The clinical features of achalasia include:

  • gradually progressive, intermittent dysphagia to solids and liquids (1,2)
    • dysphagia associated with oesophageal carcinoma is more rapid and relentless than achalasia
    • insidious onset and progression prevents early presentation
  • regurgitation of fluids from the oesophageal sac may be followed by an aspiration pneumonia or frank vomiting (1,2)
    • patient may have a history of recurrent respiratory tract infections
  • heartburn is present in 27-42% of patients with achalasia (3)
    • may be initially misdiagnosed as gastroesophageal reflux disease (GERD) and treated with proton pump inhibitors (PPI)
  • chest discomfort or pain
    • may be due to oesophageal distension
