Hyperthyroidism in the Elderly: A Case Report

Abstract

Background: Thyroid disorders in the elderly commonly occur as hypothyroidism but hyperthyroidism can also occur. Diagnosing thyroid disorders in the elderly can be difficult due to varying factors.  Among these is the age related decline of function of organ systems and the presence of morbid conditions in the elderly that often require medications some of which affect thyroid hormone metabolism. Subclinical hyperthyroidism is often the presentation rather than overt hyperthyroidism hence combining the physical presentation and thyroid investigations of an aged patient may be more useful in making effective clinical judgment. Aim: The aim of this case report is to show the variety of ways in which hyperthyroidism can present in the older adult. Methods:  Relevant clinical and biochemical data was retrieved from the case notes of 3 older adults who presented with clinical and biochemical evidence of hyperthyroidism to the University of Port Harcourt Teaching Hospital, Port Harcourt, Nigeria from 2015 to 2022. Conclusion: Hyperthyroidism in the elderly can present in variety of ways which may be different from the typical way in other age groups. The biochemical findings may not be clear cut in making diagnosis hence the need to acquire the clinical skill in combining the physical manifestations with the thyroid investigations.
