In cases where children experience vomiting and diarrhea, it is generally considered that the child may have acute gastroenteritis. For particularly severe diarrhea, where the stool is watery, it is advisable to give the child montmorillonite powder to protect the intestinal mucosa, along with probiotics, and oral rehydration salts to prevent dehydration. Because severe vomiting can also be a concern, treatments to stop vomiting can be implemented, such as administering Vitamin B6 via injection, or by administering oral aluminum phosphate gel. With the above treatments, vomiting and diarrhea can generally be well controlled. If the child has already developed moderate or more severe dehydration due to the vomiting and diarrhea, accompanied by varying degrees of electrolyte disorder, hospitalization for intravenous fluid therapy is then necessary. (Please use medication under the guidance of a professional physician, and do not self-medicate.)
