Building Your Child's Care Plan: Standard Treatments

Managing Prader-Willi Syndrome (PWS) requires a proactive, “whole-person” approach. Because PWS affects multiple systems—including growth, metabolism, and behavior—the gold standard of care is a multidisciplinary team ^[1]. This team typically includes an endocrinologist, a specialized nutritionist, a sleep specialist or pulmonologist, a behavioral therapist, and various physical therapists ^[2].

Growth Hormone (GH) Therapy

Growth Hormone therapy is a cornerstone of modern PWS management. Administered via a daily subcutaneous injection (a small shot under the skin), it is not just about height; it fundamentally changes how the body is built ^[3].

Benefits of GH Therapy

• Body Composition: GH significantly improves muscle mass (lean body mass) and helps reduce body fat ^[4].
• Growth and Stature: It helps children reach a height more in line with their peers ^[3].
• Bone Health: GH therapy has a positive effect on bone mineral density, making bones stronger as children grow ^[5].

Risks and Safety Monitoring

While GH is widely used and highly effective, it requires careful medical oversight:

• Sleep-Disordered Breathing: In some children, GH can worsen obstructive sleep apnea (where breathing stops and starts during sleep) ^[3]. Doctors recommend a polysomnography (sleep study) before starting treatment and regular follow-ups ^[6].
• Respiratory Infections (Critical Warning): Pediatric patients with PWS on GH therapy have an increased risk of sudden death associated with severe obesity or acute respiratory infections ^[3]. Parents must be extremely vigilant and promptly report any severe colds, chest congestion, or respiratory infections to their doctor.
• Scoliosis Monitoring: Children with PWS have a higher risk of developing scoliosis (curvature of the spine). While GH does not seem to cause scoliosis, your child will need regular spine checks while on the medication ^[7].

Managing Hyperphagia

Hyperphagia—the insatiable drive to eat—is a physiological symptom of PWS that cannot be “cured” with willpower or traditional dieting. Instead, it is managed through environmental control and structure ^[8].

• Food Security: Creating a “food-secure” environment is essential. This often involves locking cabinets or pantries and providing a highly predictable meal schedule to reduce the child’s anxiety around food ^[9].
• Caloric Management: Because individuals with PWS have a lower metabolism and less muscle mass, they require fewer calories than their peers to maintain a healthy weight ^[10]. A nutritionist will help create a specialized, nutrient-dense plan.

Early and Ongoing Therapy

From infancy, Physical Therapy (PT) and Occupational Therapy (OT) are critical to address neonatal hypotonia (low muscle tone), promoting the strength needed to reach milestones like crawling and walking ^[11]. Furthermore, early Behavioral Therapy is crucial to help parents establish rigid routines and prepare strategies to manage the unique behavioral challenges (temper tantrums, stubbornness, skin-picking) that will emerge as the child grows ^[12].
