Does any of this apply?
Book an appointment
Arrange routine medical follow-up for growth, weight, nutrition, development, hormone function, sleep, behaviour, bone health, and scoliosis.
Seek a timely appointment if there is new snoring, daytime sleepiness, rapid weight change, reduced mobility, worsening skin wounds, or a lasting change in mood or behaviour.
The article also says
People with PWS may not show pain, fever, or vomiting in the usual way.
A clear change from their normal behaviour or energy level can therefore be medically important.
Every sign above is quoted from the sofidex article on Prader-willi syndrome. If you are not sure, err upward — it is always reasonable to be checked.
