Abnormal TSH/T4 readings

[Sparkle1982]

I wonder if someone can help. I was diagnosed with an overactive thyroid shortly after having my daughter in 2010. I was started on Carbumazole 10mg and referred to Endocrinologist. By the time i got to see him my TSH was 74.0 and i was commenced on Thyroxine. I have had a rocky path with getting my TSH to stabilsr but have had four years of being on 125mg daily. All of a sudden my TSH has rose to 6.0 and free t4 to 25.5 and i have all the symptoms of being hypothyroid. From my understanding this is not normal and with a high TSH you would normally have a low free t4. Can anyone give any advice on what thia means. Im seeing GP next week to find out what to do

Did anybody bother to test your antibodies? Sounds as if you have Hashi's. All sorts of strange things can happen with Hashi's.

Not that i am aware of. I will double check when i see the GP next week

If they haven't been done, then insist that you want your TPO antibodies tested.

For full Thyroid evaluation you need TSH, FT4, FT3 plus TPO and TG thyroid antibodies and also very important to test vitamin D, folate, ferritin and B12

Ask GP to test both TPO and TG thyroid antibodies plus all vitamins

Private tests are available. Thousands on here forced to do this as NHS often refuses to test FT3 or antibodies or vitamins

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 ideally be done as early as possible in morning and fasting. When on Levothyroxine, take last dose 24 hours prior to test, and take next dose straight after test. This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, GP will be unaware)

If antibodies are high this is Hashimoto's, (also known by medics here in UK more commonly as autoimmune thyroid disease).

Hashimoto's often starts with hyper phase and is frequently misdiagnosed as Graves

About 90% of all hypothyroidism in Uk is due to Hashimoto's.

Low vitamins are especially common with Hashimoto's.

Food intolerances are very common too, especially gluten. So it's very important to get TPO and TG thyroid antibodies tested at least once .
