In 2005, I had a hypermotile gallbladder with similar symptoms. I was so frustrated with my gastroenterologist--he kept insisting that it wasn't my GB b/c labs, ultrasound, etc...were "within normal limits"
But I kept getting sick--either suddenly or peri-exercise. My fiance finally took me to the ER. Labs were normal, ABD CT unremarkable. We're both in medicine, we were so frustrated!
A general surgeon agreed with us. She stated the obvious: something wasn't right, a healthy 27y/o shouldn't be getting that sick that often, it was worth a "look around" in the OR.
MOST importantly---she refused to ignore the only "positive, aka abnormal" results: my HIDA scan with a large GB, a >60% EF & pain replicated by the CCK injection.
A HIDA scan isn't fancy. It remains one of the best "imitators" of human physiology studies we have. It doesn't even require very much experience to determine "normal" vs "abnormal" function. And CCK (the stuff they inject into your IV during the scan) is the naturally occurring endogenous hormone our GB releases to food stimuli. If you notice the same "pain" or diarrhea when the CCK is pushed into your IV, then that is significant.
In addition, "normal" & disease are on the same continuum. We all recognize that too little of something can be bad. Why isn't the opposite recognized as potentially just as bad? Only a few recognize hypermotility as a potential problem...primarily because "cancer" or "cirrhosis" isn't usually associated.
I had my GB removed in Oct of 2005. Since then I have NOT had the same pain or symptoms AT ALL. In the OR, my GB was quite large...and stuck to my intestines/liver with adhesions. SOMETHING had ticked it off at some point.
I don't know what it was--I suspect it was a latent, recently reactivated, double-stranded DNA viral infection of the vagus nerve branches that innervate the GB--but that's another novel, for another time.
If your Hida scan is abnormal, if the CCK replicates your pain, if all other GI workup has been negative & you are an otherwise healthy person, discuss GB removal with several surgeons & clinicians. If it is done laparoscopically, you can potentially go home that same day with a total of 3 Band-Aids on your stomach.
At the very least, consider asking them to put you on a 2-6wk trial of cholestyramine or another bile acid sequestrant.
