Achalasia synonyms

Achalasia is primarily known as esophageal achalasia or primary esophageal motility disorder, referring to the failure of the lower esophageal sphincter to relax. While historical terms like "cardiospasm" appear in older literature, modern medical professionals exclusively use the term Achalasia to describe this specific condition of the digestive system.

What are the historical and alternative names for Achalasia?

In medical literature, you may encounter various terms for Achalasia that reflect evolving understandings of its pathophysiology. Historically, the condition was frequently referred to as "cardiospasm," a term that is now considered inaccurate because the primary issue is a failure of relaxation rather than a simple spasm. Other older or less common synonyms include esophageal aperistalsis, megaesophagus, and idiopathic esophageal dilatation. These terms are rarely used in modern clinical practice but may still appear in older medical records or legacy research papers.

How is Achalasia classified in medical systems?

Official medical classification systems provide standardized nomenclature to ensure consistency across global healthcare providers. The following identifiers are used for Achalasia:

• ICD-10: K22.0 (Achalasia of cardia)


• Orphanet: ORPHA:98357


• OMIM: 200400 (Achalasia, familial)

Why does this condition have multiple names?

The naming of Achalasia has shifted as our clinical understanding of the digestive system has improved. Early researchers focused on the visible anatomical changes, such as the widening of the esophagus (megaesophagus), while others focused on the perceived "spasm" at the junction. Today, the term Achalasia—derived from the Greek word for "failure to relax"—is preferred because it precisely identifies the physiological deficit: the inability of the lower esophageal sphincter to open properly during swallowing.

Is Achalasia the same as other motility disorders?

It is important to distinguish Achalasia from other esophageal motility disorders, such as diffuse esophageal spasm or jackhammer esophagus. While these conditions share symptoms like difficulty swallowing and chest pain, they are distinct entities. With 319 people currently sharing their experiences on DiseaseMaps.org, our community emphasizes that accurate diagnosis through manometry is essential to differentiate Achalasia from other, less specific motility issues.
