Did you know?

  • Unlike the English 'stomach bug' which implies a tiny creature, the French gastro focuses entirely on the type of inflammation occurring in the gut.
  • In some Francophone regions, avoir la gastro is used colloquially to describe any sudden nausea, even if the cause is not a viral bug, such as food poisoning.
  • In many French-speaking households, instead of naming the 'bug', people will simply say they have mal au ventre, which is a much more general way of saying 'stomach ache'.
