If you are not on thyroid medication then the very low TSH may indicate a hyper state. In which case you must get an FT3 to confirm or deny. It's possible you may have T3-toxicosis where FT4 can be normal, TSH low, with a high FT3. The symptoms you describe are typical of a hyper state
What is your TSH, T4 and T3? sorry I see you have posted the results above. Your TSH is low (suppressed) but your T4 also seems low. I really need to know what your T3 and antibodies are to get a better picture. Are you taking any medication or supplements?
As my GP ignored my symptoms I got tested by myself but adding ft3 and antibodies would have costed so much as I also got gastro panel test which costs loads.
Trying to reach my GP to see if they would do the other tests.
I think my ft3 could be quite normal too as I am slowly getting less symptomatic, worst period was on December. And I have understood TSH normalises the last? I have had hypo phase in my past with borderline high TPOab.
Not on any medication and get B12,B1,B6 injections and take vit D and magnesium.
Have tried iodine here and there ,only 20-40 mcg , it making me feel terrible.
That could be causing you to feel ill. I would not take it again if I was you and then do another blood test to see what your levels are. I noticed you have had B12 injections so you can get symptoms from having low B12. I am not an expert but I have been on a lot of sites in the USA and here and have gained some knowledge. Hopefully other members who know a lot more than me will give you some advice. I just edited my post because I noticed you had changed yours.
Yeah I do too think iodine could be the bad thing and in my past I have had to avoid it with all costs but then I end up hypo with high thyroglobulin and low urine iodine.
During past year I have eaten food with added iodine ie oatmeal puddings, oat milk/cream and used a bit iodised salt.
Yes low B12 cause me symptoms but this is different symptoms with awful heart rate and other classic hyper symptoms.
