if you've ever been on a low fat diet, starved for a very long time, lack of exercise, drank too much alcohol, smoked cigarettes, ate too much protein, ate too much refined starch/sugar, taken medication for a prolonged period, over stressed... these are some causes of gallstone formation. since we live in a very polluted environment, in a society with very bad eating habits. there's a good chance that you have gallstones. pain is a good indication aswell ;)
