Hello, I Recently Had A Number Of Tests Done Due

Hello, I recently had a number of tests done due to having episodes of gastritis. EKG, Ultrasound of Gallbladder, Colonoscopy, Endoscopy, Chest X-Ray, and finally a Nuclear Test of Liver, and Gallbladder. All tests came back normal until The Nuclear Test came back showing that my Gallbladder was not squishing properly (not functioning correctly). I meet with a Surgeon that my primary care Physician has referred me to on Wednesday. My question to you is: Do you think removal of my Gallbladder is probable? If so, will I be able to eat most everything I use to before I started having these bouts of Gastritis 6 months ago?
