Her over the counter Zantac or Tagamet probably stopped working and she was on a long waiting list to be scoped and get a more potent drug like an acid inhibitor like the proton pump inhibitor drugs.
Bleeding ulcers used to be a severe problem and sometimes fatal before Tagamet and Zantac were marketed and later on proton pump inhibitor drugs.
0b0z0 care will bring back those good old days in medical care.
