Dehydration
When someone is affected by diarrhoea, dehydration is a risk (especially for the old and very young).
Often diarrhoea is associated with vomiting so it may be difficult to replace lost fluids.
Note that due to the additional risk of dehydration in the very young, parents should be advised to call 111 if:4 their baby is under 12 months, particularly if they aren’t feeding properly; their child is under 5 and has any signs of dehydration; or their child is over 5 and still has signs of dehydration after using oral rehydration sachets.
