I don't get it.
So some studies (i.e. http://www.post-gazette.com/stories/news/health/heartburn-meds-tied-to-cancer-308514/) show less symptoms means a higher risk for cancer, and some others seem to say symptoms duration, severity, etc. are linked to cancer in a positive correlation.
Then I read that bile reflux can cause worse problems and is difficult to diagnose and treat. So I would think a lot of people are walking around with bile reflux thinking it is acid reflux. So that should mean more symptoms = higher risk, not less.
Seriously, I have been struggling with GERD for 5 years + now and feel like I am farther from answers than ever before.
