    Prader-Willi Syndrome Treatments and Managment

    Explore treatments and therapies for managing the symptoms of PWS.

    Although there is currently no cure for Prader-Willi syndrome (PWS), early diagnosis and comprehensive medical care can significantly improve health, development, and quality of life.

    Today’s treatments focus on managing symptoms, improving health, and helping people with PWS live fuller, healthier lives, and research is creating new reasons for hope. 

    Treatment options for PWS continue to expand. Recent advances include the first FDA-approved treatment for hyperphagia, while genetic therapy research is working toward treatments that may one day address PWS at its source.

    Growth Hormone

    Growth hormone therapy is a standard treatment for children with PWS and can also benefit adults. Beyond increasing height, it can improve body composition, muscle mass, bone health, stamina, and motor development. Research also suggests possible benefits for cognition and behavior.

    Because many benefits are greater when treatment begins early, babies and children with PWS should be evaluated for growth hormone therapy soon after diagnosis. Treatment should be prescribed and monitored by an endocrinologist familiar with PWS.

    Developmental Therapies

     

    PWS can affect muscle tone, motor skills, communication, learning, and social development. Early intervention often begins in infancy, with support changing as a child grows.

    Depending on individual needs, support may include physical therapy, occupational therapy, speech-language therapy, early intervention services, and educational accommodations.

    Vykat for Hyperphagia

    One of the defining features of Prader-Willi syndrome is hyperphagia—a persistent, biological drive to eat caused by changes in the brain's regulation of hunger and satiety.

    Treatment options are expanding. VYKAT™ XR (diazoxide choline) is the first FDA-approved medication for hyperphagia. While medication represents an important advance, it is intended to complement—not replace—nutrition, food security, physical activity, and other aspects of comprehensive care.

    Nutrition and Weight Management

    Hyperphagia is much more than an increased appetite—it is a chronic medical symptom that requires lifelong management.


    People with PWS may also need fewer calories because of reduced muscle mass and lower energy expenditure, making lifelong nutrition and weight management an essential part of caring for the person with PWS.

    Care often includes:

    • A nutritionally balanced, reduced-calorie diet
    • Structured meals and snack times
    • Food security strategies that limit unsupervised access to food
    • Regular physical activity
    • Ongoing monitoring of growth, weight, and body composition
    • Support from healthcare providers

     

    Endocrine and Hormone Care

     

    Hormone-related conditions are common in PWS and need monitoring throughout life. These can include low thyroid hormone and low levels of sex hormones, which can affect puberty, bone health, muscle development, energy, and other aspects of health.

    Hypogonadism, or low production of sex hormones, is especially common in PWS. An endocrinologist familiar with PWS can monitor hormone levels and development and recommend hormone replacement when appropriate.

    Behavioral and Mental Health Support

    Behavioral and emotional challenges are common in PWS and can change throughout life. Children and adults may experience anxiety, rigidity, emotional outbursts, repetitive or obsessive behaviors, difficulty with transitions, and challenges with social interactions. Some people with PWS may also develop mental health conditions that require specialized care.


    Many of these challenges are shaped by the biology of PWS. Consistent routines, predictable environments, behavioral support, and, when appropriate, medication can help reduce distress and support individuals and families.

    Sleep Disorders and Excessive Daytime Sleepiness

    Sleep problems are common in PWS and can affect health, learning, behavior, and quality of life. These may include sleep apnea and other breathing disorders, disrupted nighttime sleep, and excessive daytime sleepiness. Daytime sleepiness can persist even when nighttime sleep and sleep apnea are appropriately treated.

    Evaluation by a sleep specialist can help identify the cause and guide treatment. Depending on the individual, treatment may include support for sleep-disordered breathing, such as CPAP or BiPAP, or medication to improve daytime alertness.

    Scoliosis and Orthopedic Care

    Scoliosis is common in Prader-Willi syndrome and may affect up to 70% of people with PWS by skeletal maturity. Curvature of the spine can develop in infancy, childhood, or adolescence, so regular screening is an important part of routine care.

    When scoliosis is present, treatment depends on the severity and progression of the curve and may include monitoring, bracing, physical therapy, or surgery. Growth hormone has not been shown to increase the risk or progression of scoliosis, but the spine should continue to be monitored during treatment.

     

    Additional Health Considerations

    In addition to the core features of Prader-Willi syndrome, individuals with PWS often experience many other medical conditions that require ongoing monitoring and treatment. Although these concerns vary from person to person, recognizing them early can help prevent complications and improve quality of life.

     

    Constipation
     

    Constipation is common in people with PWS and can easily go unrecognized. Low muscle tone, slower movement through the digestive tract, and limited fluid intake can all contribute.

