Talk to your Dr.: Causes of Gallstones include excess cholesterol, excess bilirubin (from liver cirrhosis, biliary tract infections) or gallbladder dysfunction. Risk factors include obesity, high fat/cholesterol/low fiber diet, diabetes, genetic predisposition, sedentary lifestyle, taking oral estrogen containing meds, or rapid weight loss. Talk to your Dr about what your specific findings are, and what you can do.
