When symptoms of heartburn are not controlled with modifications in lifestyle, and over-the-counter medicines are needed more often than twice a week, or symptoms remain unresolved on the medication you are taking, you should see your doctor.

When GERD is not treated, serious complications can occur, such as severe chest pain that can mimic a heart attack, esophageal stricture (a narrowing or obstruction of the esophagus), bleeding, or a pre-malignant change in the lining of the esophagus called Barrett's esophagus. Symptoms suggesting that serious damage may have already occurred include:

• Dysphagia: difficulty swallowing or a feeling that food is trapped behind the breast bone.

• Bleeding: vomiting blood, or having tarry, black bowel movements.

• Choking: sensation of acid refluxed into the windpipe causing shortness of breath, coughing, or hoarseness of the voice.

• Weight Loss
