Hi I am 51 and female, have reflux, sleep apena, diabetic and high BP, Psoriatic arthritis. I have been having bouts of burping sulfar tasting gas. Passing gas does not reproduce smell. It seems to happen late in the evening and lasts until mid morning, also nausious. Mentioned to PCP, she said she thought it was reflux but it is now happening everyday and was wondering what it could be and what questions to ask her to have it looked into.
