Whether diarrhea can heal on its own is related to the cause of diarrhea, which is also diarrhea. There are many causes of diarrhea in daily life, and if it is a functional diarrhea or if it is caused by cold stimulation such as cold, it can heal on its own. If the stool is more than 3 times a day and is not formed, watery or paste-like diarrhea, it is called diarrhea. Diarrhea caused by cold or eating a stimulating diet, such as chili peppers, excessive oil and other stimulating factors, can heal on its own after symptomatic dietary treatment and rest, or diarrhea caused by dietary allergies due to lactose intolerance, etc. Patients are still advised that they should be strictly controlled by diet, etc., and can also be relieved on their own. Diarrhea caused by severe bacterial or viral infections, inflammatory bowel disease or because of colon polyps or tumors, etc., must be treated with medication and allopathic treatment to get relief. Therefore, in cases of repeated diarrhea or even blood in the stool or fever, it is still recommended that patients should go to the hospital to identify the cause and have it treated by a doctor.
