Defining diarrhoea
Defining diarrhoea
Customers with diarrhoea may describe having a tummy bug, food poisoning or traveller's diarrhoea. Lifestyle pressures, infection or medical conditions can all be triggers of diarrhoea,3 which can be a real inconvenience for your customers, interfering with their daily activities, or leading to dehydration.
Diarrhoea can be defined as acute, persistent or chronic. Customers with persistent/chronic diarrhoea should be referred to their GP.
