Moderate consumption of prunes will not lead to the occurrence of diarrhea, but it may lead to diarrhea if you have poor gastrointestinal function or eat unclean prunes. As a common fruit, prunes are rich in fiber and vitamin A, and contain some dietary fiber. At the same time, prunes also contain mineral elements such as potassium and iron, and do not contain cholesterol and fat, which is one of the fruits suitable for eating. Small amounts of prunes do not usually cause diarrhea. Only when consumed in excess or when the gastrointestinal function is weak, gastrointestinal discomfort may occur, which in turn causes diarrhea, and eating unclean prunes may also lead to diarrhea. If you have diarrhea after consuming prunes, you need to consult a doctor in a timely manner to identify the cause under the guidance of a medical professional and get standardized treatment from the doctor.
