I am suffering from gall bladder and last month I did mri wherein the gallbladder size has increase which is now 15 mm. Is happening because of doing night shifts. Also doctor has advised me to do surgery. Please suggest if I have to stop doing night shift because I feel that this thing has happened for not having food on time, no sleep on time no routine at all because of night shift. I have been doing night shifts from past 4 yrs.
