Prader-Willi syndrome (PWS) is a complex genetic disorder localized to chromosome 15 and is considered the most common genetic cause of the development of life-threatening obesity. Although some morbidities associated with PWS, including respiratory disturbance/hypoventilation, diabetes, and stroke, are commonly seen in obesity, others such as osteoporosis, growth hormone deficiency, and hypogonadism, and also altered pain threshold and inability to vomit, pose unique issues. Various bariatric procedures have been used to cause gastric stasis, decrease gastric volume, and induce malabsorption, with poor results in PWS patients in comparison with normal obese individuals.
