Hello. Give her carbo veg 30 - thrice daily. Nux vom 30 - at night.

Hello there.  I can understand your concern.  First of all, ask her to avoid such kind of foods which make her sick. And as of now, you can give her a tab. Pantakind once a day half an hour before food and get her checked out by a MD consultant physician in person for further evaluation and management.  Best regards. Dr. Anil kumar jain. Bangalore.
