Diarrhea a dozen times a day is most commonly associated with acute enteritis. First, blood tests and ions should be performed to see the type of enteritis on the one hand and to determine if there is ionic disorder on the other. At the same time, symptomatic treatment should be carried out: 1. acid suppression therapy, the most commonly used are pantoprazole, lansoprazole, omeprazole, etc. 2. anti-inflammatory therapy, commonly used are levofloxacin, ornidazole, etc. 3. rehydration support therapy, such as conversion of sugar electrolytes, fatty milk, etc. 4. symptomatic anti-diarrheal therapy, commonly used are montelukast, etc. Wait for the results to come back to see if the program needs to be adjusted.
