Your page for
Euthyroid Sick Syndrome
Contains this statement:
"Treatment with thyroid hormone replacement is not appropriate. When the underlying disorder is treated, results of thyroid tests normalize."
Not totally accurate. When the cause is decreased peripheral conversion of T4 to T3, the thyroid tests will never normalize on their own. As you know, T3 is the active version of the hormone -- the one that reaches the cells to cause healthy metabolism. The only way the thyroid tests will normalize in this case is if the condition is treated with replacement of the missing T3. Without treatment, the patient will continue to suffer many symptoms of hypothyroidism including weight gain, difficulty losing weight, and cold intolerance, Moreover, untreated hypothyroidism has been associated with a gradual decrease in mental functioning.
