The one universal sign of acid reflux that even a five-year-old
recognizes is the burning sensation felt in the throat and chest
after consuming oily or spicy food. A mere cheeseburger can
cause this extreme, but universal sign of acid reflux.

That burning sensation so commonly experienced by diners is
only one of the calling cards of acid reflux. Other symptoms
sufferers may experience include such things as a consistent
sore throat, bad breath or a bitter taste in the mouth. In spite
of good mouth hygiene, they may exhibit yellow teeth. They may
have acid regurgitation or a dry cough. Such symptoms are
perhaps just as serious and uncomfortable as the persistent
burning sensation that follows eating foods that trigger
heartburn or regurgitation.
