1. Overview
Irritable bowel syndrome (IBS) affects approximately 1 in 5 people in the UK and is characterised by abdominal pain, bloating, altered bowel habit, and a symptom pattern that fluctuates with stress and diet. Conventional medicine offers symptomatic management (antispasmodics, laxatives or anti-diarrhoeals, low-FODMAP diet) but no cure. Traditional Chinese medicine treats IBS by addressing the organ-system imbalances that produce the symptoms — producing meaningful long-term improvement in many patients. I am Dr (TCM) Attilio D’Alberto, with over 25 years of clinical experience treating IBS and digestive disorders.
2. Symptoms and subtypes
IBS is a clinical diagnosis (Rome IV criteria) made on the basis of symptoms and the exclusion of other conditions. The defining features are recurrent abdominal pain associated with defecation, change in stool frequency or change in stool form, present for at least 3 months. The four recognised subtypes are:
- IBS-D (diarrhoea-predominant) — loose stools, urgency, frequent bowel movements
- IBS-C (constipation-predominant) — hard or pellet-like stools, straining, sense of incomplete evacuation
- IBS-M (mixed) — alternating diarrhoea and constipation
- IBS-U (unclassified) — significant symptoms but does not fit the other patterns
Common associated symptoms include bloating, abdominal distension, mucus in the stool, post-prandial worsening, fatigue, and a strong correlation with stress and emotional state.
3. Causes and triggers
- Stress and the gut-brain axis — the single most consistent driver of IBS. Chronic stress alters gut motility, increases visceral hypersensitivity and changes the gut microbiome.
- Dietary triggers — FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides and polyols), gluten in some patients, caffeine, alcohol, large meals, fatty foods.
- Post-infective IBS — up to 30% of cases follow a gastroenteritis episode that disrupts the gut microbiome and intestinal nervous system.
- Hormonal fluctuation — many women report IBS symptoms worsening premenstrually.
- Antibiotic use — disrupts the microbiome.
- Anxiety and depression — share gut-brain pathways with IBS and frequently co-exist.
- Sleep disturbance — both a trigger and a consequence.
4. TCM patterns in IBS
Liver qi stagnation invading the Spleen
The most common pattern. Stress causes Liver qi to overact on the Spleen and Stomach, producing the characteristic IBS picture of abdominal pain relieved by defecation, bloating, alternating diarrhoea and constipation, and symptoms worsened by anxiety. The pulse is typically wiry on the Liver position and weak on the Spleen position; the tongue often shows a slightly red edge with teeth marks.
Spleen qi deficiency with dampness
Underlies the IBS-D (diarrhoea-predominant) subtype — loose stools, urgency, undigested food in stool, fatigue after eating, sweet cravings, abdominal heaviness. Spleen qi deficiency is often the consequence of chronic stress, poor diet (cold raw foods, excess sugar) or long-standing illness.
Spleen yang deficiency
A more advanced pattern with cold abdomen, watery diarrhoea worse in the early morning, cold extremities and pale tongue. Often seen in long-standing IBS-D, particularly with co-existing low body temperature and frequent urination.
Damp-heat in the Large Intestine
Urgent loose stools with burning sensation, possibly with mucus, sticky tongue coating, abdominal distension. Often follows infection or rich diet.
Liver qi stagnation with heat
Anger-driven flares, irritability, red tongue tip, bitter taste in the mouth, urgent loose stools after stressful events.
Kidney yang deficiency
In the chronic IBS picture with very early-morning diarrhoea (around 5am), cold lower back and weak knees.
5. Acupuncture for IBS
Acupuncture regulates gut motility, reduces visceral hypersensitivity and modulates the gut-brain axis. Research consistently shows significant symptom improvement for IBS with acupuncture compared with sham or conventional treatment, with sustained benefits at 6-month follow-up. Most patients see meaningful change within 6–8 weekly sessions, with continued improvement through 12 sessions. Key acupuncture points used include ST 25 (Tian Shu), ST 36 (Zu San Li), SP 6 (San Yin Jiao), LV 3 (Tai Chong) and CV 12 (Zhong Wan), individually selected based on the patient’s pattern.
