About this trial
Bile acid diarrhoea is a common cause of chronic watery diarrhoea. Treatment is life-long medication. However, about 50% of people have ongoing, bothersome diarrhoea. Findings from recent research on diet therapies and food intolerances have been used to develop a healthy dietary pattern called The 8x5 Diet. We will test the practicalities of conducting a randomised controlled trial of this dietary intervention.
