How to dissolve gallstones
Consider oral dissolution therapy.
Your doctor may prescribe a course of ursodiol to dissolve your gallstones without surgery. These treatments are essentially bile acids in pill form.
Ursodiol, in particular, is a popular treatment because it is one of the safest common drugs available. Oral dissolution therapy is most likely to be successful in treating small stones (less than 1.5 centimeters in diameter) with high cholesterol content.
