Acupuncture for IBS and Bloating in Denver

Read the source: open the record

Design

Randomized trial in 6 hospitals in China. Adults aged 18 to 75 with IBS-D (Rome IV criteria) were assigned 1 to 1 to 15 sessions of acupuncture or imitation acupuncture (a blunt-tipped needle at non-acupoints) over 6 weeks, with 12 weeks of follow-up.

Result

The main goal was at least 30% less worst belly pain and at least half as many days with diarrhea at week 6. It was reached by 71 people (57.9%) with acupuncture and 47 people (41.4%) with imitation acupuncture (risk ratio 1.40, P = .008). The gap was significant from week 3 and held through the study except at week 16. No severe adverse event was reported.

Limit

It tested IBS with diarrhea only, so it says nothing about IBS-C or mixed IBS. About 4 in 10 people in the imitation group also reached the goal, which shows how strong the placebo response can be.

Design

Randomized trial in 7 hospitals in China. People with IBS (Rome III criteria) were split into IBS-C and IBS-D groups, then assigned 2 to 1 to 18 sessions of acupuncture over 6 weeks, or to a drug: polyethylene glycol 4000 (20 g a day) for IBS-C or pinaverium bromide (150 mg a day) for IBS-D. Follow-up lasted 12 weeks. Of 531 people randomized, 519 were analyzed.

Result

The IBS symptom severity score fell by 123.51 points with acupuncture and 94.73 points with the drugs. The difference was 28.78 points (95% CI 16.84 to 40.72, P < .001). The authors say acupuncture may be more effective than the drugs, with effects lasting up to 12 weeks. No one had a severe adverse effect.

Limit

Acupuncture was compared with drugs, not imitation acupuncture, so expectations may have played a part. The abstract does not give separate results for IBS-C and IBS-D.

Design

Network meta-analysis of 25 randomized trials (3,041 people) of acupuncture alone, or added to usual care, for IBS. Three databases were searched to 1 July 2021. The main outcome was improvement in overall IBS symptoms.

Result

Manual acupuncture plus usual care ranked most effective (RR 1.96, 95% CI 1.23 to 3.12, with imitation acupuncture as the common comparison). When added to usual care, manual acupuncture was the most effective part (RR 1.38, 95% CI 1.12 to 1.70).

Limit

Only 5 of the 25 trials had a low risk of bias. The authors call the benefit of acupuncture alone controversial, and suggest it as an add-on for people who respond poorly to usual care.

Design

Meta-analysis of 61 randomized trials of acupuncture for functional gut disorders, including indigestion, IBS and constipation. Seven databases were searched through December 2019.

Result

Symptoms improved more with acupuncture than with medicine (RR 1.13, 95% CI 1.09 to 1.17), imitation acupuncture (RR 1.69, 95% CI 1.37 to 2.08) and no specific treatment (RR 1.86, 95% CI 1.31 to 2.62). Adding acupuncture to other active treatments also helped (RR 1.25, 95% CI 1.21 to 1.30). The IBS subgroup supported this finding. Adverse events were less common with acupuncture (RR 0.75, 95% CI 0.56 to 0.99).

Limit

The authors rate the evidence as moderate or low. The abstract gives no numbers for IBS alone.

Design

Pilot randomized trial in 4 hospitals in China. 90 people with IBS-D (30 per group) had twelve 30-minute sessions over 4 weeks, 3 a week. The groups were acupuncture at specific points, acupuncture at nonspecific points, or imitation acupuncture at non-acupoints.

Result

The main goal was reached by 46.7% (specific points), 46.7% (nonspecific points) and 26.7% (imitation) of people. The gap was not statistically significant (P = .18). Adequate relief was reported by 64.3%, 62.1% and 55.2% (P = .76). Adverse events occurred in 2 people (6.7%) in the specific-points group and 3 people (10%) in the other groups.

Limit

It was a pilot trial. The authors say acupuncture looked feasible and safe, and that a larger trial is needed to judge whether it works.

Design

Meta-analysis of 31 randomized trials of acupuncture and moxibustion for IBS, searched to 30 June 2022. Risk of bias was rated with the Cochrane tool and certainty with GRADE.

Result

Acupuncture lowered symptom severity more than drugs (mean difference -35.45, 95% CI -48.21 to -22.68). Against imitation acupuncture it did not lower overall symptom severity (SMD 0.03, 95% CI -0.25 to 0.31), but belly pain was slightly lower (SMD -0.24, 95% CI -0.48 to -0.01). Moxibustion beat imitation moxibustion, but results varied widely between trials.

Limit

The authors say acupuncture has not shown robust, stable evidence in imitation-controlled trials, and call for more rigorous trials.

Design

Cochrane review of 17 randomized trials (1,806 people) of acupuncture for IBS in adults, compared with imitation acupuncture, other treatments or no specific treatment. Databases were searched through November 2011.

