Summary The results are presented of glucose tolerance tests on 85 apparently non‐diabetic male subjects, 58 of them aged over 54 years. The results were as follows : 47 “normal” ; 11 “glucose tolerance test diabetics” ; 15 “lag‐storage”; 9 “group C” ; and 3 “unclassifiable”. In the older groups of the subjects studied, there was a tendency for the peak of the curve to be displaced to the right, and it is therefore suggested that the test period for the G.T.T. should be increased to three hours for subjects aged over 54 years, and that diagnostic post‐prandial blood sugar levels should be estimated at this time. The association of abnormal glucose tolerance and the clinical manifestations of vascular disease is discussed, as well as the possible effect of medication being taken by the patients. It is concluded that, although there is a decline in glucose tolerance as age advances, it is likely to be overemphasized if a two‐hour test is used, and inadequate notice taken of current medication.
