KOHLENHYDRATSTOFFWECHSEL BEI HYPERTHYREOSE: EINFLUSS EINER THYREOSTATISCHEN THERAPIE AUF ORALE UND INTRAVENÖSE GLUCOSETOLERANZ UND INSULINAKTIVITÄT

Abstract
The influence of antithyroid therapy on the abnormalities of carbohydrate metabolism observed in hyperthyroidism was investigated in 10 patients. No history of diabetes mellitus was known in the patients or their families. 9 normal persons were taken as a control group. An oral and an intravenous glucose tolerance test were administered prior to and at intervals of 2 and 4 weeks after initiation of therapy. Prior to treatment an inpairment of oral glucose tolerance was observed, whereas the glucose assimilation coefficient in the intravenous glucose tolerance test was normal. Both tests however, revealed a significant rise in insulin values above normal. 2 weeks after initiation of therapy insulin values returned to normal during the intravenous glucose tolerance test. During the oral glucose tolerance test glucose and insulin concentration achieved normal levels only after 4 weeks of treatment. In all patients the abnormalities of carbohydrate metabolism observed were reversible.
