I've recently had some blood tests done with BH as I have been struggling to lose weight for the past 2 years despite being more active than I've ever been & having a much improved diet . I had TSH tested with my doctor back in February and that came back high, but no T3 or 4 was tested.
I've had the results back and BH have said 'The Thyroid Stimulating Hormone (TSH) is elevated. If you are already taking a form of thyroxine, it is possible that that your dose is too low or that you have forgotten to take it on occasion. It may be that an increase in dose is in order – if adjusted it would be sensible to repeat thyroid function (TFT) testing in around 2 months' time. If you are not taking thyroxine, and this is the first time TSH has been noted to be high, it is possible that 'non-thyroidal illness' or other medication effects are the cause of the elevation. It may be that hypothyroidism (underactive thyroid gland) is about to develop. In these scenarios, it would be advisable to repeat thyroid function tests in 3 months' time. If this a repeat elevated TSH, it would be a good idea to consider checking thyroid antibodies if not previously tested. If antibody testing is positive, an annual check of TFT would be in order as your risk of developing thyroid disease would be higher than average. I would suggest undertaking this repeat test sooner if symptoms develop. The usual advice is to consider commencing thyroxine if TSH rises above 10 mU/L. Some authorities advise commencing thyroxine at lower TSH levels. '
I'm guessing that this is a standard response to these results but i am at a loss as to whether I should be on medication or if there is some other underlying issue causing me not to lose weight.
I have an appointment with my doctor next week to discuss the results but would really appreciate any advice on whether I'm 'barking up the wrong tree thinking it's thyroid related.
I've put the results below, any comments would be appreciated.
