Prader-Willi syndrome is a rare disorder present at birth that results in a number of physical, mental and behavioral problems. A key feature of Prader-Willi (PRAH-dur VIL-ee) syndrome is a constant sense of hunger that usually begins after the first year of life.
People with Prader-Willi syndrome want to eat constantly and usually have trouble controlling their weight. Many complications of Prader-Willi syndrome are due to obesity.
If your child has Prader-Willi syndrome, a team of specialists can work with you to manage your child's symptoms and reduce the risk of developing complications.
