Pseudodysphagia

Severe pseudodysphagia is the irrational fear of swallowing and minor pseudodysphagia is the fear of choking. The symptoms are psychosomatic. The act of swallowing becomes mentally linked with choking or with undercapacity of the esophageal opening. This can induce panic reactions before or during the act of swallowing. The sensation of difficult swallowing feels authentic to the affected individual, although it is based on nothing in reality. It is important that dysphagia (difficult or painful swallowing) be ruled out before a diagnosis of pseudodysphagia is made.

Fear of choking is associated with anxiety, depression, panic attacks, hypochondriasis, and weight loss. The condition can occur in children and adults; it is equally common among males and females. Quality of life can be severely affected. Avoidance of restaurants or social settings is common, since sometimes food can only be taken in small bites or with liquid.

Characterization of idiopathic dysphagia as psychosomatic has recently been challenged by published case reports documenting instances of "pseudodysphagia" patients suffering from the little-known entity omohyoid muscle syndrome. Should this syndrome be found to have a spectrum of severity (particularly if mild cases of OMS do not demonstrate the typical transient soft neck mass), the medical community may need to consider ruling out this subtle, truly somatic etiology before arriving at true pseudodysphagia, the latter being essentially a diagnosis of exclusion.
