What Is Prader-Willi Syndrome? A Guide for Caregivers

Jun 26

Prader-Willi Syndrome (PWS) is a rare and complex genetic disorder that affects approximately 1 in 15,000 to 1 in 30,000 people worldwide. Often diagnosed in infancy, PWS requires lifelong care, support, and specialized resources for both the child and their family. At Raregivers, we recognize the challenges of caregiving for a child with a rare disease like PWS and are here to support you every step of the way.

What Causes Prader-Willi Syndrome?

PWS is caused by the loss of function of specific genes on chromosome 15. This genetic anomaly can occur due to a deletion, uniparental disomy, or an imprinting defect. The condition is not inherited in most cases and usually occurs as a random genetic event.

Symptoms and Challenges of Prader-Willi Syndrome

The hallmark features of PWS change over time. In infancy, symptoms include:

Severe hypotonia (low muscle tone)
Poor feeding and weak sucking reflex
Delayed motor development

As children grow, they may develop:

Hyperphagia (insatiable appetite), which can lead to obesity without strict food supervision
Intellectual and developmental delays
Behavioral issues, including compulsive behaviors and temper outbursts
Hormonal imbalances and delayed puberty

What Caregivers Should Know

Caring for a child with Prader-Willi Syndrome demands an incredible amount of emotional, physical, and financial resilience. Rare disease caregivers often face burnout, isolation, and emotional distress. Key tips for caregivers include:

Establish a strict food environment to manage hyperphagia
Work with a team of specialists, including endocrinologists, dietitians, and behavioral therapists
Create a structured, low-stress home environment

Prioritize your own mental health—caregiver burnout is real and serious
