GERD: Can be life threatening. May need more than OTC Meds. Make appointment with your GP or, preferably, a Gastroenterologist ASAP.

?NERD: About 1/3 of GERD patients do not respond symptomatically to proton pump inhibitors (PPIs). Many of these patients do not suffer from GERD, but may have underlying functional heartburn or atypical chest pain. Other causes of failure to PPIs include inadequate acid suppression, non-acid reflux, esophageal dysmotility and psychological comorbidities. Exclude cardiac and structural causes.

GERD: Consult a gastroenterologist for evaluation and treatment. Avoid alcohol,caffeine and nicotine. Get checked for H Pylori infection. In the meantime Carafate may be helpful. and you could try switching to zantac or pepcid, which are a different class of gerd medications.
