Pour ce faire, ils évitent de manger certains aliments, contrôlent rigoureusement leur apport en calories et, parfois, adoptent des régimes d’exercices excessifs, utilisent des pilules ou se font vomir pour perdre du poids (un comportement appelé purge).</p> <p>À cause de leur image corporelle déformée, les personnes anorexiques peuvent se dire trop grosses, peu importe leur poids réel, et avoir peur de prendre du poids et de devenir grosses.</p><h2>À retenir</h2> <ul> <li>L’anorexie est un trouble du comportement alimentaire et de santé mentale caractérisé par une perception déformée de son image corporelle et une sous-alimentation afin de maintenir un poids insuffisant et malsain.</li> <li>Les anorexiques contrôlent leur poids en évitant de manger certains aliments, en calculant rigoureusement leur apport en calories et, parfois, en adoptant des régimes d’exercices excessifs ou en utilisant des pilules pour perdre du poids.</li> <li>Le déclenchement de l’anorexie peut être associé à un ensemble de facteurs sociaux et d’événements stressants de la vie alliés à la génétique.</li> <li>L’anorexie frappe le plus souvent les filles âgées de 13 à 15 ans, mais dans les années récentes, ce trouble alimentaire est en hausse chez les garçons et les jeunes enfants.</li> </ul><h2>Quelles sont les causes de l’anorexie?</h2> <p>Les causes exactes de l’anorexie sont inconnues. En règle générale, son déclenchement peut être associé à un ensemble de facteurs sociaux et d’événements stressants de la vie alliés à la génétique.</p> <h3>Facteurs sociaux</h3> <p>La participation à des activités qui accentuent l’importance de la minceur, voire la gymnastique et la carrière de mannequin, peuvent favoriser le déclenchement de l’anorexie. D’autres facteurs sociaux sont la pression exercée par les pairs pour s’intégrer et l’importance accordée dans les médias à une très faible gamme de types corporels idéaux, tels la minceur ou une apparence très musclée.</p> <h3>Événements stressants de la vie</h3> <p>L’anorexie peut être déclenchée par un sentiment de manque de maîtrise sur sa propre vie, surtout pendant ou après un événement stressant. Les personnes qui en souffrent tenteront de contrôler leur apport en calories en surveillant de façon excessive ce qu’elles mangent ainsi que leur poids. Il s’agit pour elles d’un moyen de reprendre la maîtrise perçue de leur situation quand d’autres aspects de leur vie leur semblent incontrôlables.</p> <h3>Génétique</h3> <p>Le fait d’avoir un membre de la parenté chez qui un trouble alimentaire a été diagnostiqué peut être un facteur de risque dans le déclenchement de l’anorexie. Lorsque l’anorexie est présente, il est aussi fréquent de trouver des antécédents familiaux de <a href="/Article?contentid=270&language=French">tr​oubles anxieux​</a>.</p> <h2>Qui est atteint d’anorexie?</h2> <p>L’anorexie frappe le plus souvent les filles adolescentes âgées de 13 à 15 ans, cette affection peut se déclarer à tout âge. Dans les années récentes. l’anorexie et les autres troubles du comportement alimentaire sont à la hausse chez les garçons et les jeunes enfants.</p><h2>En savoir plus</h2><p>Pour plus d’informations sur l’anorexie, veuillez consulter les pages suivantes :</p><p> <a href="/Article?contentid=269&language=French">Anorexie: signes avant-coureurs</a></p><p> <a href="/Article?contentid=267&language=French">Anorexie: complications médicales</a></p><p> <a href="/Article?contentid=700&language=French">Anorexie: options de traitement</a></p><p> <a href="/Article?contentid=266&language=French">Anorexie: comment aider votre enfant à la maison​</a></p><h2>Ressources</h2><p> <a href="http://www.nedic.ca/" target="_blank">NEDIC – Centre d’information sur les troubles alimentaires</a> (Canada)</p><p> <a href="https://www.nationaleatingdisorders.org/">NEDA – Association nationale des troubles alimentaires</a> (États-Unis)</p><p>L'académie américaine de pédiatrie – <em> <a href="https://www.healthychildren.org/English/health-issues/conditions/emotional-problems/Pages/Is-Your-Teen-at-Risk-for-Developing-an-Eating-Disorder.aspx" target="_blank">​Eating Disorders in Children</a></em></p><p> <a href="https://www.beateatingdisorders.org.uk/" target="_blank">BEAT – Lutter contre les troubles alimentaires</a> (Royaume Uni)</p><p> <a href="https://keltyeatingdisorders.ca/" target="_blank">Troubles alimentaires Kelty</a> (Centre de ressources sur la santé mentale Kelty, Hôpital pour enfants de la Colombie-Britannique)</p><p>Le Centre hospitalier pour enfants de l’est de l’Ontario – <a href="https://www.cheo.on.ca/fr/troubles_alimentaires_info" target="_blank"> <em>Eating Disorders​</em></a></p>
