Eating & Feeding Disorders are a cluster of disorders involving abnormal
eating behaviours or a disturbed connection with food or with body
weight. These problems may involve eating too much or too little, avoiding
certain meals, or having difficulty getting enough nutrition. They can
occur in children, adolescents, or adults and often affect physical health,
mental health, and daily functioning.
The most common eating & feeding disorders are anorexia nervosa, bulimia
nervosa, binge-eating disorder, avoidant/restrictive food intake disorder
(ARFID), pica, and rumination disorder. Symptoms can include drastic
weight swings, nutritional inadequacies, fear of gaining weight, decreased
appetite, binge eating episodes, food avoidance, or strange eating
patterns. Feeding issues in children can cause poor growth, developmental
delay, or inadequate intake of nutrients.
The aetiology of these illnesses is complicated, involving genetic, psychological, environmental, social, and biological variables. Stress, anxiety, sadness, trauma, body image problems, and family pressures may play a role in their development.
