hi- i went to a good thyroid doctor yesterday and, via ultrasound, learned that my thyroid is exceptionally small: about 3/10 the normal volume, with the wrong kind of blood flow and texture. the doctor diagnosed me with hashimoto's even without seeing any antibody or other tests. she said she could tell from looking at the ultrasound that the hashi's didn't start 2 or even 10 years ago, but longer. (indeed, i've had terrible symptoms since i was a child, but the hypothyroidism went undiagnosed until about 4 years ago because my TSH was always 'normal.')
i was wondering about the implications of all of this. i don't love the idea of learning that my thyroid has been reduced to a small, useless piece of junk at this point, but it also doesn't really make a difference in terms of treatment (i've been on thyroid meds for about 4 years now; am still struggling to optimize and be comfortable). my TSH has been totally suppressed for a few years. i guess i'm just wondering if anyone knows anything about this tiny thyroid business. should i worry that NDT caused the attack to increase? does it even matter anymore since the auto-immune damage has been done? (thyroids don't come back, right?) could the TSH suppression have caused the thyroid to atrophy? is 45 a bit young for this to have happened? (i keep reading that this happens 'in the elderly' or at 'the end stage of the disease.') in some ways, maybe this makes things easier: the doctor said that when the thyroid tissue dies b/c of the auto-immune attack, it releases thyroid hormones into the body (making for either euthyroid or hyper states), and that it might be easier to find a comfortable / stable medication dose once these changes aren't happening.
any info or thoughts or similar experiences appreciated!
