Question about b12. I was dx’d hypo in 2015 w tsh of 12.4 at 65. I finally got antibodies tested 8 months later and this resulted in Hashimoto dx. The results of my b12 are:
11/15 799 (200-900)
10/17 677 (200-1100)
11/18 468 (200-1100)
My understanding is that w a tsh that high, I would have been hypo for some number of years prior to this tsh value. Research suggests that b12 is stored apx for 3-5 years before one begins to go through the ‘stores’. My question is is a decline of b12 related to being hypo or having Hashimoto?
