Question: HIDA Scan - Gall Bladder Ejection Fraction of 22%

 elessidril - Sat Mar 28, 2009 9:10 am

I am currently suffering from a mild to moderate pain in my upper right abdomen below my rib cage. Recently I had a HIDA scan that revealed that my Gall Bladder wasn't functioning properly, and the doctor told me that the removal of the Gall Bladder might alleviate my pain. Not being crazy about surgery, I was wondering if the ejection fraction of your Gall Bladder is 22%, can it improve with weight loss and proper diet, or will only get worst. Could serotonin levels affect the functioning of the Gall Bladder?

User avatar Hi elessidril,
A gallbladder ejection fraction below approximately 40% is considered abnormal. Weight loss and or changes in dietary habits such as decreasing fatty foods seem to alleviate some of the symptoms. You could certainly inquire with your physician regarding a repeat HIDA Scan six or eight weeks after lifestyle changes are made to see if there is any difference. Further recommendations by your physician could of course be made at that time. Serotonin is found in the gastrointestinal mucosa and does play an improtant role in intestinal motility. I hope you have found this somewhat helpful.
