Whether diarrhea can heal on its own is judged by the cause and severity of the disease.
If the diarrhea is only caused by improper diet or cold, it can usually heal on its own.
if the diarrhea is mildly caused by bacterial or viral infection, it may also heal on its own
If the diarrhea is caused by intestinal tumors, it cannot be cured by itself.
Therefore, it is important to judge whether diarrhea can heal on its own, taking into account the cause and condition, and not jumping to conclusions.
