Dehydration is often the result of an illness, such as gastroenteritis, where fluid is lost through persistent bouts of diarrhoea and vomiting. Gastroenteritis is often caused by the Norovirus and Rotavirus.
Norovirus (winter vomiting bug), is the most common stomach bug in the UK and each year it is estimated that between 600,000 and 1 million people in the UK catch the winter vomiting virus. See our infographic to find out
more and for some tips on what you can do.
Those with an underlying medical condition, like diabetes, are also particularly vulnerable to dehydration.
