a number of risk factors contribute to the formation of gallstones including genetics and gender (women are twice as likely as men to develop them). body weight is also a factor; the risk of gallstones is higher in people who are overweight and obese. diets that are high in fat and cholesterol and low in fiber appear to play a role. if you're overweight try to lose the extra weight; but do it gradually. there is a link between quick weight loss and gallstone formation. crash or "yo-yo" diets can cause the liver to release more cholesterol into the bile disrupting the normal balance of cholesterol and bile salts. that extra cholesterol can form into crystals leading to gallstones.
