diarrhea due to excess bile

When researching diarrhea due to excess bile all information that I find is related to after having gall bladder removed. I still have my gall bladder and have had a HIDA scan which has shown that my gall bladder is hyperactive. After greasy meals I can feel my gall bladder contracting. I have instant cramping, extreme gurgling in my stomach and have immediate yellow watery diarrhea. My question is this due to my gall bladder because I can not find any information regarding a hyperactive gall bladder and symtoms (symptoms)?
