Prader-Willi syndrome (PWS) is a neurodevelopmental genetic disorder. The main features include infantile hypotonia, a poor suck, failure to thrive and hypogonadism/hypogenitalism. Short stature and small hands/feet due to growth and other hormone deficiencies, hyperphagia and marked obesity occur in early childhood. Cognitive and behavioural problems (tantrums, compulsions, compulsive skin picking) are common1 .
