Chemotherapy Induced Nausea & Vomiting (CINV): A Chinese Medicine Perspective
What is Chemotherapy Induced Nausea & Vomiting
The cause of nausea and vomiting resulting from chemotherapy is not well understood, and the use of antiemetic drugs to treat CINV may lead to further unwanted side effects . Chemotherapy can cause nausea and vomiting by two major ways – peripheral or central mechanisms. In response to chemotherapy, enterochromaffin cells in the gastrointestinal tract release serotonin which starts the syndrome of chemotherapy-induced nausea and vomiting (CINV). Serotonin stimulates vagal afferent nerves which communicate with the brain. Through the dorsal vagal complex, the brain communicates back to stomach causing reverse peristalsis, which results in nausea and vomiting (NB: In Chinese medicine this is termed Rebellious Stomach Qi). Centrally, stimulation of the neurokinin 1 (NK1) receptors by substance P in the brain- stem can also lead to CINV.
Nausea and vomiting are the most common complications following chemotherapy treatment and usually lead to decreased quality of life. Acupuncture therapy is a safe and effective method for chemotherapy-induced nausea and vomiting (CINV) [1,2].
In China, Traditional Chinese Medicine (TCM) has been extensively used for thousands of years and applied in various diseases. Acupuncture’s ability to stimulate the body to release natural endogenous opioids (endorphins) and neurotransmitters or neurohormones, can reduce the nausea and vomiting resulting from chemotherapy treatment without the risk of further side effects .

How Does Traditional Chinese Medicine (TCM) view Chemotherapy Induced Nausea & Vomiting (CINV)
In Australia Chinese medicine practitioners are not permitted by law to treat cancer specifically. However, when treating a patient, a doctor of Chinese medicine must consider the patterns existing in the patient holistically. Therefore, while reducing nausea and vomiting is the primary focus, treatment for CINV will inevitably also affect the underlying factors of stagnant qi, blood and the accumulation of phlegm, as these are also part of the nausea and vomiting that results from chemotherapy drugs. During chemotherapy the attention is to strengthen the defensive energy (Zheng Qi) in the body .
