✗ The myth everyone repeats
Heartburn is caused by excessive stomach acid that's too strong.
✓ What is actually true
Heartburn usually results from lower esophageal sphincter weakness, not excessive acid. Acid strength is consistent. Stomach lining protects against normal acid; problem is acid reaching esophagus.
