Ghrelin in Health and Disease

Ghrelin, the endogenous ligand for the growth hormone secretagogue (GHS) receptor, is critical in the control of food intake and energy balance. The ghrelin receptors are now known to have important physiological properties as modulators of growth hormone

Preface

The past 5–10 years has seen an explosion of publications on the pharmacological properties of ghrelin and the implications of how this information might extrapolate to understanding ghrelin’s role in normal physiology. The pharmacological studies prompted evaluation of the potential benefits of ghrelin as a therapeutic agent in a plethora of disease states. Ghrelin treatment appears to be very well tolerated and the results are encouraging. For chronic use the short half-life and poor oral bioavailability of ghrelin will contin
