Three years ago I got really unwell, and the doctors first suspension was that it could be my metabolism. I guess the blood tests where OK, and I went on to neuro, then rheuma and back and forth. My TSH, T3 and T4 are all very low almost too low when they check it and now another doctor thinks I have a minor stroma and I should have it checked out.
I fitt the symptoms of low metabolism, but what is going on if they are ALL low - I understand the principle behind the test, but not this? Thanks

If you can post your test results - along with their reference ranges that we need to interpret them, eg. TSH: 2.5 (0.27-4.20) - then members will be able to comment, at the moment just saying "low" doesn't really give us anything to go by.
Thanks - how kind. I will do so this evening 
If your taking steroids, TSH can be falsely low
For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested.
Very important to test vitamin D, folate, ferritin and B12 at least once year minimum
Low vitamin levels are extremely common, especially with autoimmune thyroid disease (Hashimoto’s or Ord’s thyroiditis) usually diagnosed by high thyroid antibodies
Autoimmune thyroid disease with goitre is Hashimoto’s
Autoimmune thyroid disease without goitre is Ord’s thyroiditis.
Both are autoimmune and generally called Hashimoto’s.
In U.K. medics never call it Hashimoto’s, just autoimmune thyroid disease (and they usually ignore the autoimmune aspect)
Recommended on here that all thyroid blood tests early morning, ideally before 9am
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins

If you have one autoimmune disease, it makes others more likely
About 90% of all primary hypothyroidism in Uk is due to Hashimoto’s.

Thank you I have been on steroids from mid 2019-end 2020, så that would explain a lot. The TSH was low already before that but just above normal range. They have only ones been taken together and that was during hospitalisation, when I was put on high prednisolon due too asthma (and covid). T3 are not that low I see now. All the vitamins and minerals are OK. I guess I ask to have them all taken at the same time.
Yes you need to take TSH /fT4 and fT3 together again now to see what your thyroid function is ......Thyroid results taken during 'hospitalisation' are not reliable for diagnosing thyroid issues . this is because acute /severe illness causes alterations in TSH /fT4 /fT3 levels that should return to 'normal' when you are recovered from the illness.
Below is a graph of what happens to TSH /fT4 /T3 levels when a person with a healthy thyroid is severely ill from 'something else'.
So your below range fT3 in hospital may not be not a true representation of what your fT3 level is 'normally'.. it may have been so low because you were very ill.
Thank you so much for the chart - it does explain a lot of my results...
Could it be just the low ferritin? 
Could thyroid be causing the issues ?
Could This Be Thyroid? 
Could it be possible?
What could it be?
