Hyperghrelinemia does not accelerate gastric emptying in Prader-Willi syndrome patients.
Prader-Willi syndrome (PWS) is the most common form of syndromic obesity associated with hyperphagia. Because ghrelin stimulates gastric motility in rodents, and PWS patients have 3- to 4-fold higher fasting plasma ghrelin concentrations than normal subjects, we hypothesized that hyperphagia associated with PWS may be partly explained by rapid gastric emptying due to the increased gastric motil...

متن کاملMorbid obesity in an adolescent with Prader-Willi syndrome.
Prader-Willi syndrome is an uncommon multisystem genetic disorder caused by defects of chromosome 15 (15qll-ql3), often due to deletions or uniparental disomy The syndrome is characterized by neonatal hypotonia, dysmorphic facial features, short stature, motor and mental disabilities, behavioral changes, hyperphagia, precocious obesity and hypogonadotropic hypogonadism. We present a 17 year-old...
متن کاملPrader-Willi syndrome.
Prader-Willi syndrome is a multi system disorder characterized by neonatal hypotonia, later obesity, hyperphagia and mental retardation. It occurs sporadically, either as a result of microdeletion of chromosome 15p (70%) or as a result of maternal disomy of chromosome 15 (30%). The major problems encountered by parents are those of hyperphagia, food-seeking and obesity, and conduct disorder, pa...
