Thanks for writing your query.
After reading your post, I would like to advise that she should be clinically examined and investigated.
Following investigations may be helpful :-
1. Stool examination.
2. Liver Function Test ( LFT ).
3. Serum amylase and lipase.
I would advise that she should take an antacid
40mg once a day before meals along with Domperidone
along with digestive enzyme
preparation containing pepsin and fungal diastase after meals will have added benefits.
Further medical management can be planned after knowing the reports of the above mentioned Investigations.
I hope this is helpful to you.
