Hi. Thanks for your query. Noted the history and understood the concerns. GERD is usually not associated with any allergic phenomenon as you are suspecting. The cause of the GERD lies in the lax lower esophageal sphincter and/or hiatus hernia. Hence I would advise you the following in such a situation: Consult a Gastroenterologist for proper clinical evaluation, examination and investigations of an upper GI Endoscopy, barium studies and any other investigations as deemed necessary. This will get a proper diagnosis which is very important for proper management. Till then get started on a PPI like Omeprazole, antacid when on empty stomach. Soft bland diet. Most important is to avoid stress and anxiety at any cost. Further management as per the findings.
