You stomach makes acid normally as it should. This acid is supposed to stay in the stomach where is doesn't cause any problems. But if the acid moves upward into your swallowing tube (esophagus) then the acid will cause a burning sensation because the esophagus does not have the protective mechanism that exist in the stomach. So any acid that goes up into the esophagus is called acid reflux and many times this process results in heartburn.
The stomach secretes hydrochloric acid to help you digest proteins in your food. There is a ring of muscle where the esophagus meets the top of the stomach; if this muscle is weak, stomach juices (including acid) can leak upwards (reflux) through the ring. The walls of the esophagus are not able to tolerate the acid, so the cells try to become more stomach-like to protect themselves. This attempt to change cell types makes these cells at risk for becoming cancerous - acid reflux which remains untreated for 15-20 years can result in esophageal cancer.
