CCK-HIDA scan 39% ejection fraction

[Ecl47]

Hello everyone,
For the past few years I have had what I believed to be gallbladder troubles and I was always able to manage it by watching what I ate, but recently it has gotten worse.  I’ve been having an increasing amount of attacks with ever present nausea and it is preventing me from being productive at work (I work as a CNA at a nursing home) I’m now finding that foods that used to be ok are now causing issues, so I made an appt. with my GI doctor and she sent me for an ultrasound and HIDA scan.  The ultrasound came back clear and the HIDA scan gave me an ejection fraction of 39% with some nausea and cramping experienced during the scan. I know less than 35% is typically the abnormal but I don’t know what else would be causing this. I haven’t heard back from my doctor on how we’re moving forward, but do you believe removal is likely? I’m a 20 year old nursing student so removal prior to me going back to school would be ideal if it has to happen. Thank you in advance
