If diarrhea occurs all the time and can be watery stools, the number of times is more frequent, the response measures are as follows: 1. The patient’s water-electrolyte balance needs to be ensured. If the patient’s fluid loss is large, especially for young children and elderly patients, dehydration is very likely to occur. At this time, in addition to the usual antidiarrheal treatment, it is necessary to ensure that the patient’s fluid balance is maintained. 2. It is necessary to understand the cause of the patient’s diarrhea, whether it is due to infectious diarrhea or chronic diarrhea. If it is infectious diarrhea, first of all, we need to know whether the cause of the patient’s infection is Salmonella infection or other causative factors, the common ones are generally Salmonella infection. At this point, the patient can be treated with anti-infective therapy based on the results of the tests, such as blood tests, calcitoninogen, C-reactive protein and other infection indicators. After the anti-infection treatment, combined with the usual antidiarrheal treatment, such as montelukast and other antidiarrheal treatment, as well as rehydration treatment, basically can ensure the patient’s water-electrolyte balance, and prevent the further progress of diarrhea.
