The most common symptom of acute diarrhea is easy dehydration, so fluid replacement is very important to correct dehydration; even in acute diarrhea, the small intestine still has 60 digestive and absorptive capacity, so early feeding can reduce symptoms and improve nutritional status; fasting should not exceed 24 hours, and at the beginning of feeding, consider giving thin rice, potatoes or carbohydrate-rich foods, avoiding too greasy Avoid foods that are too fatty. The use of antidiarrheal medication can stop diarrhea, but it also reduces bowel movement and makes it difficult to excrete toxins, causing bacteria to grow. In addition, children who were breastfed as children have better intestinal resistance, so promoting breastfeeding is very helpful in preventing diarrhea in children.
