What is Dysphagia?

Dysphagia is the delay or difficulty or misdirection of liquid or solid mucus from the mouth to the stomach which may coexist with eating disorders and may be the result of behavioral, sensory / aesthetic, motor disorders. This leads to malnutrition, dehydration, drowning and the presence of respiratory infections in the individual. Also the reduction of cognitive functions and the normal aging of the organism are factors that are responsible for the appearance of dysphagia. It is not a disease in itself, it is a symptom of another disease.

Diseases that cause Dysphagia:

  • Anatomical problems (osteophytes)
  • Neurological disorders
  • Vascular strokes
  • Head / neck cancers
  • Neurodegenerative diseases (Annoyance, Parkinson’s)
  • Traumatic brain injury
  • Respiratory problems
  • Burns in the swallowing mechanism
  • Respiratory problems
  • Cardiovascular diseases
  • Side effects of surgery (injury of the vocal cords, damage to a nerve.)


Nutrition is a broader concept that includes the perception of food (ie that it is something to be eaten) and preparation (ie the utensils we use).

It does not concern the part of physiology individually, that is, the way in which the structures work and cooperate with others and does not include swallowing but the first part of food processing.


It concerns the process of transferring food from the oral cavity to the stomach.
