Hello.
Thank you for asking at HCM.
I went through your daughter's history.
I guess, apart from white stool, she might be having nose symptoms or skin symptoms because
pollen allergy causing white stool is not likely.
However, as long as treatment is concerned, I agree with your doctor's treatment. In addition to that, I would suggest her plenty of oral fluids including
ORS (Oral Rehydration Salt) solution, which are commercially available.
Hope above answer will be helpful to you.
Wish your daughter a fast recovery and the best of the health.
Should you have any other query, please feel free to ask at HCM.
Thank you & Regards.
