The clinical presentations of thyroid disorders are often subtle in ol
der adults and may be confused with ''normal'' aging. To avoid delay i
n diagnosis, we recommend, routine TSH screening of all patients age 6
0 and older in the primary care practice. With hypothyroidism, pursue
treatment cautiously; start with small doses of levothyroxine and clos
ely monitor serum TSH values. When hyperthyroidism is caused by Graves
' disease, begin symptomatic therapy with a beta blocker or antithyroi
d drugs, followed by definitive thyroid ablation with radioiodine. Sur
gical treatment may be indicated if a goiter causes compressive sympto
ms.
