Concerned with the care and study of those who suffer from nausea and/or vomiting, this text provides an overview of the subject and gives practical treatment guidance. It describes illnesses and other conditions in which nausea and/or vomiting may occur, including those which may have significance for differential diagnosis. Since nausea and vomiting are such common side effect of medical treatments and drugs, information about dangers and complications arising from nausea and vomiting themselves is also provided. Among the arguments put forward in the book are: that nausea and vomiting are insufficiently understood; that treatments are unduly limited and that clinical trials are too often poorly designed; and that large numbers of practitioners are poorly informed. The book seeks to provide survey, overview and guidance adequate to the needs of primary care practitioners - physicians, nurse practitioners, health psychologists and ancillary professionals. It should also provide a provocative introduction to problems and to new research directions for advanced scholars and practitioners; and be a useful resource for academics in oncology, cognitive neuropsychology, obstetrics, olfactory biology, for those with a focus on women’s health and for holisitc medicine practitioners.
