Heartburn is a burning feeling in the throat or chest which may also be associated with a bitter taste. These symptoms are due to the return of stomach acid towards the mouth.
Heartburn and indigestion may be triggered by tight clothing around the waist, rich or spicy food, too much alcohol, stress, smoking and pregnancy.
Heartburn isn't always associated with food, so if you want to know more about your heartburn, please consult a healthcare professional.
