Gastrointestinal & Digestive Tract – Condition Resources

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.

Dyspepsia

The British Acupuncture Council has a Research digest where they have looked at some more recent studies including on Dyspepsia, including a 2-arm trial where the refractory functional dyspepsia patients were seen to experience improvement in symptoms for up to two months, with no adverse side effects (n=200) (Zheng et al, 2018).   An RCT in Korea (n=76) looked at functional dyspepsia as well as other quality of life related measures, finding a significant improvement in FD symptoms for up to 8 weeks in the acupuncture group (Ko et al, 2016).  

A meta-analysis of 16 RCTs (n=1436 total) found positive results both for symptoms and quality of life, albeit that the quality of the research was low in many cases in the trails they examined, but further high quality RCT studies are needed to corroborate the trends (Pang et al, 2016).

Irritable Bowel Syndrome

The British Acupuncture Council has a Research digest where they examined some recent studies on IBS, such as MacPherson et al (2017; n=116) in a follow up two years after their RCT acupuncture for IBS, finding a favourable result 24 months on.  Another RCT for diarrhoea type IBS (Zheng et al, 2016; n=448) found the acupuncture group found a level of improvement in line with that of the group assigned pharmacological (Loperamide) intervention in terms of reducing stool frequency.

Zhu et al (2018a) conducted a network meta-analysis of diarrhoea type IBS, with 29 studies (n=9369) entailed in it, finding that acupuncture may improve symptoms, but that further high quality research was needed to corroborate the overall results.  A meta analysis of diarrhoea predominant IBS (Deng et al, 2017) looked at 17 trials (n=1333), finding improvement in clinical symptoms in the acupuncture groups.

Similar trends have been seen in the trials for acupuncture in constipation predominant IBS, in a network meta-analysis, in which the quality of the trials was predominantly of high quality (40 trials n=11032; Zhu et al, 2018b). 

Constipation

The British Acupuncture Council has a Research digest where they examined some recent studies on constipation including an RCT taken in 15 hospitals in China (n=1075) where the acupuncture group was seen to increase the number of weekly spontaneous bowel movements, with the researchers recommending that further studies are needed to see the longer term outcomes (Liu et al, 2016). 

Another RCT (Zheng et al, 2018; n=684) similarly showed promise in this area, but was limited somewhat by its design in not having a sham acupuncture control (they only had three different types of verum acupuncture compared with pharmacological intervention), meaning it was difficult to know the magnitude of the effect.

A systematic review and meta-analysis of 33 trials (n=4324 total; Zheng et al, 2019) compared eight different non-drug treatments, finding acupuncture and TENS were the most effective in addressing chronic functional constipation symptoms, but interpreting the results with caution due to small study effects.
