Thanks DKMA, I am only on 50mg, levels apparently back to normal, iron levels fine but still feel knackered. Going to try and get a referral to an endocrinologist as I got this info from a thyroid site
'Q. I am on thyroxine, but I still feel ill.
Why could this be?
A. Some people still have symptoms when they are on thyroxine. This can be due to many things. It can be that they are not on enough thyroxine for their needs. Before blood tests came into play, people were given more than 200mcg, although many doctors now don?t like to give more than 150mcg. Thyroxine should also be given according to weight, so the bigger you are, the more you should have. In reality, this does not happen. Each doctor seems to have his own ideas about the highest level he will allow his patient to be in the range. He then tells the patient that she cannot have any more thyroxine, even though the patient still has symptoms.
Another reason many people still feel ill on thyroxine is that they are not converting the thyroxine into T3 (tri-iodothyronine). This conversion takes place outside of the thyroid, mainly in the liver, so if the patient has some kind of problem with the liver or any of the other places where conversion takes place, then deficiency will occur. Certain vitamins, especially those of the B group and some minerals are also necessary to aid conversion, namely: iron, selenium, magnesium and zinc. If you are deficient in any of these then conversion will be less effective. If this is your problem, then you will need to supplement your T4 with T3, or take the natural form of thyroid hormone. Armour natural thyroid is an excellent alternative, which has not only T4, but T3, T2 and T1.
If you have adrenal insufficiency, this can also cause major problems for the receptor uptake of the T3. Some kind of adrenal support will be needed before the receptors can uptake properly. Many people have this problem in these stressful times; it can be caused by car accidents, major surgery, autoimmune disease attacking the adrenal glands and, of course, inadequately treated hypothyroidism.
Lastly, there seem to be a lot of people who just cannot tolerate the synthetic form of thyroxine and fare much better on the natural form which contains all four thyroid hormones.
If you are not receiving enough thyroid hormone or not getting the correct form of hormone into your body, then you will still have symptoms. '
Anyway on that note, off to bed, night all
