Q. What Causes Aspiration Pneumonia?

My father is hospitalized with aspiration pneumonia. What causes this?
A1Aspiration pneumonia is a pneumonia that develops due to the entrance of foreign material that enter the bronchial tree (air tubes), usually oral or gastric contents (including food, saliva, or nasal secretions). Aspiration pneumonia represents a either a bacterial infection or a chemical inflammatory process due to inadequate swallowing mechanism.
A2Aspiration 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.
