What is an Eating Disorder?
An eating disorder is a severe mental health condition characterised by unhealthy and often extreme behaviours, thoughts, and attitudes towards food, eating, and body weight or shape. These disorders can have significant physical, psychological, and social consequences, affecting individuals across various demographics, including age, gender, and cultural background.
Types of Eating Disorders
Anorexia Nervosa
Anorexia nervosa involves self-starvation and excessive weight loss. Individuals with anorexia have an intense fear of gaining weight and a distorted body image, often seeing themselves as overweight even when they are underweight. Symptoms include severe restriction of food intake, excessive exercise, and sometimes binge eating followed by purging behaviours like vomiting or misuse of laxatives.
Bulimia Nervosa
Bulimia nervosa is characterised by episodes of binge eating followed by compensatory behaviours such as self-induced vomiting, misuse of laxatives, fasting, or excessive exercise. Unlike anorexia, individuals with bulimia may maintain an average weight or be overweight. They often feel a lack of control during binge episodes and judge themselves harshly based on body shape and weight.
Binge Eating Disorder (BED)
BED involves recurrent episodes of eating large quantities of food, often quickly and to the point of discomfort. Unlike bulimia, binge eating episodes are not followed by purging behaviours. Individuals with BED may feel guilt, shame, or distress about their eating behaviours, which can lead to weight gain and obesity.
Avoidant/Restrictive Food Intake Disorder (ARFID)
ARFID is characterised by a persistent failure to meet appropriate nutritional and/or energy needs. This can be due to a lack of interest in eating, avoidance based on sensory characteristics of food, or concern about the aversive consequences of eating. ARFID can lead to significant weight loss, nutritional deficiency, and interference with psychosocial functioning.
Other Specified Feeding or Eating Disorder (OSFED)
OSFED includes eating disorders that do not meet the full criteria for the above disorders but still cause significant distress or impairment. Examples include atypical anorexia nervosa, bulimia nervosa of low frequency, and purging disorder.
Pica & Rumination Disorder
Pica involves eating non-food substances, while rumination disorder involves the repeated regurgitation of food. Both can lead to severe health complications and require medical attention.

Causes of Eating Disorders
Eating disorders are complex conditions with multiple contributing factors. The causes of eating disorders are not fully understood, but research suggests they arise from a combination of biological, psychological, and sociocultural factors. Here are some of the critical factors that may contribute to the development of an eating disorder:
Biological Factors
- Genetic predisposition: Eating disorders tend to run in families, suggesting a hereditary component.
- Brain chemistry: Imbalances in neurotransmitters and hormones may play a role.
- Body weight in childhood: Higher body weight in childhood may increase risk.
Psychological Factors
- Low self-esteem
- Perfectionism and striving to be perfect in one or more areas
- Poor body image
- Difficulty coping with stress
- History of trauma or abuse
- Neurodiversity
- Other mental health conditions like anxiety or depression
Sociocultural Factors
- Social pressure to be thin
- Media influences promoting unrealistic body ideals
- Bullying or teasing about weight
- Participation in activities that emphasise weight or body shape (e.g., modelling, gymnastics)
- Problems with friends or family relationships
- High academic expectations
Environmental Factors
- Stressful life events or significant changes (e.g., going to college, moving, new job)
- History of dieting, persistent dieting
- Exposure to weight stigma or body shaming
It’s important to note that eating disorders are not a choice or lifestyle decision. They are severe mental health conditions resulting from a complex interplay of these various factors. Each person’s experience with an eating disorder is unique, and the specific causes may differ from one individual to another. Early intervention and comprehensive treatment addressing these multiple factors are crucial for recovery.
Treatment of Eating Disorders
Eating disorders are typically treated using a multidisciplinary approach combining several interventions. The main treatment options include:
- Psychotherapy: This is a critical component of eating disorder treatment. Common approaches include:
- Cognitive Behavioral Therapy (CBT)
- Interpersonal Psychotherapy (IPT)
- Dialectical Behavior Therapy (DBT)
- Family-based treatment (FBT), especially for younger patients
- Nutritional counselling: A dietitian educates patients about healthy eating habits and helps them develop balanced meal plans.
- Medical care: This involves monitoring and treating physical health problems caused by the eating disorder.
- Medication: While there’s no specific medication for eating disorders, psychiatric medications may be prescribed to treat co-occurring conditions like depression or anxiety.
- Outpatient treatment: This is often the first line of treatment, where patients attend regular appointments with their treatment team.
- Higher levels of care: For more severe cases, options include:
- Day treatment programs
- Residential treatment
- Inpatient hospitalisation
- Family involvement: Especially important for younger patients, family members are often involved in treatment and may supervise meals.
- Support groups: These can provide additional emotional support and coping strategies.
The specific treatment plan is tailored to the individual’s needs, considering factors such as the type and severity of the eating disorder, any co-occurring conditions, and the person’s overall health status. Treatment aims to address both the physical and psychological aspects of the disorder, with the goals of normalising eating patterns, achieving a healthy weight, reducing eating disorder behaviours and thoughts, and treating any co-occurring conditions.
It’s important to note that recovery from an eating disorder can be a long-term process, and ongoing support and treatment may be necessary even after initial symptoms improve.