Result

In 5 trials against imitation acupuncture there was no gain for symptom severity (SMD -0.11, 95% CI -0.35 to 0.13, 4 trials, 281 people) or quality of life (SMD -0.03, 95% CI -0.27 to 0.22, 3 trials). Against drugs, 84% of the acupuncture group improved versus 63% (RR 1.28, 95% CI 1.12 to 1.45, 5 studies, 449 people). Against no specific treatment, 63% improved versus 34% (RR 2.11, 95% CI 1.18 to 3.79, 2 studies). There was no difference from Bifidobacterium or psychotherapy. One adverse event (fainting) was reported across the 9 trials that reported adverse events.

Limit

The imitation-controlled trials had a low risk of bias, and the authors rated their evidence moderate. The drug comparisons had a high risk of bias because no one was blinded, and the evidence was rated low. The search ended in 2011, before the newer trials.

Design

Single-blind randomized trial in Chinese adults with both generalized anxiety disorder and IBS. 80 people (40 per group) had 10 weekly sessions of electroacupuncture or imitation electroacupuncture. The main outcome was anxiety.

Result

A drop of at least 50% in anxiety occurred in 32.4% versus 21.6% right after treatment (P = 0.06) and 25.7% versus 27% at 6 weeks (P = 0.65). Anxiety, depression and bowel symptom severity did not differ between groups.

Limit

Only people with both conditions took part, and the main outcome was anxiety, not gut symptoms. The authors say other acupuncture protocols may still be worth studying.

Design

Review of 15 systematic reviews of acupuncture and moxibustion for IBS, published before 20 February 2023. Eight databases were searched. Method quality, reporting and evidence quality were scored with AMSTAR 2, PRISMA 2020 and GRADE.

Result

Method quality was low in 2 reviews and very low in 13. Evidence quality was low or very low. Most reviews interpreted their findings as showing benefit for IBS.

Limit

This study judges the quality of the reviews, not how well acupuncture works for any one person. The authors call for larger, rigorous trials and better reviews.

Design

The first American College of Gastroenterology guideline for IBS, built with GRADE methods. It covers 25 questions: 9 on diagnostic testing and 16 on treatment.

Result

It suggests a positive diagnosis rather than diagnosis by exclusion. It suggests celiac disease blood tests and a stool calprotectin test (a marker of bowel inflammation) in people with diarrhea symptoms. It recommends a limited trial of a low FODMAP diet to improve overall symptoms, and suggests gut-directed psychotherapy. It recommends specific medicines for IBS-C (chloride channel activators and guanylate cyclase activators) and rifaximin for IBS-D.

Limit

The published summary does not mention acupuncture. I include it as context for your overall care, not as a verdict on acupuncture.

The evidence is mixed. In a 2025 trial of 280 people with IBS and diarrhea, 57.9% reached the main goal with acupuncture, versus 41.4% with imitation acupuncture. A 2012 Cochrane review of 17 trials found no gain over imitation acupuncture, and a 2022 pilot trial of 90 people found no clear gap. I use acupuncture as one part of your care, alongside your doctor, not as a replacement.

The three trials in IBS that stated a count used 12 to 18 sessions over 4 to 6 weeks. A fourth trial, in people with both IBS and anxiety, used 10 weekly sessions. After your first five visits, I review your progress with you. If your symptoms have not changed by then, I tell you.

Most of the newest evidence is for IBS with diarrhea (IBS-D). The 2025 and 2022 trials only included people with IBS-D. A 2020 trial of 519 people included both IBS-C and IBS-D, but its abstract does not give results for each type. So I cannot say acupuncture works better for one type. I choose points based on your symptoms, whether you have diarrhea, constipation or both.

Many people with IBS feel bloated, but the abstracts I reviewed do not report bloating results. The trials measured belly pain, stool habits and overall symptom scores. I cannot promise acupuncture will ease bloating. Please see your doctor first if bloating is new, constant or comes with weight loss, blood in your stool or belly swelling.

Acupuncture is considered among the safer treatments in medicine. A review of 21 prospective studies found serious side effects in about 1 in 10,000 patients, and about 9 in 100 noticed a minor effect, such as a little bleeding or soreness at a needle site. The Cochrane review found one adverse event, fainting, in the 9 trials that reported adverse events. Please tell me if you take blood thinners, have a bleeding disorder or have a pacemaker.

Yes. The 2021 American College of Gastroenterology guideline recommends a limited trial of a low FODMAP diet to improve overall IBS symptoms. FODMAPs are types of carbohydrate that some people digest poorly. Please work with your doctor or a dietitian on the diet, and keep taking your medicines unless your doctor changes them. I do not replace either one.

See your doctor first for blood in your stool or black stools, weight loss you did not plan, fever, belly pain or diarrhea that wakes you at night, vomiting that does not stop, or new bowel symptoms after age 45. IBS is a diagnosis for your doctor to make, because other conditions can look the same. The 2021 ACG guideline suggests celiac disease blood tests and a stool calprotectin test in people with diarrhea symptoms. If you have any of these symptoms and have not already told your doctor, please let them know.
