Gallbladder removed can u live without it and what is its function?

Life OK without GB. The gall bladder's job is to store bile, from the liver, & release it into the small intestine to digest fats. Without the gb, the liver still makes bile & directs it into the small intestine. People with gallstones have painful episodes of cholecystitis (inflammation of the gb) & do better without the gb. After gb removal 10-15% have irritation of the stomach/esophagus or diarrhea/colicky pain.
Semi. Bile is necessary but can still get there without gb in general. The volume and timing may be off, and some GI symptoms, may persist. In part depends on why it got diseased.
