Can Excess Of Bile Can Trigger Diarrhea?

Why do you get diarrhoea with gallbladder?

Yes, definitely, especially if your gallbladder has been removed.  The gallbladder stores bile and released it when needed.  Without the gallbladder, the liver pumps the bile straight into the intestines.  If you don't eat enough food to use up the bile, diarrhea will result.  This does not happen with everyone.  There is medication from the doctor that can control it, but a natural way to do so is to take Caltrate-D (calcium supplement).  It soaks up the extra bile.  If you take too much calcium, it will cause constipation so experiment with the amount until the diarrhea is controlled.  It can also be controlled by eating more food, especially foods that need a lot of bile to digest (such as beef).  Unfortunately eating more will result in weight gain.
