Quality of life is reduced in patients with thyroid dysfunction
and goiter
(July 2004)
The background of the study. Thyroid disorders
are common, but many patients have few symptoms, and the effect
on their quality of life is uncertain. This study assessed the quality
of life in patients with thyroid disorders.
How the study was done. The study subjects were
275 women and 42 men, aged 18 to 85 years, who were evaluated for
symptoms or because of abnormal test results suggesting the presence
of a thyroid disorder. Thirty-six patients had overt hypothyroidism,
45 subclinical hypothyroidism, 27 overt hyperthyroidism, 18 subclinical
hyperthyroidism, and 191 goiter. The patients were asked about mood,
behavioral, and sleep problems and their opinion of their health;
they completed two standardized questionnaires about physical and
mental health. The results were compared with those obtained in
two large population studies.
The results of the study. A substantial proportion
of the patients in all groups reported mood and behavioral problems,
sleep problems, and changes in perceived health during the previous
year. The scores on the questionnaires were slightly lower than
those in the normal subjects, and they were more abnormal in the
patients with overt thyroid dysfunction than in those with subclinical
thyroid dysfunction.
The conclusions of the study. Patients with thyroid
dysfunction or goiter have decreased quality of life.
