Objectives: Insulin resistance (IR) and obesity are very common metabolic abnormalities, which are often associated with reduced GH secretion. GH reduces intraabdominal fat and its deficiency may contribute to the metabolic syndrome. IGF-1 improves IR but IGFBPs have a potential role in regulating its bioactivity although only little information exists. We postulate that the elevated insulin levels in IR may persistently suppress GH provided its regulation remains insulin sens...

Glucagon-induced suppression of ghrelin secretion is exerted at hypothalamus-pituitary level and is not mediated by an increase in catecholamine secretion

Objective: The mechanisms underlying the well known glucagon-induced satiety effect are unclear. We showed earlier that glucagon induces a remarkable decrease in the orexigenic hormone: ghrelin. It was the aim of the present study to further evaluate the effect of glucagon on ghrelin secretion and the possible site of origin of this effect.Methods: We studied the endocrine and metabolic responses to intramuscular glucagon administration in 23 subjects (1...
