If I understand correctly, the sole purpose of the gallbladder is to store extra bile that is opportunely released in order to properly digest fat.
When the gallbladder is removed, what happens when there's not enough bile to digest a given amount of fat? And particularly, what happens with the fat that does not get digested?
I had my gallbladder removed a few weeks back and I've heard that consuming a relatively high amount of fat might produce problems such as diarrhea, gas and bloating, but I haven't experienced these (fortunately, or perhaps I haven't consumed a meal high enough in fat yet). In addition, I don't understand if the undigested fat is excreted or just stored in the body—as opposed to being properly used as a nutrient (I Googled this and there are mentions and accounts of both weight loss and gain; I didn't find proper research papers or a reliable source).
