Good Thyroid levels, terrible ferritin

[Guest guest]

OK...what shall I do now?

Had tests prior to starting my Cynomel from Mexico - which I am feeling good on.

I was expecting my T3 to be low but it was 5.1 (ref 2.6 - 5.7).

Like I say this was based on 100mg T4 only and I did not take any on the morning

of the test.

My T4 was 16.3

TSH 0.74.

BUT my ferritin is still really low (forgot to get levels) but GP phoned to tell

me.

Ive been on liquid iron for 3mths after getting nowhere with tablets. But it

seems the liquid iron isnt working.

So....anyone know whats going on? I need to double my iron daily.

Should I still continue with my reduced T4 (.75) and 25mg split in 2 daily???

Could the low ferritin affect my thyroid function even if the levels are good??

Just dont know whats going on. Im thinking continue as I am with the T3 and get

retested in January when I see the specialist?

Low iron, transferrin

saturation%, ferritin and B12 can affect thyroid uptake very much. Read just

some of the research and studies that have been done regarding low levels of

specific vitamins and minerals to show how low levels can stop the thyroid

hormone from being properly utilised at the cellular level:

Low iron/ferritin: Iron deficiency is shown to

significantly reduce T4 to T3 conversion, increase reverse T3 levels, and block

the thermogenic (metabolism boosting) properties of thyroid hormone (1-4).

Thus, iron deficiency, as indicated by an iron saturation below 25 or a

ferritin below 70, will result in diminished intracellular T3 levels.

Additionally, T4 should not be considered adequate thyroid replacement if iron

deficiency is present (1-4)).

You may find that your GP needs to try you on different forms of

elemental iron until one is found that you can properly absorb. Are you taking

high doses of vitamin C with the iron, i.e. 3/4000mgs daily?

Some people need to take iron three times daily, but the problem

is that you must never take iron and thyroid hormone within four hours of each

other. How have you been taking yours?

do you know what your copper level is? do you know what your zinc level is?

both these are needed for proper utilisation of iron ...as is magnesium.

i think these days it is recommedned to have a full set of iron tests done in

order to determine whether you need to supplement or not.

have you been tested for heliobacter? ...apparenty that can often be implicated

in low ferritin levels.

another thing is there is a *pay back* system regarding low iron status...i

forget exactly how it works but something along the lines of iron is returned to

the bone marrow first ...sometimes ferritin initially drops with supplementation

due to this *pay back* system.

too much iron is damaging (you rust from the inside!)

Hello Hayley

You need to ask the endocrinologist to test your levels of iron,

transferrin saturation%, ferritin, vitamin B12, vitamin D3, magnesium, folate,

copper and zinc, and when these results are returned, post them here on the

forum together with the reference range and we will be able to help with their interpretation.

Many doctors will tell you that you do not have a problem if such results

appear ANYWHERE within the reference range. They are not taught how to read

such results or taught about their association with low thyroid levels.

Hayley would you please make sure you erase most of all the previous message/s

before you click on reply. I have done it this time but it is very time

consuming.

Have listed everything ready for the 20th Jan. I will be in touch to let you

know how appointment goes.

Thanks again x
