contains bile which is helpful in digesting cholesterol
Once gall bladder is removed from the body, bile goes directly to the intestine, this may cause diarrhea
in around 10% of people.
Diarrhea may also occur if the patient take a lot of sweet foods, oily and greasy foods, on the whole they should restrict high fat containing food stuffs. So ask your mother to avoid such foods.
As of drugs your mother is taking Triglycomet and Glyza are antidiabetic
drug and Telmisartan
is antihypersensitive drug. Redotil is anti-diarrheal drug.
These drugs doesnt cause interaction and cause loose stools.
Hope I explained your query
