After reading the other posts regarding sphincter of oddi dysfunction after gallbladder removal and suffering from the same severe attacks that you and others have described ( I thought I was having a heart attack the first time!), I am convinced that we need more doctors to look into this problem! I can barely eat anymore, and since having my gallbladder removed 10 years ago, I have continued losing weight and am suffering from malnutrition, besides the horrible attacks that leave me helpless all day - and with 3 children to care for. I regret having my gallbladder out, even if it was non-functioning!!
