Most labs are using (0.8-2.0) Free T4 range and (2.3-4.2). Free T3 range having these normal but elevated TSH points to sub clinical hypothyroidism
The higher amounts of fluoride and chloride compounds [such as perchlorate, sometimes present in drinking water], are able to impair thyroid function by displacing dietary iodine [these all sub-group of halogens, with fluorine having highest activity, and iodine the least active]. As a result, the people are becoming ‘iodine deficient’, even if they are getting enough iodine in their diet.
Such people show DECREASED radioactive iodine uptake test with moderate thyroid enlargement often present.
The summary of most recent article about soy consumption, shows that :
“in individuals with compromised thyroid function and/or whose iodine intake is marginal soy foods may increase risk of developing clinical hypothyroidism. Therefore, it is important for soy food consumers to make sure their intake of iodine is adequate.” [PMID: 16571087 [PubMed - indexed for MEDLINE]
‘Effects of soy protein and soybean isoflavones on thyroid function in healthy adults and hypothyroid patients: a review of the relevant literature’.
By Messina M, Redmond G. Department of Nutrition, School of Public Health, Loma Linda University, California, USA. [email protected].
Unless diffuse or nodular changes in thyroid are present, it can return to normal function in most cases, after number or amount of ‘inhibiting factors’ are reduced.
For your particular case two next diagnostic steps can be recommended:
-the RAI scan to determine ability of thyroid to take up iodine;
- the ultrasound of the thyroid to check its structure.
This would eliminate most of irrelevant “educated guesses” and would help to develop best treatment strategy [or would add more questions to research and answer].
Sorry for long boring reply. Best of luck!!
