link11 Yet another TSH obsessed doctor who knows diddly squat about treating hypothyroidism and is keeping his patients ill. There was absolutely no need to reduce your dose of Levo. Your FT4 is within range and your FT3 is less than half way through it's range.
From ThyroidUK's main website > Hypothyroidism > Treatment Options:
"According to the BMA's booklet, "Understanding Thyroid Disorders", many people do not feel well unless their levels are at the bottom of the TSH range or below and at the top of the FT4 range or a little above.
Dr Toft states in Pulse Magazine, "The appropriate dose of levothyroxine is that which restores euthyroidism and serum TSH to the lower part of the reference range - 0.2-0.5mU/l.
In this case, free thyroxine is likely to be in the upper part of its reference range or even slightly elevated – 18-22pmol/l. Most patients will feel well in that circumstance.
But some need a higher dose of levothyroxine to suppress serum TSH and then the serum-free T4 concentration will be elevated at around 24-28pmol/l.
This 'exogenous subclinical hyperthyroidism' is not dangerous as long as serum T3 is unequivocally normal – that is, serum total around T3 1.7nmol/l (reference range 1.0-2.2nmol/l)." "
Dr Toft is past president of The British Thyroid Association and leading endocrinologist.
You can obtain a copy of the article by emailing firstname.lastname@example.org , print it off, highlight question 6 to show to your GP then ask for your Levo to be increased back to where it was and retest 6-8 weeks later to check your levels.
Are you taking a B Complex alongside your methylcobalamin supplement, this is needed to balance all the B vitamins.
Was ferritin tested? This needs to be at least 70 for thyroid hormone to work, recommended level is half way through it's range.
