Achalasia is not a contagious disease and cannot be spread through contact, saliva, or any other means. It is a chronic digestive disorder caused by the degeneration of nerve cells in the esophagus, and there is absolutely no risk of transmission to family members, caregivers, or friends. What is the actual cause of Achalasia? Achalasia is a primary esophageal motility disorder characterized by the loss of inhibitory ganglion cells in the myenteric plexus of the esophagus.

Achalasia is not a contagious disease and cannot be spread through contact, saliva, or any other means. It is a chronic digestive disorder caused by the degeneration of nerve cells in the esophagus, and there is absolutely no risk of transmission to family members, caregivers, or friends.
Achalasia is a primary esophageal motility disorder characterized by the loss of inhibitory ganglion cells in the myenteric plexus of the esophagus. This leads to the failure of the lower esophageal sphincter to relax during swallowing and a loss of peristalsis. While the exact trigger remains a subject of ongoing research, current medical consensus points toward a combination of factors, including autoimmune responses, viral triggers, and a potential genetic predisposition.
Because some theories suggest that a viral infection (such as herpes simplex or measles) might trigger the immune system to attack esophageal nerve cells in susceptible individuals, some people mistakenly believe Achalasia is infectious. However, the virus acts only as an initial environmental trigger in a predisposed person; it does not mean the person with Achalasia is "shedding" a virus or that the condition is transmissible to others.
While Achalasia is not caused by poor hygiene or lifestyle, researchers are investigating why certain environmental factors might influence its development. Factors currently under investigation include:
Living with Achalasia can be isolating, especially when others do not understand the condition. It is important to emphasize that Achalasia poses zero risk to those around you. With 319 members in the DiseaseMaps community currently managing Achalasia, you are not alone in navigating the social and physical challenges of this digestive disorder.
