Gerd Diet - Not Getting Enough Calories in Food Intolerance & Leaky Gut Posted March 28, 2015 · Report to Admin An ultrasound will just look for gall stones. A HIDA scan will check the gallbladder for functionality. Ask for a HIDA! Insist on it. My ultrasounds were always okay. My HIDA scan showed 0% functionality meaning it stopped working. I finally got the HIDA scan in the hospital because I was admitted for possible appendicitis. Something was rotting -- it was my gallbladder! When that fat came down the line, my gallbladder was not able to squeeze out the necessary bile to digest the fat. Now, I can consume lots of fat without my GB. I will tell you it is a family curse! Everyone said it was my gallbladder that caused me to pass out (there are seven kids in Dad's family and six have had their gallbladders removed -- no stones.....) But since I was a kid, I had to suffer over 25 years! Read up on gallbladders. I did not have any classic symtoms. Pain was never in the upper right quadrant. Pain was in lower abdominal area and lasted 12 hours. I passed out with each attack and would vomit upon awakening. Something to think about.... Indeed. My gallbladder was at 5% and ultrasounds and blood tests were normal. The HIDA scan was the only thing that found it. I had pain in the upper right though. No gallstones. Have you tried eating smaller meals throughout the day instead of larger ones?
