Underactive Thyroid

Hello guys!!!

I have had a underactive thyroid for many years now and been on thyroxine for around 15 yrs. I’m on 150mg. They treated me with depression at the beginning and that nearly sent me over the edge. I must admit I’ve struggled with tiredness and being able to relax. I have had my bloods done and the doctor says my bloods are fine. I did ask my doctor this time to check my liver function, bilirubin ALT-ALP and that came out ok. I’m a bit over weight but not that much. I am very hungry especially at night and noticed my testosterone levels have dropped and wonder is it because I have a underactive thyroid?? I sometimes can have lots of energy and running 100 miles an hour or can wake up feeling exhausted. Please can any one give me some advice, will be very appreciated.

Sorry is this message for me??? First time I’ve been on here, just getting to know how it works😀


Yes. Messages posted under your question - on what we call your 'thread' - are normally for you. :)


Thanks for that!!! Will have to go and see my doctors for my results, they never give them to you, they just say your counts are fine and if you want them you have to pay for them. So will go back and ask for a print out 😀

Are you in UK? You shouldn't have to pay for recent bloods results. It is your legal right to be given the results. Ask to speak to the practice manager. You should be able to access your results on line.

I am and thanks for your advice. I’m going this morning and will have a chat with the practice manager and try get my results on the net. Should of done this years ago. It’s good getting and seeing advice on this great service 😀


For full evaluation you ideally need TSH, FT4, FT3, TT4, TPO and TG antibodies, plus vitamin D, folate, ferritin and B12 tested

Post results and ranges for advice

See if you can get full thyroid and vitamin testing from GP. Unlikely to get FT3

Private tests are available


Medichecks Thyroid plus ultra vitamin or Blue Horizon Thyroid plus eleven are the most popular choice. DIY finger prick test or option to pay extra for private blood draw. Both companies often have money off offers.

All thyroid tests should be done as early as possible in morning and fasting and don't take Levo in the 24 hours prior to test, delay and take straight after. This gives highest TSH, lowest FT4 and most consistent results

Print this list of symptoms off, tick all that apply and take to GP


Vitamindtest.org.uk - £28 postal kit if only want vitamin D tested


Thanks for all this great advice. I love all the information. Will get on it and go back to see my doctor. Didn’t realise how much I need to do. I do however take a vitamin D spray, so should be sufficient on that I hope!!! Will let you know how I get on 😀
