Gallstones and Your Mood
When I was doing my medical training, there was a pretty simple rule about the gallbladder: if you find that there are gallstones, and someone is having symptoms (pain on the right side, up under the ribs, especially after eating fatty foods) then the gallbladder needs be taken out! If there are gallstones, but no symptoms, in most cases leave it alone (diabetes was an exception). It was, and is, a very mechanical view of the liver and gallbladder, sort of like swapping out parts on a car engine. If it is causing problems take it out, if it is not, leave it be. And it is true that a primary activity of the gallbladder is to function as a storage sack for the gall and wait until the right kinds of foods are eaten, then send a bunch of gall down into the small intestine. But the gallbladder is more important than that. For the active excretion of the bile through the gallbladder is an essential activity of the liver, and for digestion in general.
