How to diagnose Achalasia ?
How is achalasia diagnosed? Achalasia is suspected in individuals with dysphagia (difficulty swallowing) and in instances where regurgitation symptoms are not responsive to protein pump inhibitor medication.  The diagnosis of achalasia is confirmed by manometry (test that measures how well the esophagus is working); however, other tests such as upper endoscopy and upper GI X-ray can additionally be useful.
