Mental development is slow and the IQ seldom exceeds 80. Children with Prader-Willi generally are very happy, smiling, and pleasant to be around. Affected children have an intense craving for food and will do almost anything to get it. This results in uncontrollable weight gain. There is no known prevention.
Obesity represents the greatest problem to health.
Limiting caloric intake will control the obesity but the family, neighbors, school and other institutions must cooperate as the child will attempt to obtain food wherever possible. Hypogonadism may be corrected at puberty with hormone replacement. Appropriate education will be needed for the affected person's IQ level. Weight control will allow for a much more comfortable and healthful life. Call for an appointment with your health care provider if your child has symptoms of this condition.
