Hyperinsulinaemia in non-obese subjects with hypertriglyceridaemia: a preliminary report.

: It has been known for some time that hyperinsulinaemia is associated with hypertriglyceridaemia. However, previous studies looking at the relationship between hyperinsulinaemia and hypertriglyceridaemia have included overweight subjects. The effect of obesity on the insulin status of hypertriglyceridaemic patients is uncertain. We investigated the insulin status of hypertriglyceridaemic subjects in the absence of confounding factors such as obesity, hypertension and diabetes mellitus. Our results demonstrate that basal insulin levels as well as the insulin response after an intravenous glucose challenge are higher in moderately hypertriglyceridaemic patients when compared to age and body mass index matched controls. Hyperinsulinaemia may have pathogenetic significance for hypertriglyceridaemia as well as other features of a constellation of metabolic derangements such as obesity, hypertension and glucose intolerance.
