Irritable Bowel Syndrome - Is a Stool Cow Protectant a Good Choice?

If someone's presenting with prominent diarrhea symptoms, would you be we're doing a workup for chronic diarrhea? Or are there still specific things similarly, where if they are having chronic loose stools, but none of these alarm symptoms. Would you pursue in pure treatment and seeing if that helps before going through the stool studies and presumably low yield workup? But something that I feel like we do for chronic diarrhea. And chronic diarrhea, especially in kids, is I think a very tricky thing.
