Thank you for posting
From your description you did not mention for how long she has been having the diarrhea
and for how long she has been taking each individual medications. Diarrhea has a good number of causes which are usually microorganism intoxication of the GI tract and hence diarrhea. A stool exams will be needed for your mother to determine if there are no particular germs to be accused. In the other hand, medications can also cause diarrhea as side effect ( short term and long term). Among your mother's medications the first to cause diarrhea is lasilactone (combination of furesemide and spironolactone
, diarrhea is less common seen in lanoxin ( digoxin
) , ursodiol
while gemcal and rejunex are just mineral and vitamin supplements respectively which would not result to any diarrhea side effects except perhaps over dosage of gemcal which can cause stomach upset
I will advice you pay a visit to your mother's cardiologist and discuss this issue with him/her so he can either step off some other medications for a while before readministration until the crisis can be uplifted.
Meanwhile your mother would have to be orally re-hydrated in order to avoid dehydration
even though she is suffering from fluid retention now ( ascitis).
Hope this helps
