What is the connection with the gall blader and WLS. It seems like alot of people have it removed,

Liquid diets and eating small amounts of food right after surgery can cause bile in the gallbladder to become stagnant creating a good environment for sludge and stones to form. A high fat diet can also put you at an increased risk of developing gallstones, which is why a lot of people considering wls have already had their gallbladder taken out. I am taking ursidiol for 4 months to help prevent that from happening. Hope this helps a little.
