My friend went to the ER today and she was told she passed a gall stone. She told me they did a scan with contrast and found she has 4 more stones. She was given 4 prescriptions: bentyl, coalase, zofran, omprazole. She wants to know what to avoid in vitamins, supplements, and foods. She is very particular to what she puts in her body, and is already doing a low-fat diet.
