My HIDA scan shows EF rate of 7%, debating about having gallbladder removed

[Rica08]

I have been having chest pains for over a year. Mid chest pain sometimes in neck & ears too. Never after eating or any heartburn. My PCP had me do all the heart tests. All neg. after an endoscopy, ultrasound & HIDA scan, I have Barrett’s esophagus, hiatal hernia, gallstones & an EF rate of 7%. My only symptom is the chest pain that lasts about 10 min. Sometimes 2-3 times a week or a week or two in between. I am 54 & overweight (220); i wonder if diet could help instead of surgery? A lot of scary comments on here about the surgery.
