You are not digesting fat, your gallbladder was trapping it & forming gallstones. When you had it removed, nothing changed, you still were not digesting fat, but now you took away the stopper & it goes straight to your bowels. So the only thing to do is change what you eat & to supplement until you get it under control. So change what you eat to be low in fat & take 2 multi-enzymes on an empty stomach or 2 tabs with problematic meals. Any college biology book will tell you that to be able to digest food you have to have enzymes. Health food stores sell higher quality ones for $20 or Wal-mart has them for $7.95 Rexall brand. By taking them on an empty stomach it acts as a depurative or a blood purifier. Taking them with meals will help with the diarrhea. E-mail me & I can tell you more.
