Hello and welcome to HCM.
Thank you for your query.
Your symptoms do resemble a condition called gastroesophageal reflux disease
). But let me list a few possibilities for the same:
-Peptic ulcer disease
(which has been ruled out in your case)
(should have been noticed during the endoscopic examination)
-Irritable bowel syndrome
-Inflammatory bowel disease
Please discuss the possibilities and rule out/diagnose the above mentioned conditions. Also, please note that if GERD has been diagnosed, your treatment regimen should include: antacids, proton pump
inhibitors, H2 blockers, prokinetic agents (to strengthen the lower esophageal sphincter), etc.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.
