Hi and welcome to HCM.
is most commonly caused by gallbladder
stones and alcohol abuse
. Since you removed gallbladder possibility of pancraetits is less now,but possible. YOushould avoid alcohol, fats and abudant meals. After cholecystectomy
postcholecystectomy syndrome may occur which goes with your symotms,but also any kind of gastritis
can cause it as well. 1-2 months are needed till your digestion balance and you can expect improvment then. If your symotms persist you should do gastroscopy to evaluated all this. If you have paon that radiate to back it can be pancreatiti sagain, and visit hospital if you feel it that way.
Wish you good health.
