Abstract
As people age, significant functional changes occur in the endocrine system and specific endocrine organs, such as the thyroid. Thyroid diseases are more common as people age, and it is well known that the thyroid gland undergoes a number of morphological and physiological changes as people age. It should be emphasized that the clinical course of thyroid problems in the elderly is fundamentally different from that seen in younger people since the symptoms are more subdued and frequently mistaken for the signs of aging. In older people, additional care is needed for thyroid neoplasms and subclinical hypo- and hyperthyroidism. Interestingly, a longer lifespan may be attributed to both diminished thyroid function and thyrotropin (TSH) levels, which gradually increase with age. Recent research on the changes in thyroid function with age, including those that might result in longer lifespans in both people and animals, is the main topic of this brief overview.
