Connie,
I had my gastric bypass done 10 years ago and 3 years ago I started having pain in my gallbladder. It's stones, but they weren't a problem then, pain would be just on and off. Lately, the pain has been constant so my primary care doctor sent me to a vascular surgeon. I have an ultrasound scheduled for Monday morning. Most likely, I'll have my gallbladder removed quite soon. Not looking forward to it, but I don't believe this will get any better with time, but worse.
In fact, I joined this forum today to read what others that have GBP surgery have gone through will gallbladder removal. (Hello everyone!)
You might want to call the doctor who performed your GBP surgery or otherwise your primary care physician. Get things checked out. Good luck!
