Eating Disorders and Their Common Types

Eating disorders are severe conditions related to persistent eating behaviors that negatively impact physical health, mental well-being, and everyday functioning.

According to the National Eating Disorders Collaboration in Australia, approximately 9% of the Australian population is affected by eating disorders.

Other Eating Disorders

Several lesser-known eating disorders like Night Eating Syndrome and Selective Eating Disorder, among others.

Causes of Eating Disorders

  • Common Signs: Frequent regurgitation of food, re-chewing or spitting out food, and a lack of nausea before regurgitating.

  • Common Symptoms: Recurrent episodes of regurgitation without a nauseous feeling or retching.

  • Age and Sex Demographics: Primarily occurs in infants and young children but can occur at any age. The disorder is not strongly associated with any particular gender.

  • Health Concerns and Risks: Malnutrition, weight loss, and electrolyte imbalance are potential risks, along with dental erosion and bad breath.

The causes of eating disorders are complex and multifactorial, often arising from a combination of biological, psychological, and environmental factors. Body image plays a significant role, with societal pressures to attain a particular body shape or size driving some individuals toward disordered eating. This can be further fueled by exposure to idealized images in media and an intense fear of gaining weight or changing body shape.

Certain groups of people are at higher risk for developing eating disorders, including adolescents, athletes, and those with a family history of mental health issues. Other risk factors include experiencing trauma, high levels of stress, or belonging to cultural groups where thinness is highly valued.

It’s crucial to understand that while these factors might contribute, they are not the sole cause. Eating disorders can affect anyone, regardless of age, sex, or background.

Cognitive factors such as low self-esteem, perfectionism, and body dissatisfaction can also act as triggers, leading individuals down a dangerous path of distorted body image and unhealthy eating habits.

Biological factors, including hormonal imbalances and genetic predispositions, may also play a role. Some studies indicate that eating disorders have a genetic component, making individuals with a family history more susceptible. However, genetics alone don’t explain the onset; environmental triggers are usually involved. The nuanced nature of these causes makes it challenging to pinpoint a single reason why someone may develop an eating disorder. However, understanding the various contributing factors can aid in early identification and intervention, which is crucial for eating disorder recovery.

Diagnosing Eating Disorders and Mental Disorders

Eating disorders often co-occur with mental disorders like depression, anxiety, and obsessive-compulsive disorder. This makes diagnosis and treatment a bit more complicated, as both the eating disorder symptoms and mental health symptoms need to be addressed for effective treatment and recovery. A comprehensive assessment usually involves physical examinations, mental health evaluations, and diagnostic tests to rule out other underlying issues.

Getting an accurate diagnosis is crucial for effective treatment. If you suspect you or someone you know is struggling with an eating disorder, it’s essential to consult with healthcare professionals for a full evaluation. This evaluation usually involves a team of experts, including psychologists, dietitians, and medical doctors, who can provide a well-rounded view and create an individualized treatment plan.

Further complicating the diagnostic process is the fact that symptoms of eating disorders can often mask or exacerbate the symptoms of other mental disorders and vice versa. For example, the fatigue and lack of concentration associated with depression could be mistaken as side effects of severe weight loss from an eating disorder. Additionally, the secrecy and shame often surrounding eating disorders can make individuals less likely to seek help, delaying diagnosis and treatment.

Assessment tools like questionnaires and interviews can help professionals get a clearer picture of the disorder’s impact on an individual’s daily life, which is crucial for diagnosis. Medical tests such as blood tests, bone density scans, and heart checks may also be necessary to evaluate the physical toll the disorder has taken on the body. Psychological assessments, including discussions about eating habits, thought patterns, and emotional well-being, are also crucial to the diagnostic process.

In some cases, a person may have more than one type of eating disorder, or their symptoms may not meet the full criteria for diagnosis but are nonetheless distressing and disruptive. This condition is known as “Other Specified Feeding or Eating Disorder” (OSFED), and it requires specialized treatment like any other diagnosed eating disorder.

All these complexities highlight the importance of multidisciplinary care in diagnosing and treating eating disorders and accompanying mental health conditions. Individuals can only get the targeted help they need for recovery through a comprehensive approach.

Eating Disorder Treatments

Treatment for eating disorders is as varied as the types of disorders themselves and often involves a multidisciplinary approach. The mainstay of treatment is usually a combination of psychotherapy, nutritional education, and sometimes medication.

Cognitive-behavioral therapy (CBT) is often effective for conditions like anorexia nervosa and bulimia nervosa. On the other hand, medications like antidepressants can be useful in treating underlying mental disorders that may contribute to the eating disorder. Nutritional counseling helps individuals establish healthy eating habits and reverse the effects of malnutrition or weight gain.

