Description
Achalasia is a disease of the Esophagus.
When the Muscles of the Esophagus do not function properly, the food fails to move to the Stomach. It is called Achalasia.
When we swallow food, it directly goes to the Throat and then to the Esophagus. The opening that separates the Throat from the Esophagus, is the Sphincter. The lower Sphincter separates the Stomach from the Esophagus. The food moves to the Stomach and the Sphincter closes immediately to prevent the back flow of the Food. But if the Sphincter does not function properly, the food fails to move into the Stomach.
Normally, there is contraction and relaxation of the Muscles in the Esophagus. This action is known as Peristalsis. It pushes the food into the Stomach. But if the Parystalsic action does not take place, it gives rise to Achalasia.
