Hungry for A Cure: Prader Willi Syndrome

March 20, 2014

My 3-year-old daughter was born at 32 weeks. She was born with Prader-Willi Syndrome.

Prader-Willi syndrome (PWS) is the most common known genetic cause of life-threatening obesity in children. Although the cause is complex, it results from an abnormality on the 15th chromosome. It occurs in males and females equally and in all races. Prevalence estimates have ranged from one in 8,000 to one in 25,000 with the most likely figure being one in 15,000.

PWS typically causes low muscle tone, short stature if not treated with growth hormone, incomplete sexual development, and a chronic feeling of hunger that, coupled with a metabolism that utilizes drastically fewer calories than normal, can lead to excessive eating and life-threatening obesity. The food compulsion makes constant supervision necessary. Average IQ is 70, but even those with normal IQs, almost all have learning issues. Social and motor deficits also exist.

At birth, the infant typically has low birth weight for gestation, hypotonia (weak muscles), and difficulty sucking due to the hypotonia which can lead to a diagnosis of failure to thrive. The second stage (“thriving too well”), has a typical onset between the ages of two and five, but can be later. The hyperphagia (extreme unsatisfied drive to consume food) lasts throughout the lifetime. Children with PWS have sweet and loving personalities, but this phase is also characterized by increased appetite, weight control issues, and motor development delays along with some behavior problems and unique medical issues.

She also has Arnold Chiari Malformation of the brain. She has trach and is on the Vent and feeding tube…I just wish there was a cure. My baby is hungry 24/7 and it will never stop.
