Meaning of dysphagia: Dysphagia is difficulty swallowing food, liquid, or saliva, ranging from mild discomfort to an inability to swallow safely.

Definition of dysphagia

Dysphagia is difficulty swallowing, which can involve trouble moving food, liquid, or saliva from the mouth to the stomach. It may arise from a problem in the mouth or throat that affects the initial swallow, known as oropharyngeal dysphagia, or from a problem farther down the esophagus that affects how material passes toward the stomach, known as esophageal dysphagia.

Possible causes include structural narrowing, muscle or nerve conditions that affect coordination of swallowing, inflammation, and growths that press on or involve the swallowing pathway. Dysphagia can range from mild discomfort with certain foods to significant difficulty that affects nutrition and hydration.

Because swallowing involves coordinated muscle and nerve activity across several structures, evaluating dysphagia often draws on history, physical examination, and specialized swallowing studies to identify where and why the process is disrupted.
