Mom, gallbladder, and flushes...

I'd like your advise on how to proceed with my mom's digestive system problems.

She decided to put off having her gallbladder removed and see what other options she has. She's having serious digestive problems, had a couple hernia/stomach operations with little benefit, and now can eat very few things without nausea. She also has daily diarrhea.

She asked me for gallbladder information. I'm thinking I should give her information on diet changes to help things along with information on the liver and gallbladder systems.

One big question is where she should start. With her current digestive problems, would she be okay doing a liver flush? Go on a strict diet for a week or so, then try a liver flush? Other options?
