Patients with acute gastroenteritis usually have abdominal pain, diarrhea, nausea, vomiting, fever and other symptoms. For its remission, it is first necessary to know whether the patient has a clear infection. It is recommended that patients check blood routine, liver and kidney functions, and do stool routine and stool culture. If the patient's blood routine test indicates that the proportion of white blood cells or neutrophils in the patient is increased, or there is no white blood cells in the stool routine test, anti infection treatment will be given at this time. If the patient does not have a clear history of allergy, cephalosporins or quinolones are generally used. If the patient's diarrhea symptoms are very obvious, some antidiarrheal drugs are also needed. Montmorillonite powder is the most frequently selected clinically. At the same time, some drugs can be used to repair intestinal mucosa, such as glutamine. If the patient also has obvious symptoms of nausea and vomiting, it is also recommended to use some acid inhibiting and stomach protecting drugs, such as omeprazole, pantoprazole, etc.
