The painful condition where the contents of the stomach want to flow back the way they came to cause heartburn is something we may all have experienced in our lives: it is called acid reflux. This is a disorder of the gastrointestinal tract (digestive system) and even though this condition is often known by different names, they have similar symptoms. The digestive system uses hydrochloric acid to digest and process food. The disorder gives you a burning sensation in your chest near the heart and stomach, when the acid wants to return up the digestive tract.
