Ten Facts About Swallowing Disorders

4. Causes of Swallowing Disorders

Poorly fitting dentures, loose or missing teeth, dry mouth, acid reflux, and certain medications can make swallowing difficult, as may throat infections, surgery of the mouth or neck, or injuries to those areas. People who have had a stroke, brain injury, or Alzheimer's disease often develop dysphagia due to brain damage. Illnesses that affect the nervous system and muscle strength, such as Parkinson's disease, muscular dystrophy, Lou Gehrig's disease, multiple sclerosis, and cerebral palsy can make swallowing difficult, too. Some muscle abnormalities and autoimmune disorders can also cause dysphagia
