Sometimes it is caused by poor diet or eating raw and cold food, or it is caused by bacterial or viral infection. If it is accompanied by a fever, it is best to go to a regular hospital for a routine stool test to determine the causative organism before using medication. If it is only mild, observe and treat it first. If the diarrhea is more than 3 times, you can use Flavopiridol or Montelukast, doubling the first amount, which can effectively cover the digestive tract and prevent the irritation of the intestinal mucosa by the bacteria acid virus.
