Oral Problems
These are caused by failure of the facial muscles, tongue, or throat to function.
- Neuromuscular disease such as ALS or Parkinsons's
- Stroke that damages neurological function
- Myasthenia that slows muscle function
- Tumors that obstruct movement of the muscles
- Trauma to the head that impairs neurological functions
Pharyngeal Problems
- Neuromuscular
- Stroke
- Tumors
- Head trauma
- Laryngopharyngeal Reflux (LPR)
This is a common condition caused by acid from the stomach reaching up into the
larynx and causing burning on the vocal cords. It is a frequent cause of chronic
hoarseness, coughing, and frequent throat clearing.
Esophageal Problems
The commonest of these is GERD, gastroesophageal reflux disease. This occurs when
acid stomach contents flows back up into the esophagus. Many factors weaken the
valve that normally prevents acid from refluxing; hiatal hernia, stress, caffeine,
alcohol, tobacco, pregnancy, and many medications. If untreated this can lead to
esophagitis, an inflammatory condition of the esophagus with symptoms of heartburn,
nausea, and chest pain.
