Three @entity1 , aged 16, 70 and 72 years, were seen in our outpatients' clinics with a decreased TSH value. In two of them, @entity1374 was not the cause of the low TSH activity. In @entity1 A, the cause was diminished food intake and in @entity1 B, who was also known with nodular @entity1374 , the cause was the use of glucocorticoids. Only @entity1 C had @entity1378 due to goitre with concomitant @entity955 . She was recommended for treatment with 131I. @entity1 A and B recovered spontaneously. @entity1378 is being increasingly encountered due to the availability of sensitive assays for measuring TSH activity and the increased frequency with which general practitioners test thyroid function. However, in about 55% of cases suppressed TSH values normalise spontaneously. This means that it is important to establish if @entity1374 is truly present. The treatment of @entity1378 should be initiated on the basis of individual data.
