What symptom is associated with increased pressure in the lower esophageal sphincter?

Increased pressure in the lower esophageal sphincter (LES) is primarily associated with symptoms related to the digestive process, particularly the movement of food and acid. Dysphagia, which refers to difficulty swallowing, can occur when there is excessive tension or pressure in the LES. This increased pressure may impede the normal flow of food from the esophagus into the stomach, making swallowing uncomfortable or painful.

Additionally, a higher pressure in the LES can lead to functional issues, potentially resulting in food being unable to pass through smoothly, thereby causing a sensation of obstruction. Understanding this relationship emphasizes how alterations in the pressure of the LES can significantly affect swallowing mechanics, highlighting dysphagia as a key symptom of increased lower esophageal sphincter pressure.
