Summary: I think my pre-diabetes went away with a change in my thyroid medication.

I wanted to share this story since there may be other people out there battling too-high blood glucose and taking thyroid meds.

I've been on thyroid meds since my late 20s. I took 125mcg daily. Seemed to work fine, but after menopause, maybe a bit before, it started to be too much. I was getting palpitations, insomnia, etc. So I cut it back myself by skipping one day a week. Eventually even with that weekly skipping of a day it felt like too much, so I finally asked my doctor to cut it down.

She did and it helped with some things fairly quickly, but my blood sugar was still too high. So it has been at least 6 months since we cut it down and suddenly my fasting BG has dropped almost 30 points. WHAT?!

I was mystified about why. Sure, my diet has been low carb with occasional oopsies, but my BG was always very stubborn. Why the sudden drop? Is it because I am exercising more? I would've thought a more gradual drop would happen, but this drop happened over the course of weeks.

I started looking into thyroid and glucose and found a connection between too-high thyroid levels and liver dysfunction and hyperglycemia. Ok, but why the delay in my blood glucose dropping then a sudden major drop? Of course, I can't 100% explain it, but my suspicion is that I had fatty liver from the high BG and lowering the dose resolved that situation over time. When it was better, then the BG finally dropped.

Stunning to go from 115-120 fasting BG in the morning to, this morning, 90!

Also, my BG drops really nicely from exercise now where it didn't before. I ate a sweet treat yesterday and got a reading of 129 (which is much lower than what I would've seen before) and pedaled on my bike for 20 minutes and got down to 91.

So... wow!
