I believe they have briefly checked my thyroid but I will have them recheck, I appreciate that comment, as far as the iron, they mention I am anemic and had very low D which I have been taking prescribed D dosages and multivitamins to help increase those numbers. Everything under the sun has been negative except the titer ANA and the light chains, but nothing seems to worry anyone so far I guess minus the prediabetes.
Thank you for the reply and things to have checked!

Such good advice because COVID blew out my thyroid along with causing heart damage/A-fib. I've gone from no meds to multiples. I was always slender. No one in pix of the past generation on both sides of my family were heavy. In the last year I've gained 10 lbs while eating less than I did pre Covid.
When I looked into vaccine injury with an organization that collects vaccine injury info, I was told such injuries happen within a few days, not 50 days. Obviously, I do have long Covid which has slowed me down, so that too may effect weight.
I have good medical care, both an endocrinologist and cardiologist. I am 78 and more than 1/2 way to 79.
