Sorry to hear you need a gall bladder operation. It may have to do with an imbalance of hormones which can be caused by a problem with metabolizing cholestrol properly (Cholestrol is the raw product which eventually turns into various hormones). Unfortunately, it may take researchers many more years to discover the actual malfunctioning mechanisms that cause gallstones. Check out Dr. Gabe Mirkin's web page and key word: gallstones. He states that there's a increased correlation between gall bladder removal and later colon cancer. Good luck. I'm in the same boat.
