I appreciate any help anyone can offer me on this. I'll try to be succint!
I think I have suffered with mild hypothyroidism since I was a teenager. I am 33 now and tick a large number of the typical symptoms (although not in an extreme form) and so I eventually asked my GP for a blood test about 5 years ago to investigate. At that time my TSH result was 4.6 and I was told this was normal so I accepted it and just carried on coping with the symptoms. Since having my little boy 2 years ago, of course, the fatigue has worsened considerably (through running around after a toddler!) along with other symptoms such as problems sleeping and a complete inability (no matter what I tried) to produce enough breastmilk to breastfeed him when he was born. I am, thankfully, 4 months pregnant with our second child now but it took us about 8 months to conceive so I was starting to get concerned again that an underactive thyroid might be to blame. My GP ran a full suite of blood tests when I was about 10 weeks pregnant but would only test for TSH not T4, T3, antibodies etc despite me asking. My TSH level was 4.2 miu/L (ref. range 0.2-6). I take a pre-natal vitamin so my folate levels are very high but my vitamin B12 is 399 ng/L (ref. range 180-910) and my ferritin level was 34ng/ml (ref. range 10-291) so they seem quite low and could possibly account for some of the symptoms? I have also read that low ferritin might be linked to poor T3/T4 conversion? I tried to get my doctor to investigate further but he just kept saying my result is 'normal' and that no-one would diagnose or medicate me at this TSH level and that medicating could be dangerous? Is this true? Could anyone offer any advice on this at all - particularly with regard to this TSH level in pregnancy as I have worried myself reading that TSH should be lower than 3 during pregnancy and ideally around 2 otherwise there is increased risk of miscarriage etc? I think I will order a fingerprick test from either medichecks or bluehorizon if people recommend them as at least I can try and find out the T3/T4 levels and antibodies etc. I'm just unsure of their accuracy as they are so expensive! Also, I live in the North West (Cheshire) so if anybody could recommend an endocrinologist I would be most grateful. I can access private healthcare through my job so depending on my policy I may have the option of pursuing this privately. I just want to make sure I have a healthy a pregnancy as possible so I am willing to do anything to try and get it sorted if it is a problem. I just don't know if my TSH really is fine and 'normal' or if I'm just being fobbed off if the doctor is blindly following NHS guidelines?
Many thanks for any advice anyone can offer (sorry I tried to be succinct!)
