According to the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) there are seven types of eating disorders: anorexia, bulimia, binge-eating, pica, avoidant/restrictive food intake disorder, rumination disorder and eating disorder not elsewhere classified.
Anorexia Nervosa (AN) – severe low body weight, intense fear of gaining weight, distorted body image and persistent behaviour that interferes with weight gain
Bulimia Nervosa (BN) – intake of large amounts of food followed by purging
Binge Eating Disorder (BED) – intake of very large amounts of food with no purging
Pica – craving and eating things not considered food e.g. dirt, ice, soap, hair
Avoidant/Restrictive Food Intake disorder (ARFID) – no interest in food, poor diet due to sensory issues or food refusal related to fear of choking, vomiting
Rumination Disorder (RD) – regurgitation of food that has been chewed and swallowed. Food is then rechewed and re-swallowed or spit out.
Eating Disorder Not Elsewhere Classified (EDNEC) – dysregulated eating that does not fit all diagnostic criteria of AN, BN, BED. For example, orthorexia, night eating syndrome, purging disorder
It is important to understand that eating disorders are not solely confined to food issues but are usually due to a range of psychological conditions that cause unhealthy eating habits to develop e.g. obsession with food, delusions, anxiety, fixation with body image, substance/alcohol use. Untreated eating disorders can lead to some very serious medical problems and research is finding that an eating disorder rarely exists in isolation but is usually accompanied with other mental disorders/illnesses e.g. depression, anxiety, substance abuse.
