Slkanowitz: thank you for your response and recommendation to take omeprazole. After some research I read that the finding of the z-line on an EGD is a normal finding. Since mine said Z-line was regular (meant it was normal)? And since I’m around 5’10” in height a 39 cm is normal? If I read it right it’s people with “irregular” z-line’s that could have Barrett’s Esophagus? Thanks again for your response, this was helpful.
