What Causes the Valve to Malfunction?
In some people, the lower esophageal sphincter relaxes at the wrong time or becomes weakened. This allows stomach contents to escape and travel up the esophagus. This causes burning, irritation, and pain. Surprisingly, not everyone who has acid reflux experiences a burning sensation. Other times, burning in the area of the chest and abdomen is caused by a condition other than reflux. Sometimes chest pain may occur due to a heart attack or other serious conditions. Acid reflux is the main symptom of gastroesophageal reflux disease (GERD), but GERD is associated with other symptoms like nausea, dry cough, hoarseness, sore throat, trouble swallowing, and a feeling of a lump in the throat. See your doctor if you experience pain, burning, or irritation in your chest or abdomen.
