Common features of Eating 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.
Anorexia Nervosa

Considered anorexic if they are 15% below ideal body weight
Fear of weight gain
Bulimia Nervosa
Episodes of binge eating with a sense of loss of control. Bing eating is followed by compensatory behaviour of the purging type. Binges and the resulting compensatory behaviours must occur a minimum of two times per week for three months. There is a dissatisfaction with body shape and weight.
Avoidance of Calorie Intake
Diets - becoming vegetarian, vegan etc. Interpreting all symptoms as allergy. Eating very slowly, only eating at certain times. Avoiding parties and social occasions. Medication abuse.
Getting Rid of Calories
Self-induced vomiting, chewing and spitting out, overexercising, overactivity, cooling, blood letting, medication abuse (omitting insulin)
“Anorexic Police Force”
Body-checking, displaying emaciation to elicit reassuringly shocked attention, cruising “por-ana” websites, competing with self and others to attain lower and lower targets, deliberate self harm if rules are broken
Psychological consequences of eating disorders
Cognitively impaired, reduced attention span, difficulty interpreting emotion (this is usually better with nutrition). Malnourished brains experience depression, anxiety, obsessionality and loss of concentration. This rarely responds to medication due to the low weight.
Social consequences of eating disorders
Withdrawal from friendships and sexual relationships
Physical consequences of eating disorders
Starvation causes physical damage, poor repair and resistance, heart damage, reduced immunity to infections, anaemia, bone loss, fertility problems. Purging behaviours cause neuro-chemical disruption with special damage to the brain and the heart.
