Achalasia can be difficult to diagnose because it has symptoms similar to other digestive disorders. Radiologists and esophageal disease specialists at Mayo Clinic have experience recognizing achalasia.
Tests useful in diagnosing achalasia include:
- High-resolution esophageal manometry. Using a catheter inserted down your esophagus, muscle contractions in your esophagus are measured when you swallow water. High-resolution manometry — which is available at Mayo Clinic — can assess the severity of your achalasia and guide treatment decisions.
- Esophagram (barium swallow). An X-ray visualizes movement of liquids through your esophagus when you swallow.
- Endoscopy. A flexible, narrow tube (endoscope) with a camera is used to view the inside of the esophagus and stomach.
