Gallstones can cause extremely painful blockages within the gall bladder, and usually surgery is the main option used to remove them. As well as Ursodeoxy-Chloric Acid, there are other oral drugs which are sometimes used which may help to dissolve the gallstones such as Chenodiol.
Generally Gallstones are caused by too much cholesterol, bilirubin, or not enough bile salts. There can also be other causes such as the gallbladder not emptying as it should be for whatever reason. They could also come on if you are overweight, if you have excess levels of Estrogens in your body after pregnancy, and if you have diabetes. So, if you suspect you may have gallstones, seek medical advice and your doctor may prescribe you Ursodeoxy-Chloric Acid.
