When someone can have a so-called “disease,” yet within an hour of eating differently than they have before, and the pain goes away almost instantly, and within days the sores have healed never to come back again, it’s not a disease.

If I punched you in the face and gave you two black eyes, you wouldn’t have “black eye disease.”  Because your new shiners are the result of getting punched, not a disease.

Acid reflux is like that.

It’s the direct result of foods and food combinations that cause the stomach to overproduce acid enzymes, which, for a variety of reasons flows up into your esophagus, creating a burning sensation, hence stomach pain.
