Thanks for your query.You have been detected to have a distended gall bladder
containing a stone of 6 mm size .Since you do not have obstructive jaundice
and pain it is labelled as a silent gall stone .You may neglect it but you have to get your ultrasound
scanning done repeatedly to watch the status of the size of the stone, Please note that there is no medicine that can dissolve the stone.Since gall stones
are formed because of gall bladder itself been infected best permanent remedy is to get it removed by Laproscopic procedure which is very safe and result oriented surgery..
