When children experience diarrhea, it is defined by an increased frequency of bowel movements and changes in the stool's consistency, which might appear as watery, mushy, or mucus-filled. The mucus may contain blood streaks. Additionally, children may exhibit systemic symptoms including persistent fever accompanied by nausea and vomiting, while the frequency of bowel movements noticeably increases, and the fever may present as persistent high temperature. Due to frequent episodes of diarrhea, the child might show signs of dehydration such as poor skin elasticity, sunken eye sockets, and if not yet closed, a sunken fontanelle. The skin can be particularly dry, and the child may have reduced urine production. In cases of severe diarrhea, the child may also appear lethargic or drowsy and show signs of circulatory collapse.
