The aim of this study is to evaluate the frequency and relative import
ance of different aspects of health related quality of life (HRQOL) im
pairment in patients with hypothyroidism. A survey of 200 patients wit
h treated hypothyroidism was undertaken. Patients were identified and
questionnaires distributed through family physicians, endocrinologists
, and regional branches of the Thyroid Foundation of Canada. Frequency
of importance of patients' symptoms attributed to hypothyroidism and
resolved or improved with treatment were measured. Establishing the wi
de variety of patient-specific complaints associated with hypothyroidi
sm provides guidance for clinicians dealing with hypothyroid patients,
and investigators interested in HRQOL impairment in these patients.
