What is the term for difficulty swallowing?

The term for difficulty swallowing is dysphagia. It describes trouble moving food, liquid, or saliva from the mouth through the throat and esophagus into the stomach. The problem can involve the muscles, nerves, or structures that coordinate swallowing.

Clinicians commonly distinguish oropharyngeal dysphagia, which affects starting a swallow in the mouth or throat, from esophageal dysphagia, in which food feels stuck farther down. Causes range from stroke and Parkinson’s disease to reflux-related narrowing, tumors, and muscle disorders. Persistent dysphagia can lead to dehydration, malnutrition, or aspiration pneumonia if food or liquid enters the lungs.

The word comes from Greek: dys means difficult or disordered, while phagein means to eat. A frequent mix-up is odynophagia, which means painful swallowing rather than difficulty swallowing. Aphagia is more extreme: it refers to an inability to swallow at all. Occasional trouble swallowing quickly is common, but recurring symptoms deserve medical evaluation.
