Can severe esophogial erosion cause diarrhea?

NOT a diarrhea cause. An esophageal erosion is usually caused by gastro-esophageal reflux disease (gerd). The symptoms of gerd are: heartburn, chest pain, swallowing difficulty, and cough (@ night). Acid blockers (ppi's) such as Omeprazole (prilosec, zegerid) are prescibed to decrease acid but may have diarrhea as a side effect. You may want to try an alternate otc medication, prevacid (lansoprazole). Hope you are better soon!
