The economic impact of undiagnosed, untreated or undertreated hypothyroidism is therefore not inconsequential, especially with regard to costs associated with maternal and congenital hypothyroidism [ 1415 ], or with hypothyroid patients having comorbid conditions such as diabetes mellitus [ 16 ].

Another environmental toxin not mentioned which harms the thyroid is mold.

Duplicate post. However, this distinction is not clear-cut since thyroid size in hypothyroidism shows a normal distribution, with cases of thyroid atrophy or goitre representing extremes within this distribution [ 43 ].

The reasons for the observed rapid increase still are not fully understood, but evidence suggests that overdiagnosis, with the advancement in detection methods and screening policies, is not the sole driver of the substantial increase of the incidence.

Finally, two more common household toxins that disrupt thyroid function are the antibacterial chemical triclosan, found in products such as liquid hand soap, and Cases, used in non-stick cookware and stain-resistant fabrics. Of patients who are treated, up to gypothyroidism are not receiving adequate treatment [ 1213 ].
