Although it is usually misdiagnosed and treated as gastroesophageal reflux disease (GERD), the main symptom is progressive dysphagia, accompanied by additional symptoms like nocturnal cough, heartburn, weight loss, regurgitation of undigested food and aspiration. The severity of achalasia and the effectiveness of treatments are commonly assessed using the Eckardt Symptom Score (ESS), which evaluates symptoms like weight loss, regurgitation, dysphagia, and retrosternal pain.

It typically involves a combination of diagnostic tools, such as time barium esophagram (TBE) study, which assesses the movement and clearance of barium in the
