What are the symptoms of Gastroesophageal Reflux Disease (GERD)?

The classical symptom of GERD is heart burn. It is a burning sensation located in the centre of the chest, either along with food intake or when fasting. Many patients also have repeated belching and sour eructation. Rarer presentations of GERD are due to the acid from stomach coming up and irritating other parts of the mouth and airways leading to recurrent dry cough, caries tooth, worsening of wheeze, recurrent sore throat etc. Symptoms are commonly worse at night and on lying down, but may happen throughout the day.
