Anorexia and Binge-Purge Cycles: Unraveling the Distinct Characteristics
It's noteworthy that some afflicted by anorexia may engage in binge-purge cycles akin to bulimia, yet the prevailing characteristic remains an unnaturally low body weight, distinguishing them from their bulimic counterparts who often maintain normal to above-normal weights.
Causes of Anorexia Nervosa
The exact causes of AN are not fully understood, but they are likely to involve a complex interaction of biological, psychological, and environmental factors.
Some of the possible factors are:
Genetics
Some people may have a genetic predisposition to AN, especially if they have a family history of eating disorders or other mental health conditions.
Hormones
Hormonal imbalances, such as low levels of estrogen or thyroid hormones, may affect appetite, metabolism, and mood, and increase the risk of developing AN.
Emotions
AN may be a way of coping with negative emotions, such as stress, trauma, anger, sadness, loneliness, or guilt.
People with AN may have difficulty expressing and regulating their emotions, and may use food as a source of comfort, control, or punishment.
Cognition
AN may be influenced by distorted thoughts and beliefs about food, weight, and shape, such as “I must be thin to be happy”, “I am a failure if I eat too much”, or “I can’t stop eating once I start”.
These thoughts may trigger or reinforce AN behaviors and create a vicious cycle of self-criticism and low self-esteem.
Environment
AN may be affected by external factors, such as the availability and accessibility of food, social pressure, cultural norms, media messages, or traumatic events.
These factors may increase one’s exposure to food cues, expectations, or stressors, and may influence one’s eating habits and attitudes.
Treatment of Anorexia Nervosa
AN is a treatable condition, but it requires a comprehensive and multidisciplinary approach that addresses the physical, psychological, and social aspects of the disorder.
The main goals of treatment are to restore a healthy weight, normalize eating patterns, correct nutritional deficiencies, improve physical and mental health, and prevent relapse. Some of the possible treatment options are: 67
Medical care
Medical care is essential to monitor and manage the physical complications of AN, such as dehydration, electrolyte imbalance, heart problems, or organ failure.
Medical care may also involve the use of medication, such as antidepressants, antipsychotics, or appetite stimulants, to treat underlying or co-occurring mental health conditions, such as depression, anxiety, or obsessive-compulsive disorder.
Nutritional counseling
Nutritional counseling is a form of education and guidance that aims to help restore a balanced and adequate diet and to normalize eating patterns and behaviors.
A registered dietitian can provide nutritional counseling and tailor a meal plan according to one’s individual needs and preferences.
Nutritional counseling may also involve the use of supplements, such as vitamins, minerals, or electrolytes, to correct nutritional deficiencies and support health.
Psychological therapy
Psychological therapy is a form of counseling that aims to help understand and change the underlying causes and consequences of AN, and to develop healthier coping skills, self-image, and emotional regulation.
There are different types of psychological therapy for AN, such as cognitive-behavioral therapy (CBT), dialectical behavior therapy (DBT), interpersonal therapy (IPT), family-based therapy (FBT), or focal psychodynamic therapy (FPT).
Psychological therapy may be delivered individually, in groups, or with family members or carers, depending on the needs and preferences of the person with AN.
Support groups
Support groups are a form of peer support that aims to provide a safe and supportive environment for people who share similar experiences and challenges with Anorexia Nervosa.
Support groups can reduce isolation, increase insight and perspective, and receive encouragement and feedback from others. Support groups can be either online or in-person, and can be led by a professional or a peer.
