What is Achalasia Cardia?
Achlasia cardia is the failure of the (LES) lower esophageal sphincter to relax and let the food pass down to the stomach which leads to difficulty in swallowing food.
What are the symptoms?
Patients with Achalasia present with difficulty in swallowing, regurgitation and chest pain. It can be diagnosed by Upper Gastrointestinal Endoscopy, barium swallow or manometry.
The exact cause of achalasia is unknown. Possible risk factors may be infection, heredity or an autoimmune disorder which causes the body itself to damage the esophagus.
