This hypothesis was supported by a recent genome-wide association study which reveled genetic correlations with metabolic traits in terms of regulation of insulin, glucose and lipid ( 13). Hypothetically, the same genetic factors that influence normal variation in BMI may also influence dysregulation of appetite and weight-related features in AN. Twin studies uniquely have supported a genetic origin for the observed familial accretion in AN.

But at the same time, it may maintain and intensify the anorexia, physical hyperactivity and amenorrhea, thus potentially creating a vicious circle, although the latter remains to be proven.

Hypersecretion of corticotropin-releasing hormone (CRH) is a response to starvation. For instance, hypothalamic amenorrhea is often secondary, but it can precede the weight loss and persist for a long time after weight and motor activity have returned to normal ( 12). The endocrine alterations can be adaptive, reactive or etiologic. However, since that the outcome may have improved with an evolutionary neuroscience approach to treatment ( 7).ĪN is associated with multiple, profound endocrine disturbances ( 8, 9, 10), and adaptation to chronic semi-starvation allows survival even with extreme emaciation ( 11). There was no evidence that the prognosis has improved throughout the 20th century ( 6). The evidence base for treatment is still very limited ( 5). Diagnostic boundaries, which are based on symptoms, may not reflect the underlying pathophysiological mechanisms.

The diagnostic criteria were revised in 2013 for the Fifth Edition of the Diagnostic and Statistical Manual ( 1), leading to markedly increased diagnostic heterogeneity and a 30–50% increase in lifetime prevalence ( 2, 3), which is estimated to be 1–4% ( 4). The severity varies from mild subclinical cases to chronic enduring and fatal cases. It is characterized by disturbed body image, ego-syntonic neglect, ambivalence, self-starvation, loss of body weight, obsessive thoughts of food, ritualistic patterns of food intake, elevated physical activity, depression, anxiety and emotional rigidity. Considering this, the aim of the present review is to provide an updated overview of the many endocrine changes in a clinical perspective.Īnorexia nervosa (AN) is a syndrome as it describes a collection of symptoms and is not defined by an etiology. A breakthrough in our understanding and treatment of this whimsical disease remains. We need reliable biomarkers for predicting outcome and to ensure safe re-nutrition, however, first of all we need them to explore the metabolism in anorexia nervosa to open new avenues with therapeutic targets. Besides well-established peripheral endocrine actions, several hormones also are released directly to different brain areas, where they may exert behavioral and psychogenic actions that could offer therapeutic targets.

An important focus of clinical research should be to identify biomarkers associated with different stages of weight loss and re-nutrition combined with psychometric data. Electrolyte levels must be closely monitored during the refeeding process, and the need for weight gain must be balanced against potentially fatal refeeding complications. Adaptive changes potentially may be inappropriate in clinical settings such as inpatient intensive re-nutrition or in a setting with somatic comorbidity. The syndrome is associated with multiple, profound endocrine alterations which may be adaptive, reactive or etiologic. Anorexia nervosa is a syndrome, that is collections of symptoms, which is not defined by its etiology.
