I went to a surgeon who specializes in repairing
hiatal hernias for another opinion. He told me that he believes my GERD is caused by
hiatal hernia and I should get surgery to fix it. He said the upper GI series isn’t always accurate because you’re lying down during it so the severity of hiatal hernias isn’t always detected. Is this true? Is it possible hiatal hernias can be seen on endoscopy, then not seen on upper GI series?
I’m very confused.
