This study is a double-blind, prospective, single-center controlled trial conducted at a tertiary hospital, aiming to determine whether dietary therapy can effectively expel gallstones.

Gallstones are a common clinical condition, and their prevalence has been increasing globally in recent years. Gallstone formation is a result of various combined factors, and in its early stages, gallstones often exist in a sludge-like form. Currently, there is no definitive research on whether gallbladder sludge can be effectively expelled through medication or dietary therapy. Therefore, the investigators are conducting a double-blind, prospective, single-center controlled trial to verify whether gallbladder sludge-like stones can be effectively expelled using dietary therapy.

• Gallbladder sludge-like stones with a maximum stone diameter of less than 2 mm
