For children with diarrhea, it is first necessary to determine the cause of the diarrhea. If the child has diarrhea due to a viral infection, with watery stools, the first step is to replenish oral rehydration salts to prevent dehydration and oral mucosal protectants, and then give the child probiotics. For severe diarrhea, some anti-diarrheal medications can also be taken. If the child has diarrhea due to a bacterial infection, or dysentery, which is also a bacterial infection, or caused by Shigella bacteria, it is necessary to treat the child with antibiotics under the guidance of a hospital doctor in order to achieve the treatment goal. (Please use medication under the guidance of a professional physician, and do not self-medicate.)
