I had a HIDA SCAN in June 07 and the ejection fraction rate was 77%, I was have acid reflux symptoms so my doctor put me on Protnix for a few months. In October I woke up with pains in my stomach and very nasuea with dry heaves I went to the ER they did a Ultrasound and it was normal and said it was gastritis a few days later I had the same symptoms again I had and Endoscopy, Upper GI with small bowel follow through, Gastric Emptying Scan, CT SCAN with contract, bloodwork everything normal but I still had my symtpoms. I wake up in the middle of the night with nasuea and sometimes vomit stomach acid I have lost 11 pounds. The GI doctors sent me for another HIDA SCAN and this time the ejection rate was 40%, so he sent me to a surgeon and I am scheduled to have my gallbladder out. I am just afraid that I will still have the naseua after I have it out but that is the only thing they have found. I just hope this is the fix for my symtpoms.
