Hormones then signal the
gallbladder to contract and it pushes the bile into a common
bile duct and it flows down to the intestines to help emulsify
the fats we eat so they can be digested and absorbed.
Anything that prevents the flow of this bile reaching the intestines:
stones moving from the gallbladder into the ducts; ducts that
have narrowed; ducts that are mal formed; growths in the
ducts; gallbladder inflammation; or bile duct infection
