Extremely high tsh level over 400, has anyone else experienced this?

Posted , 7 users are following.

i was just diagnosed with hypothyroidism but my levels for tsh were extremely high and the dr was baffled. He prescribed me 75mcg levothyroxine and i have an ultrasound coming up as well.

tsh - 451.7

t4 free - .11

what could this mean? any help would be appreciated.

    could they have put the decimal point in the wrong place? Normal levels are .4 to 4.0. Looks like it was a typo to me. I think it would be impossible to have a level at 451.7. you probably should be retestested and I would certainly question your Dr. about the possibility of a typo. Even if it's actually 4.5, that's still high. Have you had your t-3 and t-4 tested too?

    i believe you. i don't know if mine has ever been that high but I have reached triple digits. from my experience when it gets that high the symptoms only increase marginally. in other words it's not a one-to-one correlation between symptoms and TSH numbers. so even though your TSH numbers are increasing your symptoms could be increasing at a slower rate or just plateau off. How bad can a human feel? When is bad enough as bad as it gets? At some point you reach your symptomatic rock bottom and you can't get any lower. So the symptoms of TSH 600 could be the same as your symptoms at TSH 60... not that either of those are good.

    It's been a few weeks since your post and I do hope you are feeling better and have gotten your numbers lowered down to a more liveable number. I would love to hear how you are feeling now.

    i was looking into info about this issue and found your post

    i was diagnosed with hashimoto on june first this year with TSH 466!!!!!! My doctor asked me to start a diet (no sugar, moderate gluten more fruits and vegetables) and wait 4 months to see if the numbers go down I am afraid to wait 4 months to retest, i believe he should prescribe medication for my condition

    the thing is I do not eat sugar, i do not like sweets! i am eating gluten free bread and and I am literally lost
