Definition
Eating disorders are not lifestyle choices, as they are often mistakenly believed to be. They are serious mental health disorders that affect eating behaviors and can be life-threatening.
Eating disorders may be indicated by:
- Significant changes in body weight
- Positive or negative obsessions with food
- Disordered eating behaviors
Some of the most common eating disorders include:
- Anorexia Nervosa
- Bulimia Nervosa
- Binge-Eating Disorder
Signs and Symptoms
Anorexia Nervosa
Anorexia Nervosa is primarily centered on distorted body image. Individuals with this disorder often perceive themselves as overweight, even when they are underweight. A common behavioral trait is repeated or obsessive weighing.
Because of this distorted self-perception, individuals may:
- Severely restrict food intake
- Eat only very small amounts of food
- Limit themselves to specific types of food
Anorexia Nervosa has the highest mortality rate of all mental health disorders. Death most commonly results from starvation-related complications, though suicide risk—particularly among women—is also significant.
Acute Symptoms
- Severely restricted eating behaviors
- Extreme thinness or emaciation
- Obsessive focus on weight and thinness
- Inability to maintain a healthy body weight
- Intense fear of gaining weight
- Distorted self-image
- Self-worth tied closely to body shape or weight
- Denial of the seriousness of low body weight
Long-Term or Progressive Symptoms
- Osteopenia or osteoporosis
- Mild anemia
- Muscle weakness and wasting
- Brittle hair and fingernails
- Dry or yellowing skin
- Growth of fine body hair
- Chronic constipation
- Heart structure and function damage
- Brain damage
- Organ failure
- Lowered body temperature and constant feeling of cold
- Persistent fatigue, lethargy, or sluggishness
- Loss of reproductive fertility
Bulimia Nervosa
Bulimia Nervosa is characterized by recurrent episodes of binge eating, during which large amounts of food are consumed with a sense of loss of control. These episodes are followed by compensatory behaviors, such as:
- Self-induced vomiting
- Use of laxatives or diuretics
- Excessive exercise
- Fasting
Unlike anorexia, individuals with bulimia often maintain a normal or near-normal body weight, which can make the disorder more difficult to detect.
Common Symptoms
- Chronic sore or inflamed throat
- Swelling of the salivary glands in the neck or jaw
- Worn tooth enamel and increased tooth sensitivity
- Dental decay from repeated exposure to stomach acid
- Acid reflux, GERD, or other gastrointestinal issues
- Abdominal pain or bowel complications from laxative misuse
- Dehydration
- Electrolyte imbalances that may lead to stroke or heart attack
Binge-Eating Disorder
Binge-Eating Disorder is defined by repeated episodes of uncontrolled eating without the compensatory behaviors seen in bulimia.
Individuals with this disorder often consume large amounts of food even when not physically hungry and may eat to the point of discomfort. Binge-Eating Disorder is the most common eating disorder in the United States.
People with binge-eating disorder are often overweight or obese, though this is not always the case.
Typical Symptoms
- Eating unusually large amounts of food in a short time
- Eating despite feeling full
- Eating when not hungry
- Rapid eating
- Eating until uncomfortably full
- Eating alone or in secret
- Feelings of guilt, shame, or distress after eating
- Frequent dieting without significant weight loss
Risk Factors
Eating disorders most commonly develop during the teenage years, though they can occur in childhood or later adulthood.
While both men and women experience eating disorders, women are more than twice as likely to be affected.
Additional risk factors include:
- Distorted body image perceptions
- Societal or cultural pressures related to appearance
- Focus on thinness (more common in women) or muscularity (more common in men)
The development of eating disorders is complex and typically involves a combination of:
- Genetic factors
- Biological influences
- Psychological factors
- Social and environmental pressures
Treatments and Therapies
Effective treatment for eating disorders focuses on both physical recovery and psychological healing. A critical component of treatment is restoring and maintaining a healthy body weight while developing sustainable, healthy eating behaviors.
Treatment plans may include one or more of the following:
- Individual psychotherapy
- Family-based therapy
- Medical monitoring and intervention
- Nutritional counseling
- Cognitive Behavioral Therapy (CBT)
- Psychodynamic therapy
- Crisis intervention
- Psychoanalysis
Early diagnosis and a comprehensive, individualized treatment plan significantly improve outcomes.
