Don’t wait talk to Your dietitian and your doctor, hang in there. I’m not sure about gal bladder, my mom had hers out and can’t eat food that is too greasy.
I haven’t done it yet but I am to supposed to go on an all liquid diet for 10 days before surgery. Minimum 60 grams protein 800 cal per day low to no sugar. To shrink liver and make room for surgery.
