Irritable bowel syndrome
Last updated: 2026-09-20 · Prepared by licensed TCM physicians · Updated 2026-09
Key Points
Irritable bowel syndrome (IBS) is a functional bowel disorder of recurrent abdominal pain with changed bowel habits (diarrhoea, constipation or alternation), with no structural cause found on testing.
- Affects about 1 in 10 people worldwide; slightly more women, often in young adults
- Rome IV centres on "recurrent abdominal pain related to defecation" as the key feature
- It links closely to a sensitised brain–gut axis, motility and microbiome shifts, and stress
- The WHO acupuncture list covers irritable bowel syndrome among conditions showing therapeutic effect
First, what cannot wait
- Blood in stool or black stools
- Progressive unexplained weight loss
- New bowel symptoms after 40 with no colonoscopy
- Waking at night with abdominal pain
- Persistent vomiting or worsening abdominal distension
- A clear change in pattern (sudden severe alternating diarrhoea/constipation)
- Anaemia, fever or marked fatigue
- No improvement after two weeks of diet and drug adjustment
Understanding the Condition
In plain words: the bowel is not damaged, but its "temper" is foul — it cramps with stress, rushes to the toilet with cold food, or withholds for days. Symptoms often ease after a bowel movement, a key clue.
It is not an infection or inflammatory bowel disease, but a state of "over-sensitive gut plus motility disorder" — like a violin string wound too tight, sounding at the lightest touch.
Why It Keeps Coming Back
Because triggers scatter through life: foods (gluten, lactose, high-FODMAP fermentable carbs), stress, sleep disruption, microbiome shifts — antidiarrheals or laxatives alone treat only the surface.
Many live the loop "the more anxious, the more the belly hurts; the more it hurts, the more anxious" — the brain–gut axis is central.
Our Pattern-Based Approach
TCM places IBS under "abdominal pain", "diarrhoea" or "constipation", by pattern. Common: liver stagnation with spleen deficiency — pain and diarrhoea with stress; spleen–stomach cold-deficiency — cold painful abdomen; spleen deficiency with dampness — sticky stools, heaviness; mixed cold-heat — upper discomfort with bowel sounds and loose stools.
Acupuncture regulates qi and strengthens the spleen: Tianshu (ST25), Zusanli (ST36), Shangjuxu (ST37), Taichong (LR3), plus diet and mood. We promise no "cure", only the change in pain frequency and bowel regularity over weeks.
Common patterns and treatment directions
| Pattern | Typical presentation | Approach |
|---|---|---|
| Liver stagnation with spleen deficiency | Abdominal pain and diarrhoea with stress, bowel sounds, wiry pulse | Course liver, strengthen spleen: Taichong (LR3), Zusanli (ST36), Pishu (BL20) |
| Spleen–stomach cold deficiency | Cold painful abdomen eased by warmth, loose stools | Warm centre, strengthen spleen: Zhongwan (CV12), Tianshu (ST25), moxa Shenque (CV8) |
| Spleen deficiency with dampness | Sticky unsatisfying stools, heaviness, greasy tongue coat | Strengthen spleen, resolve damp: Yinlingquan (SP9), Zusanli (ST36), Tianshu (ST25) |
| Mixed cold and heat | Upper discomfort, bowel sounds, loose stools, worsened by cold yet restless | Acrid-opening bitter-descending: Zhongwan (CV12), Shangjuxu (ST37), Neiguan (PC6) |
Patterns are determined in person. This list is for orientation only and is not a self-diagnosis tool.
The Evidence
- The 2003 WHO report lists irritable bowel syndrome among conditions where acupuncture's therapeutic effect has been shown (further proof needed) — a functional bowel disorder commonly addressed in clinic.

What to expect: first visit to follow-up
- First visit · about 40 minutesHistory, pulse, tongue and pattern; we review pain and stool patterns and any prior colonoscopy; red flags mean referral first.
- Plan discussion · same dayPattern, planned points and frequency, diet and stress points, and when to involve gastroenterology.
- Weeks 1-4One to two sessions per week to ease pain and steady bowel habits; you keep the diary and adjust diet.
- Week 4-6 · first reviewDiary data guide whether to continue, adjust points, or move to maintenance.
Course of care and follow-up
- Assessment usually runs in 4-6 week cycles
- After stabilising, maintenance every 2-4 weeks
- Re-assess pattern yearly or on symptom change
- Coordinate with gastroenterology; complete colonoscopy when indicated
When to Seek Care
Before your visit:
- Keep a food–symptom–stool diary to find personal triggers
- Regular sleep and meals; reduce high-FODMAP fermentable foods
- Learn relaxation training to manage stress and anxiety
Consider an in-person consultation if:
- New symptoms after 40 with no colonoscopy
- Blood in stool, black stools, weight loss or waking with pain at night
- Alternating diarrhoea/constipation with anaemia or fever
Supportive Care
- Set a regular toilet time; do not hold bowel movements
- Adjust fibre by type: less for diarrhoea, more for constipation
- Avoid very cold, fatty and known gas-producing foods
- Exercise and sleep: regular aerobic activity stabilises the gut–brain axis
FAQ
Can acupuncture stop my diarrhoea or constipation?
We assess pain frequency and bowel regularity over weeks, not a one-off fix. IBS is a manageable long-term state; the goal is fewer flares and better quality of life.
Does IBS turn into colitis or bowel cancer?
IBS does not become inflammatory bowel disease or cancer; but new onset after 40, or any alarm symptom, must first be ruled out by colonoscopy.
