BURDEN ON CAREGIVERS AND FAMILIES
The 24/7 dedication to loved ones with hyperphagia in PWS means caregivers experience burdens
of their own. Accommodating for a loved one living with PWS may also come at the expense of family dynamics.11,12
Caregivers
- Employment challenges11
- Risk of physical harm13,14
- Significant mental load14
- Minimal flexibility with routines1,3
- Required to fulfill a multitude of roles11,13-15
Families
- Siblings experience PTSD12
- Negative impact on marriage and relationships11
- Greater annual medical costs16
- Increased complexity around planning family and social gatherings3
Every aspect of life is impacted by the burden of PWS.3
