Observations in Hyperthyroidism of Abnormal Glucose Tolerance and Other Traits Related to Diabetes Mellitus

Studies were made of glucose tolerance and other characteristics related to diabetes in fifty-one patients with hyperthyroidism. Glucose tolerance compatible with diabetes was present in 57 per cent of patients when toxic and 30 per cent on return to euthyroidism. Histories of family diabetes in both sexes and of heavy babies delivered by the women were obtained more frequently than expected in the general population. Reasons are given to suggest a genetic relation between hyperthyroidism and diabetes.
