Does anyone know whether Hypothyroidism is always caused by Hashimoto's?
My last TSH reading done by GP was 5.75. I had a MediChecks test done which showed one set of antibodies (TGAb) as quite high (331) but TPO, which is the only one the NHS looks at, was fine.
I haven't had surgery or any other kind of thyroid treatment. Just wondering really if I can assume that it is definitely caused by Hashimoto's. When I look at the NHS symptoms list I don't get cold, don't have constipation, although I do have a lot of other problems on the list such as weakness, fatigue etc. etc.
Sorry this is a bit rambly - just wondering if I really need to do the gluten-free etc. Or even if it hypo can be caused by vitamin deficiences.
