Q: I've read that acupuncture raises blood pressure in individuals with normal blood pressure. Does this always happen and if so, after treatment, does the blood pressure go back to normal?
A: We have looked carefully through all of the research databases and checked for anecdotal accounts on the web, but apart from people who have experienced a raised blood pressure as a nervous response to having treatment itself, there is no evidence to suggest that acupuncture would raise blood pressure in someone with a normal blood pressure. Clearly if someone has low blood pressure, treatment might have the effect of normalising it, but the primary effect of acupuncture on blood pressure is to lower it. This is a well attested outcome, and we have have seen thousands of patients over the years who have hypertension as a primary or secondary problem, many of whom have seen considerable improvements after treatment.
That is not to say that it cannot happen, and if you have come across some research which we have missed we would be very grateful for the reference. Things do change, and surprising results do emerge, but something as important as this would generally bubble to the surface quite quickly.
Our own fact sheet on hypertension is not as informative as some others we produce, and the evidence is not to the standard where we would be making specific claims for the benefits to be derived from treatment. Most of the studies, however, fail on methodological grounds, but all report a lowering of blood pressure with treatment.
