  • Hypothyroidism is frequently observed in the elderly with an increasing trend with age. Patients with hypothyroidism who become pregnant should have their levothyroxine dosage immediately increased to nine doses weekly.

  • This has resulted in subclinical hyperthyroidism being diagnosed with much greater precision, irrespective of the population being studied or the method used.

Accessed 10 April Indeed, frail patients are more vulnerable to drug side effects for several reasons, and the prescription of l -T4 should be carefully balanced with the risk of overtreatment e. Overall, these data show how the aging process is characterized by a downregulation of the hypothalamus-pituitary-thyroid-peripheral-tissues axis, although it is yet to be established whether these changes reflect an adaptive mechanism to reduced metabolic functions or instead, represent a protective mechanism to preserve the body from excessive catabolism. Data sharing is not applicable to this article as no datasets were generate or analysed during the current study.

Finally, the circulating TSH variability, besides being a consequence of the aging process, could be the expression of actual thyroid pathology, especially in the case of positive TPOAb and TgAb titers. However, it is still a matter of debate whether the reduced thyroid function in the elderly as a result of either reduced pituitary gland secretion or reduced hormone production is just a consequence of a reduced metabolic request or instead represents a real protective condition against the increased catabolism seen in the aging process [ 38 ]. Numerous population-based studies have shown either a survival benefit, [ 1619838485 ] or no adverse impact of lower thyroid function.