    Treatment focuses on keeping bowel movements soft and regular. Some PWS specialists describe constipation medications as “mushers and pushers”: osmotic laxatives help soften stool by drawing in fluid, while stimulant laxatives help move stool through the intestines. A healthcare provider can recommend the right approach based on individual needs.

    Persistent constipation, abdominal pain or swelling, vomiting, or a significant change in bowel habits should be discussed with a healthcare provider.

    Skin Picking

    Skin picking is a common behavior in people with PWS and can range from mild to severe. Repeated picking may lead to open wounds, infection, and scarring. Treatment typically includes behavioral strategies, protecting the skin, treating underlying wounds, and, in some individuals, medication. Research has also explored the use of N-acetylcysteine (NAC) as a potential treatment for reducing skin-picking behaviors in some individuals with PWS.

     

    Oral Health

    Individuals with PWS face many of the same common dental issues as the general population. However, low saliva production and high rates of teeth grinding in PWS create additional stressors that can make it more difficult to maintain healthy teeth and gums. A strong oral hygiene routine and regular dental visits can help prevent some of these dental problems, and early treatment can help keep them from worsening.

    Frequently Asked Questions

    Is there a cure for Prader-Willi syndrome?

    Not yet. There is currently no cure for Prader-Willi syndrome. Current treatments focus on managing symptoms and improving health while researchers develop disease-modifying therapies, including genetic therapies that aim to address the underlying cause of the disorder.

    Can hyperphagia be treated?

    Hyperphagia is a lifelong medical condition that is best managed through a combination of food security, structured routines, nutritional management, regular physical activity, behavioral strategies, and medication when appropriate.

    VYKAT™ XR (diazoxide choline) is currently the only FDA-approved treatment for hyperphagia in people with PWS. Medication is intended to complement these environmental and behavioral strategies for managing hyperphagia—not replace them. 

    Is growth hormone therapy recommended for children with PWS?

    Yes. Growth hormone therapy is a standard treatment for most children with Prader-Willi syndrome and is often started in infancy. Benefits extend beyond height and can include improved muscle mass, body composition, bone health, physical function, and motor development. Children should be evaluated by an endocrinologist familiar with PWS before treatment begins and monitored regularly during therapy.



    Is growth hormone therapy recommended for adults with PWS?

    Yes. Growth hormone therapy can also benefit adults with Prader-Willi syndrome. Research has shown improvements in body composition, including increased lean body mass and reduced body fat, as well as benefits for muscle strength and exercise capacity. Treatment should be individualized and monitored by an endocrinologist familiar with PWS. 

    What are the symptoms of Prader-Willi syndrome?

    Symptoms of Prader-Willi syndrome vary by age. Infants commonly have low muscle tone (hypotonia), feeding difficulties, poor growth, and developmental delays. During early childhood, excessive hunger (hyperphagia), rapid weight gain, short stature, hormone deficiencies, learning differences, and behavioral challenges often become more apparent.

    What treatments are available for Prader-Willi syndrome?

    Treatment for Prader-Willi syndrome typically includes growth hormone therapy, nutrition and weight management, food security strategies, physical activity, developmental therapies, hormone replacement when needed, behavioral support, and regular medical care. Some individuals may also benefit from medications such as VYKAT™ XR, the only FDA-approved treatment currently indicated for hyperphagia in people with PWS.

    Are new treatments for Prader-Willi syndrome being developed?

    Yes. Researchers are developing new treatments for several aspects of PWS, including hyperphagia, excessive daytime sleepiness, behavior, and other symptoms. Genetic therapies are also being studied with the goal of addressing PWS at its underlying genetic source.

    FPWR helps advance this work by funding research and supporting the path from discovery to clinical trials.



    What is the life expectancy of someone with PWS?

    Individuals with PWS have a higher mortality rate than typical individuals across the lifespan, but life expectancy in the PWS population has improved significantly because of earlier diagnosis, better nutrition, growth hormone therapy, and improved medical care. Maintaining a healthy weight and managing obesity-related complications are key factors in improving long-term health. Today, many people with Prader-Willi syndrome are living healthier and longer lives than ever before, with many individuals living into their 50s, 60s, and beyond.

     

    Research is changing the future of PWS

     

    The outlook for people with Prader-Willi syndrome has changed dramatically over the past decade. For years, treatment focused primarily on managing symptoms through nutrition, hormone therapy, developmental supports, and specialized medical care. Today, a growing pipeline of new therapies is expanding treatment options while researchers pursue approaches that may one day address the underlying genetic cause of PWS.

    This progress is creating more treatment options and new possibilities for people with PWS to live healthy, fulfilling lives.

    FPWR is helping drive this progress by funding innovative research, supporting clinical trials, developing tools such as the Global PWS Registry, and bringing together scientists, clinicians, industry partners, and families to accelerate better treatments and, ultimately, a cure.
