One of my concerns is about the long term use of 20 mg Omeprazole. I have Barretts esophagus but no dysplasia so far in biopsies. I have never had real heart burn but do have GERDS. I know the proton inhibitors interfere with absorption but although I am 86 & small frame, I do not have osteoporosis, because of intense exercise program, I believe. I take quite a few meds & Aleve for arthritis, which I am wondering if it is absorbed adequately. I am getting wordy, but thanks in advance. Vanna