Some eating disorders, such as binge eating disorder and rumination disorder, may require additional or alternative treatments like mindfulness training or medications that help control the impulse to eat. No one-size-fits-all treatment exists, and it often takes time to find the right mix of therapies that work for an individual.

Helping Someone Overcome an Eating Disorder

If you suspect someone you know is struggling with an eating disorder, approaching the topic requires sensitivity, compassion, and care. Open the lines of communication, but avoid making accusatory or judgmental statements that could put the person on the defensive. Instead, express your concerns using “I” statements, like “I’m concerned about your health because I’ve noticed you’ve been skipping meals.”

However, it’s crucial to know what not to do. Avoid discussing food, weight, or body shape, as these topics can be triggering and counterproductive. Please don’t force them to lose weight or eat or prevent them from eating, as this could exacerbate their disorder. Eating disorders affect the lives of people both directly and indirectly.

Remember, you’re not a healthcare provider, and while your support is vital, professional help is often necessary for recovery from an eating disorder. Please encourage them to seek qualified medical advice for an accurate diagnosis and treatment plan.

Treatment Options for Eating Disorders

Treatment for eating disorders typically involves a multi-pronged approach to address these complex conditions’ physical and psychological aspects. Over the years, various treatment modalities like psychotherapy, family-based treatments, and nutritional education have shown promising results.

However, it’s essential to note that the success of these treatments can vary from person to person. Some individuals may respond well to a particular treatment approach, while others may find it ineffective or even triggering, posing challenges to healthcare providers in offering personalized care.


Psychotherapy, particularly Cognitive Behavioral Therapy (CBT), is often the cornerstone of eating disorder treatment. It helps individuals understand the thought patterns leading to disordered eating and equips them with coping mechanisms.

The numerous benefits include improved self-esteem and a healthier relationship with food.

However, one drawback could be that psychotherapy is often a long-term commitment and may be costly. Finding the right therapist can be a trial-and-error process, which can be discouraging.

Family Approach

Involving the family in treatment, especially for adolescents, can be extremely beneficial. The family approach aims to educate everyone about eating disorders to create a supportive environment.

Family members learn how to encourage healthy eating habits and avoid triggers.

However, this approach might only be suitable for some. In some cases, family dynamics could contribute to the eating disorder, and involving family in the immediate treatment could be counterproductive.

Nutritional Education

Nutritional education is crucial for teaching individuals about healthy eating habits, portion control, and the importance of balanced nutrition. Registered dietitians often play a role in this education, providing practical tools like meal plans.

The benefits are straightforward: better physical health and a less distorted view of food. However, more than nutritional education is needed for long-term recovery by addressing the underlying psychological issues.

Also, the “dos and don’ts” could become new rules for those with obsessive tendencies, complicating their relationship with food.


Pharmacotherapy can be a supplementary line of treatment for eating disorders. For example, antidepressants are sometimes prescribed for patients with bulimia nervosa to help manage symptoms of depression or anxiety that may coexist.

Antipsychotics may also be used for severe cases of anorexia nervosa. Medication can be particularly helpful for treating the comorbid mental disorders often accompanying eating disorders. However, medications come with their risks, including side effects like weight gain or loss, which can be triggering for those dealing with eating disorders.

Furthermore, medication alone seldom addresses the underlying issues and is most effective with other treatments like psychotherapy.

Stepped Care Programs

Stepped care programs are tailored treatment plans that evolve according to the patient’s needs. Initially starting with less intensive treatments like outpatient therapy, the program intensifies to include more comprehensive approaches if no progress is observed.

This flexible model allows for personalized, adaptive care and is often more cost-effective. However, the risk lies in potentially underestimating the severity of the condition at the outset, leading to inadequate initial treatment. Some individuals may also find the escalation in treatment levels stressful.

Getting Professional Care

Seeking professional help is a crucial step towards recovery from an eating disorder. Professionals in the field have the expertise to diagnose and treat these complex issues accurately.

They offer a range of treatment options, from psychotherapy to medication and nutritional education, to provide comprehensive care. The benefits of professional care are multi-fold: faster diagnosis, tailored treatment plans, and a supportive environment for recovery.

Numerous success stories attest to the effectiveness of professional intervention. For instance, many people who have undergone Cognitive Behavioral Therapy report significant improvements in their eating habits and overall mental well-being.

Others who have been part of family-based treatment programs have seen their entire family dynamic shift towards more supportive and understanding relationships. Thus, professional care provides hope and a viable pathway to recovery.
