Introduction
Diarrhoea is where you pass looser or more frequent stools than is normal for you.
Symptoms of diarrhoea
Diarrhoea can have a number of associated symptoms, depending on the cause and who is affected.
Causes of diarrhoea
Diarrhoea usually occurs when fluid cannot be absorbed from the contents of your bowel, or when extra fluid is secreted into your bowel, causing watery faeces.
Diagnosing diarrhoea
As diarrhoea usually improves within a week, you may not need to visit your GP. However, if you have persistent or severe diarrhoea, further investigation may be needed.
Treating diarrhoea
Diarrhoea usually clears up without treatment after a few days because your immune system will fight off the infection.
Preventing diarrhoea
To prevent the spread of infections that cause diarrhoea, you should always maintain high standards of hygiene.
'Hygiene wasn't always at the forefront of my mind'
TV producer Clare Gilbert arrived in Mumbai for a two-week backpacking trip and promptly came down with a nasty bout of diarrhoea.
