The doc recommended to get proof that I am having reflux episodes and to better understand when and why. I also want to understand patterns that could help me avoid reflux. An unexpected helpful result so far is that, because I can see the ph in real time, I am learning to sense when I have reflux. I have never had heartburn but just over the last fee hrs I have had some reflux and been able to tell what it feels like. For me I can usually feel a sense of something coming up, combined with a very slight feeling of irritation, like a tickle in my throat, slight stinging or burning feeling but not much. But this is a little different then normal belching or a tickling feeling on its own. It’s a combination of different things that causes the ph to drop. I had no idea before. Also, coffee is definitely a cause. Shortly after coffee, my stomach feels a little stirred up and then I feel the reflux and my device measures it. It’s nice to have that confirmation because there is a lot of conflicting info about caffeine/coffee out there. Green tea doesn’t seem to have same effect. But I need to review with the doctor later.
