Hi I am new to forum. I was told I have hypothyroid in 2012 but after getting my latest results I think I am hyperthyroid after being on such a low dose of thyroxine which is 50mcg. I don't have hyperthyroid symptoms though and I don't know why?
Thank you
TSH 0.02 (0.2 - 4.2)
Free T4 25.3 (12 - 22)
Free T3 6.9 (3.1 - 6.8)
Do you have Hashimotos ?
That was going to be my question, too! Do you have Hashi's?
Do you have your results from when you were diagnosed? Have you been on 50 mcg since 2012?
Yes I have Hashimotos. No I have had my dose moved about so many times I don't know what to do.
Results when first diagnosed:
TSH 44 (0.2 - 4.2)
Free T4 10.6 (12 - 22)
OK, so if you have Hashi's, it could very well be that when you did that test, you were at the tail end of a Hashi's 'hyper' swing.
Meant to ask, have you had other tests on 50 mcg that were in the normal range? If so, it can't possibly be that your dose of 50 has suddenly pushed you over-range.
When you have Hashi's, the antibodies attack the gland and destroy it. And the damaged cells release all their hormone into the blood, causing your levels to go temporarily high. But, it is only temporary. They will go down again. And, this is probably why your dose has been changed up and down so often.
Doctors just don't seem to understand about Hashi's swings and how they work. But, to avoid them, it's best to keep your TSH suppressed. Less gland activity means less antibody activity. Your levels wouldn't swing quite so much. Are you on a gluten-free diet and taking selenium?
Thanks no I have no other tests with me on 50mcg. At the time I was on this dose I was suspected of having Addison's disease so endo was reluctant to increase

Thanks I think I have hashimotos and not graves due to high TPO and TG antibodies
I just didn't understand why until I saw grey goose's answer I had high thyroid levels with a low dose and when first diagnosed I had high TSH and below range T4
Well, as long as you feel ok. Your results are only a little above range right now. Try going gluten free because gluten can irritate the gut.
Thanks no I am not feeling ok at all.
Sorry, when you said you had no hyper symptoms with those results I thought you meant it was all good except being a little over range results. There is another thought that you have all this hormone but it really isn't entering the cells and with T3, there can be way too much and the receptors shut down for that reason. So you are not over medicated, you are under using.
Often that is due to high cortisol or very low ferritin. So the doctor who thought you had Addison's (too low cortisol), did he do a cortisol test. Low ferritin means you are using up iron for some reason.
Kyra, it gets a little complicated when you've been hypothyroid for a long time without addressing the other issues....and often they don't address other issues.
My symptoms are in another post. I have optimal ferritin but low MCV so I am taking iron tablets for that. And I had high cortisol found about 2 years ago.
Ferritin 78 (15 - 150)
MCV 76.2 (80 - 98)
From Dr. Kaslow
The MCV is decreased in:
Copper deficiency
Low stomach acid (Hypochlorhydria).
Vitamin C insufficiency.
Vitamin B6 deficiency.
Rheumatoid arthritis.
Toxic effects of lead and other toxic elements.
Hereditary (thalassemias, sideroblastic)
Iron deficiency (blood loss, parasites, poor intake, low stomach acid, etc)
After a splenectomy
Hemolytic anemia
* Note: Because anemia due to folic acid and B12 anemia are difficult to differentiate without more sophisticated tests, any supplementation of B12 should always be accompanied by Folic Acid as well, and vice versa. It has been said that an iron:copper ratio <1 on a hair-mineral analysis is indicative of both folic acid and B12 need. Folic acid and B12 should be considered in all cases of nerve inflammation, nerve degeneration blood sugar problems, nerve irritation and vegetarian diets. Often with either folic acid or B12 deficiency, there is low stomach acid. It is important to treat all of these deficiencies rapidly and effectively to prevent permanent damage.
