As part of my abortive attempt to join the teplizumab study, I was given a mixed meal challenge - essentially, have 2.5 cans of a canned milkshake-type product and then have blood drawn for c-peptide and BG testing. Since I’m very solidly in (what I think) is honeymoon, I knew that my sugars would come under control, but what was interesting was the c-peptide results.
It should be noted that the “normal” range for this lab is 1.1-5 ng/mL.
Baseline (10 minutes pre-drink) was 2.3. This was a 10 hour fasting mark. Half an hour in, I was up to 4.4 and then went up into the 5.8-8.1 range for the next 2 hours. Normal c-peptides didn’t return until the 3:30 mark from drinking.
Blood sugar spiked, with highest mark at 2 hours, and then was back to normal by the 3 hour mark, and actually down to 69 by the 4 hour mark.
Am currently taking 6U Lantus at night, on very low-carb diet, and adding much exercise, with concommitant good control of sugars - I think the highest I’ve seen in the last 2 weeks other than during the mixed meal challenge was around 145, and for the last week I’ve been running mostly in the 70s and 80s during the day, with virtually no readings above 100.
I should also note that I reduced my Lantus to 4U the night before the test. Had an essentially unchanged fasting blood sugar (have been bouncing in the 110-130 range for fastings.)
Obviously, I’m going to take these numbers to my endo, but does anyone have any thoughts?
