Key features of obsessive weight losing disorders
Obsessive fear of fatness with avoidance of food and other sources of calories
A range of compulsive compensatory behaviours when food cannot be avoided
In time these behaviours are the only way to avoid the experience of anxiety AND there are secondary physical and psychological consequences of starvation
ICD-10 classification for anorexia nervosa

Examples of compensatory behaviours
Self induced vomiting/purging excessive exercise abuse of appetite suppressants / diuretics / laxatives strict diet fasting
How can constipation of anorexia nervosa relate to the psychological aspect of it?
Gut slows down - reduced peristalsis and so this can lead to e.g. a tight tummy which can contribute to the psychological aspect
What is bulimia nervosa?
Binges and the resulting compensatory behaviour - which must occur a minimum or two times per week for 3 months
