What is heartburn?
When acidic stomach juices flow backward into the esophagus a burning discomfort is felt in the mid-chest, behind the breastbone. This is the mechanism of causation of heartburn.
But why acid flows backward?
The esophagus is a tube-like structure that connects the pharynx to the stomach and acts as a passage way for food. This flow is normally uni-directional towards the stomach and the esophagus by virtue of its lower sphincter prevents backflow.
The lower esophageal sphincter acts like a valve that keeps acid in the stomach and out of the esophagus. If the normally contracted muscle relaxes the stomach acid flows backward into the esophagus.
So what are the causes of relaxation of the lower esophageal sphincter?
Some medications and food are responsible, these include: chocolate, caffeine, fatty or spicy food, onions, mint and alcohol. Acidic foods and vegetables are also considered.
Acid reflux relief could thus be prevented by avoiding such medications and food that relax the lower esophageal sphincter.

Acid production in the stomach
But acid is normally produced in the stomach without heartburn?
Yes; the stomach is full of acid; but is built to handle it and is protected by a specialized barrier of mucus and cell wall. The esophagus on the other hand is not well protected from the injurious effect of acid and results in a burning sensation when acid regurgitates into the esophagus.
