bulimia nervosa

Examples of bulimia nervosa in the following topics:

• Eating Disorders

  • Anorexia Nervosa (AN) is a serious psychiatric illness characterized by failure to maintain a minimally normal weight, intense fear of gaining weight or becoming fat, and preoccupations about body shape and weight .
  • Bulimia Nervosa (BN) is defined by the frequent episodic consumption of objectively large amounts of food and the use of compensatory behaviors to avoid weight gain.
  • Eating Disorders Not Otherwise Specified (EDNOS) is an eating disorder that does not meet the criteria for anorexia nervosa or bulimia nervosa, and includes binge eating disorder, night eating syndrome, and sub-threshold syndromes in which some, but not all, of the symptoms of the more formally defined eating disorders are present.
  • Eating disorders, such as anorexia nervosa shown in this picture, involve abnormal eating patterns which can affect both physical and mental health, including impairments in memory.
  • Differentiate between anorexia nervosa, bulimia nervosa, binge eating disorder, and eating disorder not otherwise specified (EDNOS), examining their causes and consequences

• Eating Disorders

  • There are four types of eating disorders that are recognized in the DSM-5: anorexia nervosa, bulimia nervosa, binge eating disorder, and eating disorder not otherwise specified (NOS).
  • Bulimia nervosa is characterized by recurrent binge eating followed by compensatory behaviors for the intake of food, such as purging.
  • Bulimia nervosa can be difficult to detect compared to anorexia nervosa, because people with bulimia tend to be of average or slightly above or below average weight.
  • Many people with bulimia may also engage in significantly disordered eating and exercising patterns without meeting the full diagnostic criteria for bulimia nervosa.
  • The binges must not be accompanied by compensatory purging behavior seen in bulimia nervosa.

• Feeding Disorders

  • This disturbance must not be due to unavailability of food; to observation of cultural norms; to anorexia nervosa, bulimia nervosa, or another eating disorder; to perceived flaws in one's body shape or weight; or to another medical condition or mental disorder.
  • Other forms of eating disorders, such as anorexia nervosa or bulimia nervosa, involve a fear of gaining weight; while those who suffer from ARFID do not have this specific fear, the psychological symptoms and resulting anxiety are similar.

• Nutrition and Health

  • Existing or incipient psychological conditions (e.g. eating disorders like anorexia and bulimia) can cause nutritional deficiency and result in poor physical health.

• The Biopsychosocial Model of Health and Illness

  • The impact of social factors is widely recognized in mental disorders like anorexia nervosa (a disorder characterized by excessive and purposeful weight loss despite evidence of low body weight).
