hi. noted history of gallstones and frequent attacks of biliary colic. diet modification is a very important thing in dealing with gallstones. low fat diet is recommended. but, your condition might have been there for a long time already (chronic cholecystitis or inflammation of the gallbladder secondary to cholelithiasis or gallstone) and is now increasing in frequency of attacks. in this case, diet modification and medication could do the least for alleviation of your symptoms. definitive treatment is still surgical removal of your gallbladder or cholecystectomy. it could be done laparoscopically (goldstandard) or thru open technique. hope this helps. good day!! ~dr.kaye
