What is the definition of dysphagia?

Dysphagia specifically refers to difficulties in swallowing, which can be caused by various underlying medical conditions affecting the esophagus, throat, or muscles associated with swallowing. This condition can manifest as pain during swallowing, the sensation that food is stuck in the throat or chest, or even the inability to swallow at all. Understanding this definition is crucial, especially in the medical and imaging fields, as it aids in identifying patients who may need specific interventions or diagnostic evaluations related to their swallowing function. Identifying dysphagia is essential for ensuring proper nutrition and preventing complications such as aspiration pneumonia or malnutrition.
