I had my gallbladder out April of last year... My diet has changed ALOT for the longest time I couldnt eat meat... Id get so sick. now the things Ive learned to avoid are: fatty foods, greasy items, things that are too rich, sugary etc. The things that post op you wont eat anyway Im hoping after I have my sleeve done on tuesday the dumping syndrome I have from the gallbladder removal will lessen! I admit though it does feel so much better not having it anymore!
