Gallbladder questions

I was talking to a nurse friend about some problems I've been having and she suggested that I have a gallbladder problem--I was wondering what you thought. My symptoms are chronic diarrhea and chronic hunger. I've read that the diarrhea is a symptom of gallbladder problems, but never the hunger until today. I can eat a full meal and be satisfied when I'm done, but within an hour I'm feeling very hungry again. I've had three babies in the last 3 years and I was "blaming" it on them. I thought maybe my metabolism was really messed up. However, my friend said that it sounds like my gallbladder isn't breaking down the fat in my diet. She said that my struggle to lose weight would indicate that my body isn't processing fat correctly too. I'm looking for any help or suggestions before I go to the doctor in April for a checkup.
