Most foods do not have the ability to stop diarrhea, so it is usually mainly through medications. Antidiarrheal medications are available for non-infectious factors. Infectious factors do not use antidiarrheal drugs, may mask the condition, affecting the correct treatment. 1. Non-infectious factors: when choosing antidiarrheal drugs, the main choice is to pick montmorillonite powder and medicinal charcoal that have absorption and astringent effects. You can also choose loperamide, which can reduce intestinal peristalsis, as well as diphenoxylate. Or you can choose growth inhibitors and eliminators that inhibit intestinal hypersecretion. 2. Infectious factors: If the diarrhea is infectious, it is not recommended to use antidiarrheal drugs freely when the infection is not effectively controlled. There are many types of antidiarrheal drugs, but diarrhea has many causes, do not use drugs at random. Medications should be used under the direction of a doctor.
