Moderate sludge/tiny soft calculi in GB.

Hi, I got diagnosed with sludge/tiny soft calculi in gall bladder. USG says: The liver is enlarged (16.1cm). It appears bright in echotexture. No focal lesion seen. Intrahepatic biliary radicles are not dilated. Gall bladder: - It is distended. Moderate amount of sludge/ tiny soft calculi are seen in the Gall bladder lumen. The wall thickness is normal. Common bile duct is not dilated. I am non-alcoholic and not have any pain in chest or nausea. Its still in early stage, it got caught due to USG for my gerd. I have chronic GERD which caused LPR. although due to diet control my GERD is under control. I don't want to opt for surgery and want to know what are the chances that this will get cured with diet control and UDCA medicine. Thanks
