I don't post very often as having had the radioiodine treatment for hyperthyroidism, I thought that my position was now permanent and I only needed the annual thyroid function tests my doctor (new this year) takes every year. I may still do.
My recent health has though taken a nosedive with ridiculous weight gain: I'm nearly 20 stone (127kg or 280lbs) now having been a manageable 16 stone (101kg or 224lbs. Ironically, before I was diagnosed, I was the fittest I've been in my adult life, but the symptoms became too much to ignore. I'm 61 year old male with B12 deficiency, for which, much to chagrin all of my doctors', past and present, I self medicate by injection of 1mg per month. Over the past two years I've developed mild depression (maybe pandemic-related?) and most persistently, an almost continuous brain fog. I've repeatedly asked my doctor to investigate this and very reluctantly, angrily even, he referred me for a brain scan to investigate, at my suggestion, MS. The results though suggest that there is evidence of a previous bleed, which isn't good, but if it were an ongoing stroke, then I'm sure they'd've called me back more promptly for a follow up scan and treatment. As it is, I return at the end of this month for another, I assume, more focussed brain scan. I also suspect that the bleed may date back two years when I had a tympanoplasty to close a hole in my ear drum.
I'm aware that I need to see the results of the scan first before tackling my doctor again about the brain fog, but does my Levothryoxine dosage of 150mcg/day X 3 days a week and 125mcg/day X 4 days a week sound about right? Should I look into T3 testing too and if so, what may be the virtue of that? Perhaps a question for the Persistent Anaemia group, but is there any relationship between thyroid function and B12 deficiency? I've suspected B12 deficiency related neuropathy as a cause of the brain fog as it feels very similar to the brain fog I suffered prior to B12 deficiency diagnosis. I take daily folate too. I also have a gluten free diet after being diagnosed with Food-Related Irritable Bowel Syndrome some years ago. I progressively removed foods from my diet until wheat and wheat gluten was identified as the culprit. As far as I know, I'm not coeliac. don't post very often as having had the radioiodine treatment for hyperthyroidism, I thought that my position was now permanent and I only needed the annual thyroid function tests my doctor (new this year) takes every year.

Finally, I feel that I should take a comprehensive set of private blood tests (with commentary) as a second opinion to my annual thyroid function testing and other throw away diagnoses from my doctor - he blamed the brain fog on depression and has been studiously quiet since revealing the result of the brain scan I insisted on having. I knew something was wrong with my head. I'm fairly clear where to get these tests, but what should I have tested? Incidentally, I have COVID at the moment and am aware that I should defer such testing for a while and until after I'm clear of C19.
