Xerostomia--a review.

Xerostomia, or dry mouth, is a very common symptom amongst the terminally ill and can have profound negative effects on patients' quality of life. Yet, it is often considered trivial and therefore tends to be neglected and ignored. This review examines the pathophysiology, aetiology and methods of assessing xerostomia and its effects and discusses its management, with particular emphasis upon palliation. If xerostomia is managed sensitively and effectively, it is possible to improve patients' comfort and sense of well-being and so improve overall care.
