NAUSEA AND VOMITING – REMOVING OR CORRECTING
Once the cause(s) for your nausea are found, it may be possible to remove or correct them. For example, if it is due to the cancer itself, some form of anti-cancer treatment would be a possible, but not necessarily the best, way to tackle it. If it is due to cancer in the brain, corticosteroids could relieve the nausea temporarily by reducing the pressure on the brain. If it is due to a bowel blockage, surgical removal or bypass of the blockage may be possible. If it is due to radiotherapy or chemotherapy it may be possible to change the doses, or even stop the responsible treatment. If it is due to, or aggravated by, anxiety, talking about and dealing with some of your worries, learning relaxation techniques and taking sedatives are three approaches you could consider.
The nausea itself must be treated if the cause is not to be emoved—either because this is impossible or because you decide that the likely cost of removing the cause would outweigh the likely benefit. I suggest you read pages 240-42 here. This section is basically about the treatment of nausea due to chemotherapy, but the same sorts of approaches can be followed for nausea due to other reasons. Remember, there are a number of different antinausea medications and it can be a matter of trial and error to find the one that suits you best. Chemical names of some good ones are prochlorperazine, metoclopramide, thiethylperazine maleate and chlorpromazine.
