The other intervention that may help would be to try to replenish the good germs in the gut. With any cause of diarrhea, the good germs in the gut can get partly flushed out, and replenishing the good germs can help restore normal health of the gut.

You are correct to be drinking plenty of fluids and following a BRAT diet (bananas, rice, apples, and toast). As the stomach starts to calm down, then the diet can be advanced.

If you have any further questions, please let me know.
