thyriod nodules/iodine deficiency question
Back in January this year I read an article on an Iodine deficiency test whereby you paint on a tincture of iodine onto your skin and observe how long it takes to disappear. On two consecutive days my patches were gone with 5 hours and according to the article “you are severely iodine deficient if it is absorbed within 8 hours."
Then I came across an article which made me sceptical as it conflicted with the iodine patch test article.
After reading this I put the whole Iodine issue out of my mind until a routine ultrasound(17/2/2006) of the neck found a “a solitary 1.3cm nodule of mixed echogenicity in the upper pole of the left lobe, but no other abnormality”. My doc thought it was of no consequence because my thyroid blood tests were normal –TSH 2.85.
( but in 12/12/2005 TSH slightly high TSH -4.25, FREET4 12.8, FREET3- 4.6) .
Just recently I brought up the nodule issue again with my doc and at my suggestion he OK’d another follow up ultrasound (10/10/2006) which showed “unchanged 1.3cm nodule in left lobe since Feb 2006 but two small nodules on right(3 x2 x 1mm and 6x6.5x5mm) ,which were not previously noted.”
My doc’s reaction –“you should be happy. You are now multinodular and this is very rarely malignant, and as your two most recent blood tests were normal no need for any further testing 14/6/2006 TSH 1.79 FREE T4- 13 31/8/2006 TSH 2.05 FREE4 -16.”
But why am I getting Nodules? - "Nearly everybody at your age ( 57 yo) gets nodules" was his response. He said I could have a nuclear medicine test but it was not warranted.
So I remembered the Iodine deficiency test and did the patch test again, and again gone in 6 hours, so I approached an alternative type doc about a 24 hour iodine urine test.
Unfortunately not done in here Australia but offered a spot random iodine test which I had done and just got back showing a reading of
Iodine 63 ug/l
( which is considered mild deficiency by the ICCIDD.)
When I took this back to my regular doc he admitted he didn’t know what the test was or meant.
Since February I’ve lost 35kg ,admittedly I was overweight at 130kg, but 20-25 kg peeled of fairly quickly and from my point of view, unexplained, but I had just been diagnosed with gastrititis, duodenitis along with high anxiety, so I brought my bad eating and drinking habits to a halt(this probably explained some of the quick weight loss). The last 3 months have seen me lose 7kg ,I’m now 95kg( 6’3’’ TALL) and gastro specialist believes I‘ll probably start to plateau.
Even though I’ve had a million tests everything keeps coming back normal (except pac’s and pvc’s and anxiety have crept back into my life) but I still believe something is not right and something is being overlooked,especially in light of the wait loss and thyriod nodules and /or iodine situation.
I read somewhere that thyriod nodules can sometimes mimic hypo/hyperthyriodism,which could possibly explain some of the maladies I am experiencing(eg weight loss, food sensitivities and intolerances-confirmed by IgG BLOOD TEST,hyperpermability confirmed by mannitol/lactulose permeability test,arrythmias-pac's,pvc,s confirmed by 24 holter monitor to name a few).
Most docs suggest these are all separate issues,but I believe there probably is a "root cause" and that the thyriod nodules and/or iodine deficiency might be a major player but until recently I did not know anything about the subject and have been just "sleuthing" the internet trying to come up with some answers.
But there are so many conflicting theories about normal and abnormal levels of TSH,T3,T4, the cause and effects of nodules,how important is iodine,and the reliability of the iodine patch test(which was cornfirmed by the urine test -- but the patch test indicated severe deficiency whereas the blood test indicated mild ) false negatives,false positives,when you do and don't need medication, no surgery,partial removal,total removal,the list goes on and on.
So who do you believe and who do you trust?Do I now leave it alone or do I do further testing ?
Is there a resident Doctor or some experienced person on this forum that could give some advice as to how I tackle this problem and what tests should be done and/or what supplementation would be appropriate .
Sorry for the long email but would appreciate any comments you are allowed to make on my situation especially the thyroid-iodine predicament and point me in any direction you might consider appropriate.
Yours Thankfully Vickersave
