The main treatment methods for acute gastroenteritis are as follows.

Firstly, the patient should rest in bed. If the patient has persistent vomiting, or shows signs of dehydration caused by vomiting, it is necessary to promptly rehydrate the patient. Regarding the diet, it is advisable for the patient to consume liquid or semi-liquid foods, such as porridge and rice soup, to prevent dehydration.

Secondly, it is crucial to treat the symptoms. If the patient has uncontrollable vomiting, we can administer antiemetic medications to alleviate this symptom.

Thirdly, in the case of antimicrobial treatment, common gastroenteritis may involve bacterial infections, which require antibiotics for targeted treatment of infectious diarrhea. However, it is important to avoid overuse or misuse of these antimicrobial drugs.

Furthermore, attention must be paid to dietary habits. It is essential to wash hands before meals and after using the toilet, and to properly disinfect raw vegetables, fruits, and meats, which should be thoroughly cooked before consumption, to effectively prevent the occurrence of gastroenteritis.
