I am 65 years old. Sure sounds like you've been through a lot. I was taken off Omeprazole also (had been on it for several years)...trying to control my GERD with Famotidine but it certainly doesn't work as well. In trying to read and learn more about NET, there was a connection between proton-pump inhibitors causing an increase in the
chromogranin A blood test - mine was above the normal level at 156, but I've read where some levels can be in the thousands. It listed some other drugs that can affect the chromogranin level as well. I have a consult scheduled with my GI practice on June 7. My colonoscopy is due next year, but I want to go on and have it done; I'm worried I may have some colonic polyps. In the meantime, in the middle of all of this, my body decided to try to move a kidney stone that I've had for years with no problems....and when it did move, I was quite ill - transferred by ambulance from one hospital to another that could take care of it, and I became septic during this process. This happened in April, and I'm still somewhat recuperating from that whole episode.
