Re: DeMeester score and hiatal hernia?
Your doctor should have had a detailed conversation with you about this.
It is my understanding that the doctors consider "normal" as anything under 14.76 from a 24 hr pH test or under 16 from a Bravo averaged over both days.
Abnormal reflux is typically diagnosed using three criteria measured from the testing:
-DeMeester score greater than 14.76
-pH less than 4.0 more than 5.5% of the total time, more than 8.3% of the time upright or more than 3% of the time in the supine position
-pH less than 4.0 for more than 1.6% of the total time.
Based on my basic knowledge, it sounds like your score indicates some reflux, but is fairly borderline for a full GERD diagnosis. Your doctor is the one who makes that determination though.
Many people have some form of hiatal hernia. Most of the time, the doctors don't do anything about them and just monitor them. I can't help you much on interpreting the size of yours, but there is a lot of internet information out there.
Did your doctor talk to you about where you are going from here now that you have the results?
