Insulin secretion and insulin sensitivity were measured in hypertriglyceridemic patients using the frequently sampled intravenous glucose tolerance test. Three groups of men who were matched for age and body mass index were studied: eight healthy control subjects (C), seven patients with mild hypertriglyceridemia and normal glucose tolerance (TG), and seven with well-controlled type 2 diabetes with hypertriglyceridemia (TG-DM). The first-phase insulin response was increased by 116% in the TG group and decreased by 59% in the TG-DM group. The second phase of insulin secretion was increased in both TG groups (TG by 310% and TG-DM by 250%). The mean insulin sensitivity index (SI) was reduced by 50% in the TG group and by 60% in the TG-DM group. Glucose effectiveness (SG) was reduced by 30% in the TG-DM group compared with the control subjects.
