In a definition essay, you explain the meaning of a certain term by giving a detailed description of it, and support your definition with clear examples or facts. Such explanations are needed if a term is special, abstract, disputed or does not have a common meaning.
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.
There are various causes of difficulty swallowing (dysphagia). See your doctor as soon as possible if you develop dysphagia. This is because a serious condition such as cancer of the gullet (oesophagus) can be the cause. As a general rule, the earlier a serious problem is diagnosed, the better the chance that treatment may improve the outlook (prognosis).
