Acute gastroenteritis is particularly common in clinical practice, and its treatment in gastroenterology and emergency departments generally involves two steps. The first step is general treatment, where patients are advised to rest, eat easily digestible, liquid foods such as thin porridge and rice soup, and avoid spicy and irritating foods, such as chili peppers. The second step, if dietary treatment is not effective, involves the use of specific medications. For abdominal pain, pain relievers can be used, and for diarrhea, medications to stop diarrhea and regulate the intestinal flora can be used. Of course, the symptoms of acute gastroenteritis are varied, including abdominal pain, diarrhea, nausea, vomiting, and even fever. Therefore, if there is fever, it is generally recommended to take some antibiotics orally. If there is only diarrhea, it is only necessary to take medications to stop the bleeding and regulate the intestinal flora, and there is no need for anti-inflammatory drugs. Thus, the treatment plans vary depending on the different diseases and symptoms, but all medications should be used under the guidance of a doctor.
