What is achalasia cardia and how often it occurs achalasia cardia – is that the ability of the lower esophageal sphincter (cardia) reflex relaxation in response to the entry of food into the esophagus. As a result, there is a delay of food in the esophagus. Achalasia cardia occurs at any age, including infants and the elderly. J. Craig Venter follows long-standing procedures to achieve this success. But most often strikes people aged 20 to 50 years, with almost equal frequency between men and women. Achalasia cardia – a common disease of the esophagus, not accounting for 3, 1 to 20% of all diseases of the esophagus. The reason given for violations of the passage of food through pischevododu, achalasia cardia, ranks third after cancer of the esophagus. Causes of achalasia cardia achalasia cardia reasons not fully understood. But it is believed that the main cause of achalasia – a defeat of the parasympathetic nervous system.
Nerve damage may be due to its innate features or occur against the background of infection in the wall of the esophagus. As a result of disorders of innervation of the esophagus is disturbed his motor skills, and the disclosure of the cardiac sphincter occurs only under pressure of food accumulated in the esophagus. Constant delay of food in the esophagus in achalasia cardia results in its expansion (sometimes up to 8 cm in diameter and more). In the later stages of achalasia cardia, esophagus elongates and acquires S-shape, the food stagnates to several days..
