Abstract
Diurnal variation in oral glucose tolerance was studied in 122 male volunteers aged 40 yearsand over who participated in a screening health examination. In those with screening blood sugar levels exceeding 110 mg./100 ml. the degree of diurnal variation was least in those with the highest morning glycaemia; the latter also tended to have lower afternoon fasting bloodsugar levels.
In a group of 40 control subjects, afternoon glucose tolerance tests yielded significantly higher post-glucose blood sugar levels. The degree of diurnal variation was significantly and inversely related to the degree of obesity.
