What are eating disorders?

Eating disorders are complex and multifactorial conditions that result from a combination of biological, psychological, and environmental factors. Some of the possible causes or risk factors are:

• Genetics: Some people may inherit genes that make them more vulnerable to developing eating disorders. For example, a recent study found a new genetic link between anorexia nervosa and being an early riser.
• Personality: Some personality traits, such as perfectionism, low self-esteem, impulsivity, or obsessive-compulsiveness, may be associated with eating disorders. People with eating disorders may also have difficulties coping with emotions, stress, or trauma.
• Sociocultural: The social and cultural norms and expectations around food, weight, and appearance may influence eating disorders. For example, people may face pressure to conform to unrealistic or unhealthy beauty standards or experience discrimination or bullying based on their body shape or size.
• Other factors: Medical conditions, medications, life transitions, or stressful events may also trigger or worsen eating disorders. For example, some people may develop eating disorders after experiencing illness, injury, pregnancy, or menopause.

Eating disorders can manifest in different types and forms, each with its characteristics and challenges. Some of the most common ones are:

• Anorexia nervosa: A condition characterized by weight loss and a distorted body image, in which the person has a fear of gaining weight. People with anorexia dramatically restrict the calories and types of foods they consume, may exercise compulsively, and, in some cases, purge by vomiting or using laxatives.
• Bulimia nervosa: A condition characterized by episodes of bingeing and purging. Bingeing involves eating food — sometimes an extremely large amount — in a short period. During bingeing, people feel like they have no control over their eating and that they can’t stop. After eating, due to guilt, shame, or an intense fear of weight gain, purging is done to get rid of calories. Purging can include vomiting, exercising too much, not eating for some time, or using other methods, such as taking laxatives.
• Binge eating disorder: A condition characterized by excessive eating without purging. People with binge eating disorder eat large amounts of food in a short time, often when they are not hungry or after they are full. They feel a loss of control over their eating, and experience distress, guilt, or embarrassment afterward.
• Pica: A condition characterized by eating non-food substances, such as dirt, clay, paper, or hair. People with pica may have nutritional deficiencies, mental health issues, or developmental disorders.
• Avoidant/restrictive food intake disorder (ARFID): A condition characterized by a lack of interest or aversion to food. People with ARFID may have difficulty eating certain foods due to sensory issues, fear of choking or vomiting, or lack of appetite. They may avoid eating in social situations or have trouble meeting their nutritional needs.
• Rumination disorder: A condition characterized by regurgitating and re-chewing food. People with rumination disorder may spit out or swallow the food again. They may do this intentionally or unconsciously and may have gastrointestinal problems, malnutrition, or dental erosion.
• Orthorexia: A condition characterized by an obsessive focus on healthy eating. People with orthorexia may follow strict rules or diets, avoid certain foods or food groups, and experience anxiety or guilt when they deviate from their regimen. They may also spend excessive time and money on food preparation and planning.

The following table summarizes the main features of these eating disorders:

Treatments for Eating Disorders

Eating disorders are treatable, but they require a comprehensive and multidisciplinary approach that addresses the physical, psychological, and social aspects of the condition. The treatment plan may vary depending on the type and severity of the disorder, the age and preferences of the person, and the availability of resources. Some of the possible treatments are:

• Medical care: Eating disorders can cause serious and potentially life-threatening health complications that require immediate attention and monitoring. Medical care may involve hospitalization, medication, nutritional supplements, or other interventions to stabilize the physical condition and prevent further damage.
• Nutritional counseling: Eating disorders can affect the nutritional status and needs of a person, as well as their relationship with food. Nutritional counseling may involve working with a dietitian or nutritionist to develop a personalized and balanced meal plan, restore weight and health, and improve eating behaviors and attitudes.

• Psychotherapy: Eating disorders can affect the mental and emotional well-being of a person, as well as their underlying causes and factors. Psychotherapy may involve working with a therapist or counselor to explore and address the thoughts, feelings, and behaviors related to the eating disorder, and to develop coping skills and strategies to overcome the challenges and improve the quality of life. Some of the common types of psychotherapy for eating disorders are:
  • Cognitive behavioral therapy (CBT): A type of therapy that focuses on identifying and changing the negative and distorted thinking patterns and beliefs that contribute to the eating disorder. CBT can help people recognize and challenge their unrealistic or harmful thoughts about food, weight, and body image, and replace them with more rational and positive ones.
  • Dialectical behavior therapy (DBT): A type of therapy that combines CBT with mindfulness and acceptance techniques. DBT can help people regulate their emotions, tolerate distress, and improve their interpersonal relationships. DBT can also teach people skills to cope with urges to binge, purge, or restrict, and to accept themselves and their bodies.
  • Interpersonal psychotherapy (IPT): A type of therapy that focuses on improving communication and interaction with others. IPT can help people identify and resolve the interpersonal problems or conflicts that may trigger or maintain the eating disorder. IPT can also help people enhance their self-esteem and social support.
  • Family-based therapy (FBT): A type of therapy that involves the participation of the family members or caregivers of the person with the eating disorder. FBT can help the family understand and support the person with the eating disorder, and to create a positive and healthy environment for recovery. FBT can also help the family address any issues or difficulties that may affect the family dynamics or functioning.
• Support groups: Eating disorders can make people feel isolated, misunderstood, or alone. Support groups can provide a safe and supportive space for people with eating disorders to share their experiences, feelings, and challenges with others who can relate and empathize. Support groups can also offer information, education, and resources to help people cope and recover from eating disorders. Support groups can be led by professionals or peers, and can be online or in-person.

Latest Trends and Updates on Eating Disorders

Eating disorders are constantly evolving and changing, as new research, evidence, and awareness emerge. Here are some of the latest trends and updates on eating disorders as of February 2024:

• COVID-19 pandemic: The COVID-19 pandemic has had a significant impact on the prevalence, severity, and treatment of eating disorders. The pandemic has increased the risk factors and triggers for eating disorders, such as stress, anxiety, isolation, boredom, loss of routine, and exposure to social media and online content. The pandemic has also disrupted the access and availability of health care and support services for people with eating disorders and has forced many to adapt to online or telehealth modes of delivery. The pandemic has also highlighted the need for more funding, research, and advocacy for eating disorders, as well as the importance of prevention and early intervention.
• Diversity and inclusion: Eating disorders can affect anyone, regardless of their age, gender, race, ethnicity, culture, sexual orientation, or socioeconomic status. However, historically, eating disorders have been stereotyped and stigmatized as a “white, female, and affluent” problem, which has led to the underrepresentation and marginalization of other groups and communities. Recently, there has been more recognition and awareness of the diversity and inclusion of eating disorders, and more efforts to address the specific needs and challenges of different populations, such as men, people of color, LGBTQ+ people, older adults, and people with disabilities. There has also been more research and evidence on the prevalence, presentation, and treatment of eating disorders among these groups, as well as more advocacy and activism to promote their voices and visibility.
• Technology and innovation: Technology and innovation have played a vital role in the advancement and improvement of the diagnosis, assessment, and treatment of eating disorders. Technology and innovation have enabled the development and implementation of new and novel tools and methods, such as mobile apps, wearable devices, online platforms, virtual reality, artificial intelligence, and machine learning. These technologies and innovations have the potential to enhance the accessibility, affordability, effectiveness, and personalization of eating disorder interventions, as well as to provide more data, feedback, and support for people with eating disorders and their providers. However, technology and innovation also pose some challenges and risks, such as ethical, legal, and privacy issues, quality and safety concerns, and digital divide and inequality.
