How to prevent gall bladder symptoms without surgery?

Maybe diet. I do not know if you have gallstones or not. Avoid fried, fatty, greasy foods (fried chicken, cheese pizza, hot dogs, ice cream, etc.) may help. But if there are gallstones causing pain, then sometimes medication such as actigall (ursodiol) may dissolve gallstones over time. Sometimes though any foods can cause stomach discomfort and nausea, then surgery may be indicated.
