Qu\u2019est-ce que c\u2019est ?<\/strong><\/h3>\n

D\u00e9finie comme l\u2019\u00e9mission d\u2019au moins 3 selles non form\u00e9es par jour, la diarrh\u00e9e du voyageur est, le plus souvent, b\u00e9nigne, br\u00e8ve (< 5 jours) et gu\u00e9rit spontan\u00e9ment. Elle survient g\u00e9n\u00e9ralement lors de s\u00e9jours dans des r\u00e9gions o\u00f9 les conditions sanitaires et d\u2019hygi\u00e8ne sont pr\u00e9caires.<\/p>\n

Les causes et la pr\u00e9vention<\/strong><\/h3>\n

Lors d\u2019un voyage, les diarrh\u00e9es sont g\u00e9n\u00e9ralement caus\u00e9es par des bact\u00e9ries, mais aussi des virus ou des parasites. A noter que les d\u00e9calages horaires peuvent \u00eatre source de sympt\u00f4mes gastro-intestinaux. La pr\u00e9vention repose sur quelques r\u00e8gles hygi\u00e9no-di\u00e9t\u00e9tiques :<\/p>\n

    \n
  • Se laver les mains fr\u00e9quemment (imp\u00e9rativement avant\/apr\u00e8s les repas et en sortant des toilettes) pr\u00e9f\u00e9rentiellement \u00e0 l\u2019eau et au savon, ou avec du gel hydro-alcoolique.<\/li>\n
  • Boire uniquement l\u2019eau ou autre boisson provenant d\u2019une bouteille ouverte devant soi, ou utiliser des pastilles de d\u00e9sinfection de l\u2019eau.<\/li>\n
  • Ne pas consommer de glaces et de boissons contenant des gla\u00e7ons.<\/li>\n
  • Eviter de consommer les crudit\u00e9s, les fruits non lui-m\u00eame, les fruits de mer peu cuits ou crus, les produits laitiers non pasteuris\u00e9s, et la nourriture vendue dans la rue ou pr\u00e9sent\u00e9e en buffet.<\/li>\n<\/ul>\n

    Consommer la nourriture bien cuite et gard\u00e9e tr\u00e8s chaude (surtout les viandes, les poissons, les crustac\u00e9s et les \u0153ufs) et si possible non r\u00e9chauff\u00e9.<\/p>\n

    Les facteurs de risque<\/strong><\/h3>\n

    Des facteurs propres \u00e0 l\u2019h\u00f4te comme un traitement en cours (comme par exemple par un antihistaminique H2 contre l\u2019ulc\u00e8re), la quantit\u00e9 d\u2019agents pathog\u00e8nes vivants qui atteignent l\u2019intestin sont corr\u00e9l\u00e9s \u00e0 la probabilit\u00e9 de d\u00e9velopper une diarrh\u00e9e. Certaines populations sont particuli\u00e8rement vuln\u00e9rables : les enfants, les personnes \u00e2g\u00e9es, les femmes enceintes, les immunod\u00e9prim\u00e9s et les patients souffrant de pathologies gastro-intestinales chroniques ou de maladies sous-jacentes (diab\u00e8te, insuffisance cardiaque\u2026).<\/p>\n

    Le traitement<\/strong><\/h3>\n
      \n
    • Boire beaucoup d\u2019eau pour pallier la perte importante de liquide, en alternant les boissons sucr\u00e9es et sal\u00e9es. L\u2019alcool et la caf\u00e9ine aggravent la d\u00e9shydratation.<\/li>\n
    • Utiliser un SRO (solut\u00e9 de r\u00e9hydratation oral) si besoin, notamment pour les enfants.<\/li>\n
    • Le lop\u00e9ramide peut parfois \u00eatre associ\u00e9 mais il est contre-indiqu\u00e9 en cas de fi\u00e8vre ou de diarrh\u00e9e glairo-sanglante. Son administration doit \u00eatre interrompue en cas d\u2019aggravation des sympt\u00f4mes ou si la diarrh\u00e9e persiste plus de 2 jours.<\/li>\n
    • Associer une antibioth\u00e9rapie pour les formes s\u00e9v\u00e8res selon avis m\u00e9dical.<\/li>\n<\/ul>\n

      Quand consulter ?<\/strong><\/h3>\n

      Une consultation m\u00e9dicale s\u2019impose en cas de d\u00e9shydratation ne r\u00e9pondant pas \u00e0 la r\u00e9hydratation, fi\u00e8vre, pr\u00e9sence de sang dans les selles, fortes douleurs abdominales, vomissements, \u00e9tat g\u00e9n\u00e9ral alt\u00e9r\u00e9, et en l\u2019absence d\u2019am\u00e9lioration ou en cas d\u2019aggravation des sympt\u00f4mes sous 48 h. Elle est recommand\u00e9e syst\u00e9matiquement chez l\u2019enfant de moins de 2 ans.<\/p>\n","protected":false},"excerpt":{"rendered":"
