Abstract

The etiopathogenesis of eating disorders (ED) is complex and poorly understood. Biological, psychological and environmental factors have all been considered to be involved in the onset and the persistence of these syndromes, often with conflicting results. The recent literature focused on the possible role of hormonal pathways, in particular the hypothalamic-pituitary-adrenal (HPA) axis, as a relevant factor capable of influencing the onset and the course of ED. Other studies have suggested that the onset of ED is often preceded by severe life events, and that chronic stress is associated with the persistence of these disorders. As the biological response to stress is the activation of the HPA axis, the available literature considering the relationships between stress, HPA axis functioning and anorexia nervosa, bulimia nervosa and binge eating disorder is reviewed by the present article.

  • Many psychiatric disorders, including ED, PTSD, and anxiety disorders, are characterised by dysregulation of the HPA axis.

    “Since many psychiatric disorders, including ED, PTSD, and anxiety disorders, are characterised by dysregulation of the HPA axis (Connan et al., 2007;Ehlert et al., 2001;Lo Sauro et al., 2008), there has been increasing interest in further exploration of the potential anti-stress and anxiolytic effects of intranasal oxytocin in psychiatric disorders characterised by elevated threat sensitivity.”
  • The effects of gut bacteria on behavior are primarily mediated by their actions on the hypothalamic-pituitary-adrenal axis, which is fundamental to the etiology and progression of eating disorders.

    “The effects of gut bacteria on behavior are primarily mediated by their actions on the hypothalamic–pituitary–adrenal (HPA) axis, a major neuroendocrine system that regulates the response to both psychological and physical stressors and is fundamental to the etiology and progression of eating disorders [55].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
