gain or lose weight after removal?

have any of you gained or lost weight after they removed the gallbladder? i’ve heard many that they have gained weight sometimes even a lot more than what they were before &’ i searched it up &’ apparently it’s true you gain more weight BUT i’ve also heard people say that they’ve lost a lot of weight too &’ i’m pretty sure it’s because most of us now get the runs after eating something but im curious to which ones actually true &’ what’s y’all’s situation been like after the surgery
