Why does the thyroid produce T3?
As we all know, the thyroid produces T4 and T3. Given that the body converts T4 to T3, why does the thyroid produce T3? I once asked Prof Weetman this - he admitted he didn't know.

Can someone clever please help with this Blood test of yesterday? It was slightly higher 3 months ago but my TSH was higher also so I didn’t worry too much. So now Levothyroxine has been increased and I’m over corrected at TSH of 0.25 and Free T4 of 30. Was hoping that my previous TSH of 5.4 was responsible

I’m currently taking levothyroxine - 75 4 days a week and 100 3 days a week. Latest test results are T4 21.7 and TSH 1.92. Time to change my dosage or continue? I can’t get an appointment with anyone sensible now for over a week

Update on Endo and WLAMS
Re the Endo who was determined to take away my T3 whilst all I wanted was a blood test to include T3. After an exchange of letters, he phoned this morning. He had back pedalled so far he was out of site. He agreed T3 was vital, he agreed testing the full TSH, T4 and T3 were needed to make a positive

Can a change in batch be the reason my thyroid hormones have dropped so low?
I was on 100mcg a day at the end of November and my results were TSH - 0.011 (0.27-4.2) Free T4 - 21.6 (12-22) (96%) Free T3 - 5.8 (3.1-6.8) ((73%) I thought the T4 was a bit high and I was having some mild palpitations so I reduced to 4 Days 75 mcg and 3 days 100mcg. After 7 weeks I retested

Hypothyroid for 30 years
I've been Hypothyroid for 30 years, I take Levothyroxine 100μg during the night - to keep it separate from all the other meds I have for other conditions. I follow the advice that certain foods are 'not helpful' for a hyperthyroid condition (Brussel sprouts, Cauliflower - which I have very occasionally

private testing
hi all, I hope you’re well. I’d like to ask about the finger prick home tests that Blue Horizon offers. How are they able to check all of the below markers with such a small blood sample? I’m aware that containers are super small and they claim to be testing a lot: Inclusions: TSH, FT4, FT3, TT4

Another 8 weeks on. Advice, please
Hi everyone. Background: I was diagnosed with hypothyroidism some years ago, but only discovered last November (2023), thanks to the forum, that I have an atrophied thyroid. Also, upped my dose of Levothyroxine in early October from 100 mcg Levothyroxine 3 times a week and 125 4 times a week plus 10mcg

Tired all the time
Lately I feel tired all the time, from when I wake up to when I go to bed in the evening, despite the fact that I sleep more than 8 hours per night. I take a lot of supplements (calcium, D3, folate, complex B, magnesium glycinate, heme iron),
the only value that was low was ferritin
but I do take

Can Someone be in the normal TSH range but still be suffering from Hypothyroidism
My daughter has been suffering multiple symptoms, reoccurring urology issues, aches and pains, IBS to name but a few. Her GP’s have only ever tested for TSH which has always been in the middle of the range. As I have autoimmune hypothyroidism as well as an autoimmune blood disorder should they be

Asking to learn
Sorry for all the questions but you all have been so helpful. If your hypothyroidism is secondary shouldn't your medication be based on your free levels and not your tsh?

Secondary hypothyroidism
Has anyone had problems with central hypothyroidism and their tsh going to zero. Doctor refusing to raise levothyroxine because it will suppress tsh to much but my free t4 really needs a raise. Does a low tsh really cause afib and osteoarthritis or is this false.

Medichecks results, please advise
Hi Everyone, posting my 1st ever private blood tests. Please can anyone comment, I'm quite new to this. The results came with a Dr's overview, so I'll be taking Vit D supplements but the other results appeared 'normal'. What do you think? And do the autoimmunity antibodies indicate Hashimoto's or am

Test results show no inflammation
I posted here 4 months ago and got my blood tested by the GP. There are no inflammatory markers in my blood, but I have a constant sore throat and dry eyes which are also beginning to suffer with high pressure. I am paying privately to have my eyes checked out by a specialist, but I just wanted to check
