Irritable Bowel Syndrome is a chronic disease of unknown causes, which manifests itself in abdominal pain and alteration of bowel habits. The above symptoms do not result from any organic or biochemical changes.  It is estimated that these dysfunctions of the gastrointestinal tract concern about every tenth person (source)1. Because the primary cause has not been determined, classic treatment concentrates on relieving its symptoms and thus has a limited effectiveness. That is why patients seeking help aim at non-standard methods of therapy. Chinese medicine which focuses to a great extent on dietary recommendations, herb therapy, and which acknowledges emotional factors as a significant cause of diseases has a lot to offer to patients suffering from Irritable Bowel Syndrome. One of the treatment methods is acupuncture, which is becoming more and more popular.

Until recently evidence provided by research led to divergent conclusions. A report published in 2012 by researchers from Cocharane Baze did not give definite conclusions, however, the results of the conducted analyses showed the effectiveness of acupuncture which was higher than chemical medicines or a lack of treatment (source)2.

Meanwhile the latest meta-analysis, carried out extremely rigorously, published by World Journal of Gastroenterology in February 2014, which included 6 randomized, placebo controlled clinical studies, which obtained more than 3 points in JADAD scale, clearly shows that acupuncture leads to the control of the IBS symptoms, which is both statistically characteristic and clinically significant (source)3. It is worth mentioning that two of the included studies were from the USA and Great Britain, and one from Canada and China.

Various hypotheses have been tested while looking for mechanisms which are involved in such a positive effect of acupuncture on functional disorders of the gastrointestinal tract.   Researchers from Hong Kong in the experiment with the use of functional magnetic resonance imaging have proved that relieving the symptoms of Irritable Bowel Syndrome occurs via modulation of serotonin pathway in the insula, as well as the influence on the mood and passion in the higher cerebral cortex via the ascending pathway in the nuclei of thalamus (source)4.

In a study on an animal model a significant influence of acupuncture has been shown on the levels of Y neuropeptide in the thalamus and somatostatin in the bowels tissue (source)5.       A different study has shown that electro-acupuncture decreases Fos expression in the dorsal raphe nucleus, posterior horn of spinal cord and intestine epithelium, and also serotonin expression in the brain stem and spinal cord, which confirms the role of the serotonin path in a positive IBS patients’reaction to acupuncture (source)6.

In 2013 a meta-analysis was published concerning moxibustion in Irritable Bowel Syndrome, which included 20 randomized, controlled clinical studies comprising totally the number of 1625 patients (source)7. The results of this meta-analysis show that moxibustion is beneficial for people suffering from Irritable Bowel Syndrome, nevertheless, the authors of the paper indicate that the risk of bias is relatively high.

Because of a high clinical usefulness of moxibustion and its popularity in the Asian countries,  its mechanisms of affecting visceral pain are being investigated. In experiments on animal models it has been proved that it reduces chronic visceral pain through the activation of serotonin path and the reduction of serotonin concentration in the intestines (source)8. It has also been proved that moxibustion reduces mRNA expression for corticoliberin –a corticotrophin-releasing hormone in the thalamus (source)9. Another mechanism studied on animals, which explains a positive effect of moxibustion on the IBS symptoms is the activation of medullary dynorphines and the system of nociceptin/orphanin FQ(source)10.

As it has been mentioned in the article on an economic legitimacy of acupuncture, in case of Irritable Bowel Syndrome acupuncture as an additional method of treatment turns out to be economically justified in patients with the highest intensity of symptoms (source)11.
