What is dysphagia?

Dysphagia means swallowing difficulties, and usually caused by nerve or muscle problems. Dysphagia may occur after a stroke, throat and mouth cancer, gastro-oesophageal reflux disease (GORD), or as a symptoms of several different neurological disorders. Pain can be the sole cause of dysphagia; a pain in the throat makes swallowing difficult. However, dysphagia can be distinguished from similar symptoms including odynophagia, which is defined as painful swallowing, and globus, when the patient feels a lump in the throat. Although the medical term - dysphagia - is known as a symptoms or sign in most medical criteria, it can and is sometimes used as a condition in its own right.
