anomaly in the production and/or regulated release from pancreatic epsilon cells of a 28-amino acid, acylated, orexigenic peptide that acts centrally to stimulate growth hormone secretion and food intake, and peripherally to regulate energy homeostasis; it is cleaved from a large precursor protein, known as appetite-regulating hormone or motilin-related peptide, which contains both ghrelin and obestatin
