My mother in law had her gallbladder removed and returned to work a week and a half later. Shortly after returning to work, she suffered memory loss. She would forget where she was, what day it was, her closet friends and family members. Her memory has gotten better. She also became depressed and constantly asks everyone what happened to her. She has diabetes( Type 2 I believe). We're trying to figure out what caused the memory loss the diabetes or the gallbladder removal.
