Important to know: Chronic health conditions should be addressed under direct medical supervision of your GP or consultant, and acupuncture would be an adjunct or complement to usual care – we advise that you let you doctor know when you use this approach.
About the research: It is worth noting that in research, randomised controlled studies (RCT) are the most reliable in terms of quality of evidence, with a systematic review or meta analysis of numerous studies being the best way of seeing the overall picture of the state of the evidence. Below we have a selection of the available research, which does include some larger RCTs, and reviews of the literature alongside smaller studies. The n= figure tells you how many people were participants in the study.
