ABSTRACT
This chapter presents a case of a 17-year-old girl who is admitted to casualty having fainted during a games lesson at school. She is embarrassed by the fuss she has caused and insists she is okay. Vomiting may lead to hypokalaemia which can be dangerous particularly if it changes rapidly. Amenorrhoea may be present in those who have started their periods, as the body seeks to conserve resources. It is tending to occur in younger and younger children. The aetiology is multi-factorial and it is thought that media representations of women play a major role in the disorder. It is important to undertake a thorough assessment and a corroborative history. Acute management needs to make sure she is medically safe, so rehydration would be the first step as she is dehydrated. The priority will be to work towards gradual and sustained weight gain and cognitive behaviour therapy (CBT).
