When does someone need to get their gallbladder removed?

It depends: on your symptoms and findings on imaging. If you are having right upper quadrant abdominal pain after meals that seems to get better when you avoid spicy/greasy foods and you have an ultrasound showing gallstones, then you would probably benefit greatly. Sometimes there are findings on imaging alone, even without symptoms, that would prompt surgery. Consult with a surgeon. Good luck!
