Which condition involves the inability to eat due to loss of swallowing capability?

Aphagia refers specifically to the inability to swallow, which directly leads to challenges with eating. This condition can result from various factors, including neurological disorders, structural issues with the throat or esophagus, or cognitive impairments. When an individual experiences aphagia, they are unable to ingest food or liquids safely, significantly impacting their nutritional intake and overall health.

Anorexia, although it relates to a lack of appetite, does not necessarily involve the mechanical inability to swallow. Apnea refers to periods of temporary cessation of breathing and does not relate to the ability to eat. Antispasmodic refers to medications that relieve spasms, typically in the muscles of the gastrointestinal tract, but it is not a condition affecting the ability to swallow. Therefore, aphagia is the most fitting term for the inability to eat due to loss of swallowing capability.
