Reisandi diarrea: hvat forhindrar tað

Profylaxis virkar minni væl enn produktini vísa, og at vita hvat man skal gera tá tað hendir er meira týdningarmikið enn at forða tí.

Hvat profylaxis nýtir

Meta-analysur av probiotisk profylaxis [1][3][4] og av probiotikum samanborið við rifaximin [2] finna modest minkan í tíðini. Modest er tað týdningarmikla orðið: hetta eru relatívar vanda-minkingar í einum vanligum tilburði, ikki vernd.

Antibiotisk profylaxis er vanliga ikki tilmælt fyri vanlig ferðafólk. Tað drivur mótstøðu, hevur bíðivirkningar, og fremur kolonisering við mótstøðuførum organismum sum ferðafólk so taka heim — ein kostnaður fyri samfelagið, sum er goldin fyri ein persónligan fyrimun.

Profylaxis fyri ferðafólksdiaré

Mat- og vatnarskipanir

"Kóka tað, elda tað, skala tað ella gloym tað" er minnilig og bert partvís effektiv — rannsóknir av at fylgja reglunum vísa at ferðafólk sum fylgja reglunum nákvæmlega framvegis verða sjúk, í stórum partum tí at útseting fer fram í køkum teirra ikki kunnu síggja.

Tiltøkini við besta avkast: fløtt ella viðgjørt vatn, eisini til tenn, at forða ís av ókendum uppruna, heitt mat serstakliga heitt heldur enn at halda tað heitt, og frukt tú skal skala sjálvur. Hendurhygiena áðrenn at eta ger meira enn flestu matforðingar.

Tá tað ikki bara er ferðafólksdiaré

  • Blóð í avføringu ella høg feber. Leita læknishjálp heldur enn at sjálvbeina.
  • Symptomir sum vara meira enn eina viku. Tenk um parasittisk orsøkir, sum krevja aðra viðgerð.
  • Alvarlig uttan vatn, serliga hjá børnum og eldri ferðafólki.
  • Symptomir byrja eftir at tú ert komin heim. Sig læknanum hvar tú hevur verið; tað broytir differentialin.
  • Vedholdandi symptomir eftir ein akutt tilburð. Post-infektiøs IBS er ein viðurkennd og undir-diagnostiserad útgang.

Tað seinasta punktið hevur rætt til at fáa uppmerksemi: ein týdningarmikil minni partur menna varandi avføringssymptomir eftir ein infektiøs tilburð. Um tínar tarmar ongantíð fóru aftur til normal eftir ein túr, er tað ein viðurkennd fenomen og ikki nakað tú hevur funnið upp — sí okkara tarm-hjarnar evidens heimasíðu.

Vanlig spurningar

Eigur eg at taka probiotika, áðrenn eg ferðist?
Metaanalysur finna hóvligar minkingar [1][2]. Lág váði, lágur kostnaður, lágar ætlanir.
Eigur eg at taka antibiotika fyribyrgjandi?
Vanliga ikki. Mótstøða og aukaávirkanir vega tyngri enn ávinningurin fyri vanliga ferðing.
Er loperamid trygt at brúka?
Til einkennastýring í ikki-álvarsligari sjúku, ja. Forðast tað við hita ella blóði í hægdum.
Hvussu leingi eigur tað at vara?
Mest føri javnast innan fáar dagar. Longri enn eina viku, fá teg mettan.
