Divertikkelsykdom: Årsaker

Innhold i artikkelen

Det er sannsynligvis et samspill mellom flere faktorer som legger grunnlaget for divertikkelsykdom. Mekanismen er økt trykk i tarmen kombinert med svake partier i tarmveggen som gir etter for det høye trykket. Flere forhold kan gjøre deg mer utsatt for å utvikle denne sykdommen:

Annonse
  • Forstoppelse ser ut til å øke risikoen for å få divertikler
  • Det er noe økt hyppighet hos personer som har fått diagnosen irritabel tarm
  • Fiberfattig kosthold har i mange år vært oppfattet som en sterk risikofaktor, og personer som spiser 20-40g kostfiber om dagen har lavere forekomst av divertikkelsykdom enn de som spiser 7,5g om dagen. Forekomsten av divertikulose er lavere blant vegetarianere og i sivilisasjoner som har et mer fiberrikt kosthold
  • Økende forekomst med økende alder
