Dietary therapy aims to expel gallstones without surgery
NCT ID NCT06699030
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether a specific diet can help people pass very small gallstones (sludge) without surgery. One hundred adults with tiny stones (less than 2 mm) will be randomly assigned to a special diet or a control diet. The main goal is to see if the diet can completely clear the gallbladder sludge within three to six days, as confirmed by ultrasound.
