"Why don't I have heartburn if my voice problem is from backflow of stomach acids?"
A Puzzle
For unclear reasons, patients with LPR do not commonly experience heartburn. Heartburn is a burning sensation in the chest that is not due to a heart problem but rather an irritation and/or inflammation of the esophagus (esophagitis) caused by backflow of stomach fluids into the esophagus, also known as gastroesophageal disease (GERD).
Since acid that affects the voice box must first pass through the esophagus, the fact that most reflux laryngitis patients do not get heartburn is a puzzle.
Different Reactions to Stomach Fluid
Physicians believe that the esophagus may be better able to resist the effects of stomach fluids (acid and enzymes) than the voice box.
- When exposed to the same stomach fluid, the voice box is more sensitive or susceptible than the food pipe.
- If only small amounts of stomach acid backflow into both the esophagus and voice box swelling and irritation may occur only in the voice box without affecting the "tougher" more resistant lining cover (mucosa) of the esophagus.
A Different Puzzle
Some patients with reflux laryngitis do experience heartburn (a burning sensation in the chest that is not due to a heart problem but due to irritation and/or inflammation of the esophagus or esophagitis).
Right Action Plan
Therefore, physicians need to perform a full evaluation to determine whether backflow of stomach fluids affects both the voice box and esophagus.
