I am not sure that this is further information! It is just the stuff that docs have been taught is true.

I feel so bad for the woman who is struggling to help herself, b/c this is how I was.

this article reminds me that iodine/iodide and dose are very important.

Seaweed Goiter, or How I Grew My Thyroid While Ingesting Large Amounts Kelp

50 Y/O F had a small nodule 6 years ago which was biopsied and told it was benign. She refused thyroid hormone suppression, and when it continued to grow, she even refused surgery. She treated the goiter nodule with her own home plan as suggested by the internet. If you have thyroid problems, it stated, take iodine supplements. She did that for the next 5 years as the nodular goiter continued to grow! She had multiple biopsies and she claimed that biopsies caused the goiter to grew. She finally saw me last week. She is euthyroid with a large bilateral goiter with her trachea moved to one side to make room for the larger right lobe. The US showed another big nodule on the other lobe. Now she needs to stop the iodine supplements, and Kelp, and have yet another biopsy of the new nodule. What did she learn?Iodine is not only not good for goiters in the USA, because we have enough iodine in our diet, but it can be down right harmful.Do Not Take Iodine Supplements without being informed of the dangers if you have a goiter, Hashimoto's thyroiditis, or nodules.See you next time on Thyroid Rounds at Santa Thyroid Center,Good Day,Dr.G.

Someone on the natural Thyroid hormone group said that this Endo was the one that went after Shomon to try to put a stop to her "message". He's an idiot from what I can see. If you read the first blog it should have sickened you to see that he hoped that the woman with the goiter had thyroid cancer so he could force her to take her thyroid out. What a sick way to look at treatment. Why is it so obvious to me that she had goiter so give her iodine?

*shaking head*

Actually, there are hundreds of published studies showing iodine can

trigger and exacerbate Hashimoto's, in addition to the anectodal

stories and posts we've all seen of people who just cannot tolerated

it. No true expert or scientist will ever say that any medicine OR

natural substance is ALWAYS without adverse effects for everybody.

Anyone saying that is clearly ignoring overwhelming evidence to the

contrary.

Note here that Japan has one of the highest incidences of Hashi's:

and the prevalence of subclinical hypothyroidism in the coastal

regions of Japan. J Clin Endocrinol Metab 78:393-397, 1994.

Autoimmune thyroiditis has also been linked with iodine intake. For

example, the highest prevalence of this condition is in countries with

the greatest intake of iodine (i.e., the U.S. and Japan).16 However,

iodine supplementation in areas where iodine intake is low also

increases the number of patients who test positive for thyroid

antibodies—up to 40% of patients within five years of the initiation

of supplementation.17 In areas with sufficient iodine, increased

iodine intake can decrease thyroid hormone secretion in the presence

or absence of thyroid antibodies. This suggests that the underlying

mechanism in these cases is inhibition of hormone biosynthesis rather

than thyroid autoimmunity.18,19

found in 78.3 % of group 1 (18 out of 23 patients), which is higher

than the 45.5% from group 2 (10 out of 22 patients). In group 1, mean

serum fT4 level (0.80 +/- 0.27 ng/dL at the baseline, 0.98 +/- 0.21

ng/dL after 3 months) and the TSH level (37.95 +/- 81.76 micro IU/mL

at the baseline, 25.66 +/- 70.79 micro IU/mL after 3 months) changed

As I said, there are hundreds of studies, these are just indicative of

the preponderance of evidence linking iodine to Hashi's.

But I realize that many people who profess to be experts prefer to

ignore all of this and take the unscientific one-size-fits-all

approach, and shrug off the studies by saying that they're probably

all funded by big pharm, even though they have no proof.

There is enough evidence and personal stories out there to warrant

exercising reasonable caution with iodine, especially if one already

has Hashi's and is positive for TSI.

I realize I am in the minority here and have already been banned from

another group for daring to caution a person with Hashi's, even though

I make it very clear that iodine can be very helpful for many people

Hi ,

So it looks like what they are saying is that they suspect Hashimoto's

can be caused by iodine intake in people who didn't previously have it.

