- If you have recently experienced the following tummy symptoms after a recent overseas trip or after a bout of ‘food poisoning’, it is likely that you had an episode of acute gastroenteritis.
These symptoms are often short-term and can last between a few days to a week. However, research is showing that a small proportion of people can then go on to develop symptoms of irritable bowel syndrome (IBS). In a Nottingham survey1 of people reporting an episode of bacterial gastroenteritis (food poisoning) over a 6 month period,
· 25% had symptoms persisting up to 6 months.
· 1 in 14 then went on to develop IBS (or what is termed ‘post-infectious IBS’)
· Women or those with a longer duration of the gastroenteritis were at greater risk of developing post-infectious IBS
Unfortunately there is limited scientific evidence to guide our recommendations for dietary management for gastroenteritis. Below we have provided some practical suggestions which may be helpful for your recovery.
