Pediatric diarrhea is a digestive syndrome characterized by an increased number of bowel movements and a change in the nature of stools, caused by multiple pathogens and factors. When a child has diarrhea, his gastrointestinal function is weak, and the absorption of nutrients is significantly reduced compared to normal. There is also significant intestinal dysfunction or clear intestinal infections causing the diarrhea. Grapes have a notable effect in promoting digestion; however, if a child with weak spleen and stomach functions consumes grapes, it could potentially worsen the situation by increasing the frequency of bowel movements. Therefore, it is advisable to minimize grape consumption in children with diarrhea.
