Good to hear you are recovering. It is worrying that the gallbladder trouble did not show up in blood tests or the first scans. Thanks for sharing the details.
Roughly six weeks after I began tirzepatide my gallbladder stopped working properly, though I had no idea what was happening at first. Almost four months passed before a HIDA scan showed it was only operating at four percent. It had probably been declining for years already, but dropping thirty pounds in roughly fifty days seems to have finished it off. Every day I felt awful and the pain was intense. No one could diagnose it and I started worrying about cancer or a tumor. I went through ultrasounds, CTs, and MRIs, yet nothing revealed stones or anything clear. Around two in the afternoon bile would back up and I would feel terrible. It got so bad I was not easy to deal with, even online, and a few folks said I was acting like a total jerk. After emergency-room trips, lots of lab work, and every scan possible, I finally received approval for the HIDA test. That gave the answer. My gallbladder ejection fraction sat at four percent. Nine days after the operation I am feeling decent. For quite a while I did not suspect my gallbladder because the pictures all looked fine with no stones or obvious harm, but poor function does not always appear on those tests.
