What is Prader-Willi Syndrome?

Prader-Willi syndrome (PWS) is a rare, complex genetic disorder that affects both males and females from birth and throughout their lives. It causes low muscle tone with consequent motor developmental delays, a mild to moderate learning difficulty, and emotional and social immaturity, which can lead to challenging behaviours.

During childhood, an overwhelming and insatiable chronic appetite usually develops which, without rigorous food management and exercise regimes, leads to food seeking and life threatening obesity.

PWS occurs randomly in about 1:15,000 births.
