Dysphagia has many possible causes and happens most frequently in older adults. Any condition that weakens or damages the muscles and nerves used for swallowing may cause dysphagia. For example, people with diseases of the nervous system, such as cerebral palsy or Parkinsonâs disease, often have problems swallowing.
Common causes of swallowing difficulty or dysphagia include esophagitis, esophageal cancer and epiglottitis, according to Healthline. Some of these health issues are considered medical emergencies, and urgent medical care should be sought once they are suspected.
