Study Notes

Eating Disorders and Disordered Eating

Eating disorders are psychological disturbances that lead to abnormal physiological changes and dangerous health complications.
Disordered eating is chaotic and abnormal food-related practices, such as skipping meals, limiting food choices, following fad diets, and bingeing on food.
Disordered eating behaviors can become harmful and lead to serious eating disorders if adopted as a lifestyle.

Major Types of Eating Disorders

Three main types of eating disorders: Anorexia Nervosa (AN), Bulimia Nervosa (BN), and Binge-Eating Disorder (BED).
AN is characterized by self-imposed starvation that results in malnutrition and very low body weight.
BN is characterized by repeated episodes of binge eating followed by purging, such as self-induced vomiting, to prevent weight gain.
BED is characterized by recurrent episodes of overeating that are not followed by purging behaviors.

Risk Factors for Eating Disorders

Being female
Having a poor self-image
Having low self-esteem and a perfectionist personality
Being in a dysfunctional family environment
Being teased about weight
Being in an occupation or sport that emphasizes a lean body build
Genetic and biological factors
Psychological and personality factors
National origin, income level, occupation, and lifestyle choices

Anorexia Nervosa (AN)

Characterized by self-imposed starvation that results in malnutrition and very low body weight.
Symptoms include distorted body image, excessive exercising, and severe restriction of food intake.
Health consequences include severe constipation, slow heart rate, hypotension, loss of normal menstrual cycles, and low bone mineral density.
Highest mortality rate of any psychological disorder, with 6% of people with AN eventually dying as a result of the disorder.

Bulimia Nervosa (BN)

Characterized by repeated episodes of binge eating followed by purging, such as self-induced vomiting, to prevent weight gain.
Symptoms include binge eating, purging, and excessive exercising.
Health consequences include erosion of tooth enamel, dental caries, and gastrointestinal problems.
Associated with low self-esteem, depression, and anxiety disorders.

Binge-Eating Disorder (BED)

Characterized by recurrent episodes of overeating that are not followed by purging behaviors.
Symptoms include eating large amounts of food when not hungry, eating rapidly, and feeling guilty or ashamed after eating.
Health consequences include obesity, type 2 diabetes, and cardiovascular disease.
Associated with depression, anxiety, and substance abuse disorders.

Other Unhealthy Eating Behaviors

Night Eating Syndrome (NES): episodic food binges that occur at night or after the evening meal.
Diabulimia: skipping insulin injections or using less insulin than prescribed to manipulate body weight.
Muscle Dysmorphia: an unhealthy preoccupation with the body being too small or not muscular enough.
The Athlete Triad: characterized by three interrelated components: low energy availability, abnormal reproductive system function, and reduced bone mineral density.### Athlete Triad
Lack of estrogen during adolescence can lead to poor bone mineral density in female athletes, even after recovery from the triad.
Premature osteoporosis is a serious and long-term consequence of the athlete triad.

Male Athlete Triad

Male athletes may develop the male athlete triad, characterized by low energy availability, abnormal reproductive function, and reduced bone mineral density.
Male athletes at risk of developing the triad include those who participate in sports that benefit from a lower body weight, such as distance runners and cyclists, and those who need to "make weight" to compete in a lower weight class, such as wrestlers and boxers.
Normal testosterone levels are necessary for men to build and maintain bone mineral mass.
Male athletes with low testosterone levels may have reduced bone mineral density, increasing their risk of bone fractures.

Preventing Eating Disorders

Early identification of people with risk factors for eating disorders, such as disordered eating patterns and distorted body images, can help prevent the development of eating disorders.
Prevention efforts focus on fostering body acceptance, improving self-confidence, and challenging the idea that being thin is ideal.

Treating Eating Disorders

If someone has an eating disorder, it is important to encourage them to seek help as soon as possible to avoid serious health consequences.
Treatment should include psychotherapy, addressing critical nutritional needs, and other medical conditions.
Registered Dietitian Nutritionists (RDNs) play a critical role in assessing and treating eating disorders, including providing nutritional counseling.
Treatment can occur in inpatient, residential, or outpatient care settings, and may involve individual, group, or family counseling, as well as prescription medications.
Cognitive behavioral therapy (CBT) is a major treatment approach for bulimia nervosa (BN) and binge eating disorder (BED).
CBT teaches people healthy coping strategies to use when under stress instead of unhealthy behaviors.
