The most common symptoms leading individuals diagnosed with achalasia to seek medical attention include:

Difficulty swallowing is one of the most significant complaints.
Food impaction in the esophagus,
Vomiting shortly after eating,
Chest pain and weight loss/failure to thrive resulting from difficulty eating.
Cough and frequent respiratory infections are other observable findings.
They frequently visit outpatient clinics complaining of a foreign body sensation in the esophagus.
If a foreign body unlikely to remain in the esophagus is found to be lodged there, then achalasia should be considered.
