Childhood diarrhea is caused by multiple pathogens, characterized by an increased frequency and change in the nature of bowel movements. The primary clinical manifestation in children is an increased number of bowel movements. In cases of mild diarrhea, the child may experience some vomiting, then a low fever, pale complexion, with no increase or decrease in weight. Generally, the condition resolves within 3 to 7 days. In cases of severe diarrhea, the frequency of bowel movements can reach more than ten times per day, with a high water content and occasionally mucus. Under these circumstances, the child's appetite is very poor, often accompanied by vomiting and high fever, rapid weight loss, significant emaciation, and visible symptoms of dehydration. In severe cases, complications such as acidosis, hypokalemia, hypocalcemia, and hypomagnesemia can occur.
