Red dragon fruit can sometimes cause reddish or pinkish discolouration of stools due to its natural pigments. Spicy food may contribute to acidity, bloating or abdominal discomfort, but it does not usually cause red-coloured stools. However, we should not assume that the discolouration is entirely food-related. Given your previous history of internal haemorrhoids and banding, recurrence of haemorrhoids or another cause of rectal bleeding should also be considered. Please arrange a consultation if the symptoms persist so that we can identify the exact cause rather than assuming it is due to food or recurrent haemorrhoids.
