anorexia nervosa

Examples of anorexia 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).
  • Anorexia nervosa is characterized by extreme food restriction and excessive weight loss, accompanied by the fear of being fat.
  • Relative to the previous version of the DSM (DSM-IV-TR) the 2013 revision (DSM-5) reflects changes in the criteria for anorexia nervosa, most notably that of the amenorrhea criterion being removed.
  • 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.
  • The diagnosis is made only when the behavior is not a part of the symptom complex of anorexia nervosa and when the behavior reflects an overemphasis on physical mass or appearance.

• Female Athlete Triad: Disordered Eating, Amenorrhea, and Premature Osteoporosis

  • The disordered eating that accompanies female athlete triad can range from avoiding certain types of food the athlete thinks are "bad" (such as foods containing fat) to serious eating disorders like anorexia nervosa or bulimia nervosa.
  • While most athletes do not meet the criteria to be diagnosed with an eating disorder such as anorexia nervosa or bulimia nervosa, many will exhibit disordered eating habits.

• 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.

• Sodium, Electrolytes, and Fluid Balance

  • People suffering from bulimia or anorexia nervosa are especially at high risk for an electrolyte imbalance.

• 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).
  • For example, anorexia is less common in non-western cultures because they put less emphasis on thinness in women. 

• Raynaud's Phenomenon

  • Secondary Raynaud's has a number of associations such as connective tissue disorders, eating disorders such as anorexia nervosa, and obstructive disorders.

• The Posterior Pituitary

  • Pars nervosa, also called the neural lobe or posterior lobe, constitutes the majority of the posterior pituitary and is the storage site of oxytocin and vasopressin.

• Other Fungi Involved in Respiratory Disease

  • The symptoms include weight loss, anorexia, and the appearance of bony lesions.

• For each problem:

  • According to the South Carolina Department of Mental Health web site, for every 200 U.S. women, the average number who suffer from anorexia is one (http://www.state.sc.us/dmh/anorexia/statistics.htm 16 ).
