The symptoms of diarrhea caused by acute gastroenteritis can heal on their own, and not all acute gastroenteritis requires medication, so please rest assured. If the acute gastroenteritis is caused by a cold in the abdomen or by a careless diet, most clinical symptoms are not obvious and there may be mild abdominal pain accompanied by diarrhea. However, the number of diarrhea is often relatively small, perhaps 2-3 times a day or healing on its own after 2-3 times, and is usually not accompanied by symptoms of nausea and vomiting. Clinical symptoms vary from person to person, and some people may have a sensitive gastrointestinal tract and may experience significant upward and downward vomiting and diarrhea, and may even develop a fever, which requires medication. In patients with mild clinical symptoms, the disease can usually heal itself without medication.
