MEDICAL CONDITIONS WHICH MAY AFFECT PEOPLE WITH PRADER-WILLI SYNDROME


In addition to the most common characteristics of PWS, there are some other medical problems which may affect people with PWS, or conditions which may cause complications in medical treatment. Not everyone with PW S will have all of the problems listed below, but it is likely that most people will have some of the problems. However, generally speaking, people with PWS are often very healthy.

Adverse reaction to drugs and anaesthetics

  • prolonged drowsiness after routine anaesthesia.
  • abnormal response to some tranquillising drugs.
  • abnormal response to slimming pills and appetite suppressants.

Poor control of body temperature

  • erratic behaviour and/or lethargy may occur in very cold or very hot weather.
  • risk of hypothermia in very cold weather.
  • infections occasionally do not cause the usual rise in body temperature, or can cause an unusually high temperature.
  • poor circulation.

High pain threshold - insensitivity to pain

  • may mask severity of injuries or disease.
  • the person may be unaware of relatively severe internal disorders.

Skin problems

  • picking at the skin, finger and toe nails, or at insect bites may result in infections.
  • rectal picking may occur and should he considered first in any conditions relating to the rectum.
  • cellulitis may occur, especially in overweight adults. Oedema may result in lymphatic obstruction, which places people at risk of recurrent cellulitis.
  • intertrigo (superficial inflammation occurring in moist skin folds).

Easy bruising

  • fairly slight injuries may result in large bruises. The person with PWS may not be able to say how the bruises occurred (due to high pain threshold).

Lack of vomiting

  • due to poor muscle tone, people with PWS are often unable to vomit.
  • seek medical assistance immediately if the person has eaten or drunk poisonous substances.

Diabetes

  • diabetes mellitus may develop in overweight teenagers and adults.

Sleep apnoea (cessation of breathing for short periods whilst asleep)

  • relatively common in PWS, often, but not always, in those who are significantly over weight.
  • can occur in children with PWS.

Scoliosis and other forms of curvature of the spine

  • regular checks should be made on the spine to ensure there is no onset of scoliosis, which may occur at any age.
  • The above are not exhaustive characteristics or reactions, and more specific information on PWS can be obtained from the PWSA (UK) or its medical advisors.
