i have hashi's too and my most recent anti-TPO was 465, yet my TSH was 5.12. previous TSH levels have been in the 7's (in march) and in the 2's (in april). i'm not on anything right now but i'm going to press my endocrinologist for some treatment options when i see him next. from what i've read, i probably would benefit from a low dose of hormones. i also have no known symptoms of hypothyroidism to date. i DO have slow digestion issues (gastroparesis), though, which we're still trying to determine the cause of... so those might be related.
smb74 - hypo and hashis isnt that bad... (like it could be worse...), i dont know about your dosage - its difficult to tell coz everyone is different. dont worry if its too little - you can always work your way up - i reckon its better to work your way up than down! hope it works for you!
micaela27 - if your tsh is 5 i would ask for treatment! (i felt really crappy when mine was 1.8!). im not sure what gastroparesis is, but i was majorly constipated when i was hypo (like all i ate was roughage - 6 big cobs of corn a day plus rice bran and veggies!!), so maybe the gastroparesis could be related to the hypo. digestions certainly seems to be affected by thyroid levels!
my wife also has gastroparesis, as well as possible touch of hashimoto's. her anti-TPO antibodies were mildly elevated, but nowhere near 400's. however, they were apparently high enough to cause our infant (who she was carrying when gastroparesis symptoms started) to be born with congenital hypothyroidism. her thyroid function labwork has otherwise been normalish, but ever since we conceived our last child, she has had symptoms of gastroparesis, even since delivery. we may try the gastric pacemaker soon, although it is terribly expensive.
