My mom had the same; had her gall bladder removed.
Ledzepfvr: Our doctor friend said that it is usually caused by eating junk food, and it building up in the gall bladder. My mom was hospitalized for a week, and when she came home, she was ordered to stay in bed as much as possible for about 3 weeks. It can be very serious if you're not taking care of your internal organs! If this bile clogs up too much, that's when it forms the gallstones, which are even more painful than when the bladder has to be removed entirely. Some great things to keep your liver and gallbladder healthy are some detoxes, like milk thistle. Something to stay away from are cholesterol-lowering drugs, because they actually increase the risk of gallstones!!
The best thing to do is have a diet rich in fiber and greens - lots of vegetables and fruits; also nuts which contain high levels of good fats!!
