The diarrhea of a 3-year-old child is like water. The parents should take the child to the hospital as soon as possible for blood routine examination, stool routine examination and other related examinations, and give antidiarrheal and fluid supplement treatment in time to prevent electrolyte disorders. Like water, diarrhea may be caused by intestinal infection, mostly bacterial dysentery and rotavirus infection. You need to go to the hospital to check and confirm the cause. If diarrhea is caused by bacterial infection, you can give cephalosporin antibiotics, such as cefaclor, cefixime, to control inflammation. At the same time, oral rehydration salt should be taken to replenish the fluid in the body, and yeast boulardii and montmorillonite powder should be taken to stop diarrhea. More serious need intravenous infusion treatment. For those caused by virus infection, it has certain self limitation, and only needs symptomatic antidiarrheal and fluid replacement treatment.
