*** ABOUT PWS ***
Prader-Willi syndrome (PWS) is the most common known genetic cause of life-threatening obesity. With early diagnosis and proper management, the health and quality of life of the child with the syndrome can be significantly more positive than in past generations.
PWS is a multiple-system genetically determined variable disorder among whose most prominent characteristics are developmental delay/mild intellectual disability, childhood-onset excessive eating leading to severe obesity if uncontrolled, and behavioral difficulties. In infancy, its most striking finding is severely diminished muscle tone leading to poor sucking and often failure to gain weight and grow properly. The major and minor findings that characterize PWS are detailed below. Several of them are related to alterations in normal brain clues (such as feeling full after eating) or hormone production (such as insufficiency of growth hormone).
The characteristic difficulties seen in people with PWS can be treated, although currently PWS cannot be cured. One of the most important aspects of managing PWS is for parents and caregivers to implement rules and structure for the day for the person with PWS and set consistent limits. Treatment with growth hormone replacement has been shown to help with many aspects of the disorder including improving growth, muscle development, the proportion of fat, weight control, and activity level, and recent evidence suggests it may also improve cognitive ability.
PWS affects males and females of all ethnicities equally in all parts of the world. It occurs in approximately 1 in 10,000 to 30,000 people.

IPWSO is the international non-profit support group for all countries where there is even just one person with PWS! Our international umbrella supports all country PW Associations, and for all countries where there are no formal PW Associations, we support medical and parent delegates as part of our huge community. IPWSO has 102 country members, and is a world-wide parent-led support organisation.
