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