Achalasia Cardia occurs when nerves in the esophagus become damaged. As a result, the esophagus becomes paralyzed and dilated over time and eventually loses the ability to squeeze food down into the stomach. Food then collects in the esophagus, sometimes fermenting and washing back up into the mouth, which can taste bitter.
