I agree with Bruce. There is a difference between having GERD, which is extreme, and having GER, which is commonplace. Those of us with GERD have more serious defects in your LES valve Starry said, we also can have "silent GERD" and not even be aware of the harm it is doing.
When reflux occurs more often, is bothersome, and causes injury, it becomes labeled GERD.
If your LES works the way it is meant to work, you may get some reflux, but not enough to cause harm to your esophagus. Normal levels of reflux CAN cause problems in the lungs, throat, and larnyx, etc. with LPR, but that's another story.
When I had my PH monitor testing, I was always within what they call the "Normal Range". That's the range that anyone out on the street might have. I believe it's anything under 14.4. That is definitely some reflux.
That's the crux the LPR problem. LPR sufferers often suffer serious and uncomfortable effects from that "normal" reflux, and therefore kind of fall between the cracks. My asthma doctor often grumbled to me about GI docs who don't understand that a small amount of reflux can cause big problems in the lungs. He said that GI docs are only worried about large amounts of reflux that can harm the esophagus.
Say an LPR patient (like myself) has surgery to clear up symptoms (in my case very seriously ill lungs). The surgeon CAN'T get the reflux to zero without closing off the opening to the stomach. Therefore, that patient could still get reflux, and continue to have the same or similar symptoms after surgery. Thankfully, very often the symptoms improve in spite of this.
Although all my PH tests scores were low--the first one was 4 (later, 10 and something like 14.8)--I was having acid-affected lungs. That's the problem...if a surgeon can't get reflux to zero and is only going for "normal" amounts of reflux, LPR patients could have the surgery and continue to have the problems. (If he goes for zero reflux, the patient would not be able to swallow.)
That said, I had the surgery in February 2009 and my lungs did improve after two and a half months, (it takes time to heal long-term damage) and that improvement has continued. I'm certain I'm not reflux-free, but apparently my reflux is consistently better than it was prior to surgery because my lungs are healthy now (other than my normal allergy induced symptoms from time to time).
Someone like Jabronie is an ideal candidate with "off the charts" reflux. A surgeon can be certain to make her life better with surgery, because she's not starting in the "normal" range. They love a patient who has typical and especially severe GERD, since they can be confident that symptoms will be improved.
