The eating illness known as anorexia nervosa is characterized by a reduction in caloric intake compared to needs, which results in noticeably low body mass. Patients who are unable to comprehend the gravity of their very low body fat will experience distorted body image, extreme anxiety about gaining weight, and body dysmorphia.
Epidemiology
Females are more likely than guys to suffer from anorexia nervosa. Young adulthood and late youth are the times of onset. Regardless of ethnicity, color, or culture, the lifetime prevalence is 0.3 percent to one percent (European research has shown a prevalence of two percent to four percent).
Child obesity, mood disturbances, female sex, personality qualities (perfectionism and impulsivity), sex assault, or weight-related worries from peer or familial surroundings are risk factors for disordered eating.
Anatomy
Pathophysiology
Studies show that in addition to environmental variables, genetic factors also play a part in the development of anorexia nervosa. There are genetic links between neuroticism, schizophrenia, and education level.
Dopamine (which regulates dietary habits & rewards) & serotonin (which regulates impulsivity & neuroticism) deficits, differential stimulation of the corticolimbic framework (which regulates appetite and fear), & habitual behaviors (decreased activity) among the frontostriatal circuits are all symptoms of anorexia nervosa.
Co-occurring mental diseases in patients include major depression & generalized anxiety disorder, among others.
Etiology
Numerous professions rely on a person’s weight for success. Models & performers present a level of slimness that is challenging to achieve; make-up & photographic manipulations enhance this image.
Ballet dancers, marathon runners, & martial artists all face pressure to keep lean body compositions in order to perform better than their rivals.
Media outlets frequently advertise weight-loss strategies & dietary secrets. Populations like mature females associate losing weight with self-control & associate slender body types with higher self-esteem.
Genetics
Prognostic Factors
In AN, remission can vary. In outpatient clinical settings, three-fourths of individuals remit after five years, and the same proportion has intermediate-good results (such as weight gain). Patients with co-morbid psychiatric problems, lower body fat/weight at the end of treatment, older age groups with longer disease durations, and those who receive therapy outside of specialized clinics are more likely to relapse.
Patients who experience limited remission frequently acquire new eating disorders (ex., unspecified eating disease or bulimia nervosa). Compared to the general population, AN had higher rate of all-cause fatality. Among all disordered eating, it has one of the higher fatality rates because of health issues, drug misuse, & suicide. Suicide is more common in AN patient, and it accounts for 25 percent of related deaths.
