Hi thanks for contacting HCM.... Here your mother having gall stone.... USG done for gall stone for proper evaluation... If needed CT scan might needed... Because of obstruction if mucocele like condition there then surgical management needed.... If stone multiple and symptomatic with frequent pain then cholecystectomy needed.... Udiliv tablet taken that is made up of ursodeoxycholic acid .... It dissolve cholesterol in bile.... It affect cholesterol absorption in intestine ...so useful in gall stone... Meanwhile low fat diet taken.... Green leafy vegetables like spinach , bitter gourd , mustard green taken more.... If fever occurs and cholangitis there then antibiotic needed..... Take care... Avoid alcohol.... Consult gastroentetologist for proper examination and accordingly treatment Dr.Parth
