial glucose levels followed by a small spike that are not caused by heavy carb load (it’s not like I’m eating pizza!). I haven’t really noticed this pattern before because I only recently switched to CGM.
