Q. What Causes Aspiration Pneumonia? My father is hospitalized with aspiration pneumonia. What causes this?

A. Aspiration pneumonia is often caused by an incompetent swallowing mechanism, such as occurs in some forms of neurological disease (a common cause being strokes) or while a person is intoxicated. Another cause is during general anaesthesia for an operation and patients are therefore instructed to not eat or drink for at least four hours before surgery.