So you have any links for any more studies that show that?

Thanks,

non-restriction group (group 2). The thyroid-related hormones and the

urinary excretion of iodine were measured at the baseline state and

after 3 months. After 3 months, a recovery to the euthyroid state was

found in 78.3 % of group 1 (18 out of 23 patients), which is higher

than the 45.5% from group 2 (10 out of 22 patients). In group 1, mean

serum fT4 level (0.80 +/- 0.27 ng/dL at the baseline, 0.98 +/- 0.21

ng/dL after 3 months) and the TSH level (37.95 +/- 81.76 micro IU/mL

at the baseline, 25.66 +/- 70.79 micro IU/mL after 3 months) changed

significantly during this period (p < 0.05). In group 2, the mean

serum fT4 level decreased (0.98 +/- 0.17 ng/dL at baseline, 0.92 +/-

0.28 ng/dL after 3 months, p < 0.05). In the iodine restriction group,

the urinary iodine excretion values were higher in the recovered

patients than in non-recovered patients (3.51 +/- 1.62 mg/L vs. 1.21

+/- 0.39 mg/ L, p=0.006) and the initial serum TSH values were lower

in the recovered patients than in the non-recovered patients (14.28

+/- 12.63 micro IU/mL vs. 123.14 +/- 156.51 micro IU/mL, p=0.005). In

conclusion, 78.3% of patients with hypothyroidism due to Hashimoto's

thyroiditis regained an euthyroid state iodine restriction alone. Both

a low initial serum TSH and a high initial urinary iodine

concentration can be predictable factors for a recovery from

hypothyroidism due to Hashimoto's thyroiditis after restricting their

iodine intake.

As I said, there are hundreds of studies, these are just indicative of

the preponderance of evidence linking iodine to Hashi's.

But I realize that many people who profess to be experts prefer to

ignore all of this and take the unscientific one-size-fits-all

approach, and shrug off the studies by saying that they're probably

all funded by big pharm, even though they have no proof.

There is enough evidence and personal stories out there to warrant

exercising reasonable caution with iodine, especially if one already

has Hashi's and is positive for TSI.

I realize I am in the minority here and have already been banned from

another group for daring to caution a person with Hashi's, even though

I make it very clear that iodine can be very helpful for many people

and have gotten many emails thanking me for the info.

I have faith that most people can make an intelligent decision one way

or another--IF they are given info on both sides. Censoring one side

of it does nobody any favors and presumes that people are too stupid

to make an intelligent decision.

No it is more than that. She has done other things off line with me. The discussion of Hashi's isn't an issue with me it is presentation that is. This is not the first group she has been banned from. There are many others.

It isn't anyone's business here what happened.

Re: Re: Iodine + goiter, Hashimoto's, nodules

Hi ,

So it looks like what they are saying is that they suspect Hashimoto's can be caused by iodine intake in people who didn't previously have it.

So you have any links for any more studies that show that?

Thanks,

iodine supplementation in areas where iodine intake is low also

increases the number of patients who test positive for thyroid

antibodies—up to 40% of patients within five years of the initiation

iodine intake can decrease thyroid hormone secretion in the presence

mechanism in these cases is inhibition of hormone biosynthesis rather

than thyroid autoimmunity.18,19

less than 100 micro g/day) and the other group was an iodine intake

non-restriction group (group 2). The thyroid-related hormones and the

In the interest of

providing full and scientific information, I think 's email caution was

spot on. I'm not sure how that

constitutes " stirring the pot " unless there were goings on that were

not on the list. Certainly, if one

is going to take iodine, given the research, it is important to keep an eye out

for Hashi's. I have Hashi's and am

seriously considering trying iodine.

Before I do, however, I want to see all the research. That's why I joined this list. Anecdotal evidence, for me, has little

relevance.
