If you have chronic heartburn, you may actually be suffering from GERD or Gastroesophageal Reflux Disease. This condition develops when stomach acids ‘back up’ or refluxes into the esophagus.
Achalasia of oesophagus is a condition where the lower oesophageal sphincter (LES) is dysfunctional leading to altered motility of the oesophagus. The LES becomes very tight, not allowing solid food to pass down easily into the stomach.
