The 3 Most Common Eating Disorders and Their Impact on Health

All eating disorders are grave mental health conditions that correlate with significant disruptions in individuals’ eating patterns and associated thoughts and emotions. These complex mental health conditions affect people of all ages and genders, and their consequences can be severe and often fatal.

This article will explore the three most common eating disorders—anorexia nervosa, bulimia nervosa, and binge-eating disorder. By understanding their characteristics, causes, and potential treatments, we can promote awareness and support those affected by these disorders.

Anorexia Nervosa

Anorexia nervosa is perhaps the most well-known eating disorder. Individuals with anorexia nervosa have an intense fear of gaining weight, leading them to restrict their food intake severely. They may also engage in excessive exercise and have distorted body image perceptions. This disorder predominantly affects young women, but it can occur in males as well.

Causes of anorexia

The causes of anorexia nervosa are multifactorial, including genetic, environmental, and psychological factors. Social pressures, perfectionism, low self-esteem, and traumatic life experiences may contribute to the development of this disorder. Anorexia nervosa can have severe health consequences, such as malnutrition, electrolyte imbalances, cardiac issues, and osteoporosis.

Identifying the Signs of Anorexia Nervosa

  • Extreme weight loss: Individuals with anorexia nervosa often exhibit significant and rapid weight loss, resulting from severe calorie restriction and excessive exercise.
  • Obsession with body weight and shape: They may have an excessive preoccupation with body weight, engage in constant body checking, and express intense dissatisfaction with their appearance.
  • Restrictive eating patterns: Anorexia nervosa is characterized by rigid food restrictions, avoidance of certain food groups, and rituals surrounding mealtime.
  • Distorted body image: People with anorexia nervosa often have a distorted perception of their own body, seeing themselves as overweight even when they are underweight.
  • Physical symptoms: Common physical signs include fatigue, dizziness, low blood pressure, thinning hair, brittle nails, and cold intolerance.

Treatment for anorexia nervosa

Treatment for anorexia nervosa often involves a multidisciplinary approach, including medical, nutritional, and psychological interventions. Therapy aims to address the underlying psychological issues, establish healthy eating patterns, and promote a positive body image.


Bulimia Nervosa


Bulimia nervosa is characterized by recurrent episodes of binge eating, followed by compensatory behaviors such as self-induced vomiting, excessive exercise, or the use of laxatives. Unlike anorexia nervosa, individuals with bulimia nervosa often maintain a normal or slightly above-average body weight, which can make the disorder less apparent to others.

Causes of bulimia nervosa

The causes of bulimia nervosa are similar to those of anorexia nervosa, with a combination of genetic, environmental, and psychological factors playing a role. Factors such as societal pressure for thinness, low self-esteem, and emotional distress may contribute to the development of this disorder. Bulimia nervosa can result in various health complications, including electrolyte imbalances, dental issues, gastrointestinal problems, and depression.

Identifying the Signs of Bulimia Nervosa

  • Frequent episodes of binge eating: Individuals with bulimia nervosa often experience episodes of consuming large amounts of food within a short period, accompanied by a loss of control.
  • Compensatory behaviors: After a binge-eating episode, individuals may engage in compensatory behaviors such as self-induced vomiting, excessive exercise, or misuse of laxatives or diuretics.
  • Fluctuations in weight: People with bulimia nervosa may have weight fluctuations due to the cycle of bingeing and purging, which can be noticeable.
  • Preoccupation with body shape and weight: A strong preoccupation with body shape, weight, and appearance is common in individuals with bulimia nervosa.

Treatment for bulimia nervosa

The treatment for bulimia nervosa usually involves a combination of therapies, such as cognitive-behavioral therapy (CBT), which helps individuals identify and change unhealthy thoughts and behaviors. Nutritional counseling and medication may also be incorporated into the treatment plan to address the physical and emotional aspects of the disorder.


Binge-Eating Disorder


Binge-eating disorder is defined by recurring episodes of consuming large quantities of food within a short period, accompanied by a feeling of loss of control. Unlike bulimia nervosa, individuals with binge-eating disorders do not engage in compensatory behaviors, like purging. This disorder affects both men and women and can occur at any age.

Binge-eating disorder, is the most common eating disorder, even though is not nearly as known as anorexia or bulimia.

Causes of binge-eating disorder

The exact causes of binge-eating disorder are not fully understood, but genetics, psychological factors, and cultural influences are believed to contribute to its development. Emotional distress, such as stress, depression, or trauma, may also play a role. Binge-eating disorder can lead to obesity, high blood pressure, heart disease, and psychological distress, including shame and guilt.

Identifying the Signs of Binge-Eating Disorder

  • Frequent episodes of binge eating: Individuals with binge-eating disorder often have recurrent episodes of consuming excessive amounts of food, even when not physically hungry, resulting in discomfort and distress.
  • Eating rapidly and to discomfort: During binge-eating episodes, people may eat rapidly, feeling like they can’t control or stop their eating until they are uncomfortably full.
  • Emotional distress: Binge eating is often accompanied by feelings of guilt, shame, and embarrassment. Individuals may eat in secret to avoid judgment or criticism.
  • Lack of compensatory behaviors: People with binge-eating disorders do not engage in compensatory behaviors like vomiting or excessive exercise.

Treatment for binge-eating disorder

The treatment for binge-eating disorder often involves a combination of therapy, such as CBT or interpersonal psychotherapy, to address the underlying emotional issues and establish healthy eating habits. Support groups and medication may also be utilized to aid in recovery.
