Beau's Lines

[LonelyFatGuy]

Only noticed yesterday that I have what I believe to be 'Beau's Lines' on both of my big toenails.

Supposedly can be caused by diabetes.

I know it might not be a question that anyone can answer, but would it be known at what kind of A1c these would start to appear...? I just got an A1c of 71 from a blood test taken on Monday.

What I'm trying to establish is whether I should expect Beau's Lines with that level of A1c, or whether they are being caused by some other condition. (I suspected I might have a thyroid issue, but apparently that test came back fine, so either it's the diabetes, or some kind of deficiency / other condition).

I have these or have had them never knew what it was. They appeared on my big toe nails and I thought fungal nail and never bothered, just looked on internet and yes same
Diabetes and peripheral arterial disease i have that too. My Hba1xc was very high in Jan (129) but managed to get it down to 45 (Nov) I never gave them a second though

I have had them in the past, usually after being particularly ill - meningitis in my case. Didn't know they had a name. I'd never associated them with diabetes at all, and can't think of them appearing at any time in the last 15 years. Google/wikipedia gives lots of possibilities as to cause. The Handbook of Diabetes doesn't mention them at all.

Just checked and I might have a ridge on my nails - but I just recovered - or at least I survived, Covid and then 'flu' plus I missed quite a few days taking my thyroxine. I took a bit of a hammering to be honest.
I also did not do the encouraging of circulation to my feet with hot water and massage, and hardly ate during 'flu' - which was worse than the Covid this year.
Ah - just found a bright light to check. There are lines on my thumbs and a couple of finger nails too, not so easy to see but can be felt right at the base of the nail. Lines on toe nails are more distinct.
There are other reasons for these lines - it is not, I suspect an actual symptom of diabetes but the long term consequences of it, and I expect that they will not be a permanent feature of my nails unless I don't make a good recovery.
I was tested at least half a dozen times for failed thyroid , as I had symptoms, and when eventually there was a diagnosis my thyroid stimulating hormone level was five thousand times higher than normal. I was told that it not uncommon as the thyroid can fail and recover many times before succumbing. I had nail ridges back then, decades ago.
After some years of good control of my type 2, my thyroid has perked up a bit - back from the dead, My Thyroxine requirement is half what it was.
