Is diarrhea also a sign of gall bladder disease?

No: Diarrhea is not a sign of gallbladder disease. Diarrhea can occur in some patients after having the gallbladder surgically removed, due to excessive bile release into the intestines. Sometimes this is temporary and resolves in time. If diarrhea is persistent, it can usually be treated by taking Cholestyramine once or twice daily. You should see your doctor to rule out other potential causes.