6. Chinese herbal medicine
Chinese herbal medicine is one of the most effective treatments for IBS, with multiple high-quality clinical trials supporting its use. The classical formulae most commonly used:
- Tong Xie Yao Fang (Important Formula for Painful Diarrhoea) — the foundational formula for the Liver-Spleen disharmony pattern; has the strongest evidence base for IBS-D.
- Shen Ling Bai Zhu San — for Spleen qi deficiency with dampness.
- Xiao Yao San — for Liver qi stagnation with milder Spleen weakness.
- Li Zhong Wan — for Spleen yang deficiency with cold.
- Ban Xia Xie Xin Tang — for mixed cold-heat presentations with reflux and diarrhoea.
- Ma Zi Ren Wan — for IBS-C with dry stools.
- Si Shen Wan — for early-morning diarrhoea (Kidney yang deficiency).
I prescribe pharmaceutical-grade granules from Sun Ten in Taiwan, individually tailored to the patient’s presenting pattern and adjusted as the picture changes through treatment.
7. Diet and the TCM view
- Eat warm cooked foods — raw and cold foods (salads, smoothies, ice cream) weaken the Spleen and worsen IBS-D symptoms in TCM terms.
- Reduce dampness-promoting foods — dairy, wheat, refined sugar, fried foods, alcohol.
- Stable blood sugar — eat regular meals; avoid long fasts.
- Identify FODMAP triggers — a structured low-FODMAP elimination then reintroduction is the strongest dietary evidence base.
- Adequate fibre — soluble fibre (oats, psyllium, linseed) generally tolerated better than insoluble (wheat bran).
- Hydrate well — particularly in IBS-C.
- Eat slowly and chew thoroughly — supports the Spleen’s digestive function.
- Reduce caffeine and alcohol — both directly trigger IBS in many patients.
8. Lifestyle and stress management
- Daily 10–15 minutes of meditation, breathwork or yoga — the gut-brain axis is the central driver of IBS, and parasympathetic-activating practices directly reduce symptoms.
- Regular gentle exercise (walking, swimming, yoga) supports gut motility and reduces stress.
- Adequate sleep — 7–9 hours per night.
- Cognitive behavioural therapy (CBT) and gut-directed hypnotherapy have strong evidence for IBS and complement TCM treatment.
- Address co-existing anxiety or depression where present.
9. Supplements with evidence
- Peppermint oil (enteric-coated) — the strongest single-supplement evidence for IBS pain and bloating.
- Probiotic strains — particularly Bifidobacterium infantis 35624 and certain Lactobacillus strains; effects are strain-specific.
- Soluble fibre (psyllium) — well-supported for IBS-C; improves stool form in IBS-D too.
- Magnesium — mild laxative effect; useful in IBS-C.
- Vitamin D — deficiency is common in IBS; supplement to a level of 75–125 nmol/L.
- L-glutamine — supports gut barrier integrity in post-infective IBS.
- Curcumin — anti-inflammatory; some evidence in IBS.
10. When to see a doctor
See your GP urgently for any of the following “red flag” symptoms, which suggest a different diagnosis:
- New onset over the age of 50
- Unintentional weight loss
- Rectal bleeding (other than from haemorrhoids)
- Iron deficiency anaemia
- Family history of bowel or ovarian cancer
- Persistent change in bowel habit lasting more than 6 weeks
- Nocturnal symptoms (waking at night with pain or diarrhoea)
- Severe persistent abdominal pain
11. Frequently asked questions
Can Chinese medicine cure IBS?
IBS is a chronic condition rather than a curable disease, but the right combination of acupuncture, Chinese herbal medicine, diet and stress management produces substantial long-term improvement in most patients. Many patients achieve remission of significant symptoms with consistent treatment over 3–6 months.
How long does Chinese medicine take to work for IBS?
Most patients notice meaningful improvement within 6–8 weekly acupuncture sessions, with continued progress through 12 sessions. Chinese herbal medicine is usually taken daily for 3–6 months before tapering. Lifestyle and dietary changes typically show benefit within 4–6 weeks.
What is the best Chinese herbal formula for IBS?
For the Liver-Spleen disharmony pattern (the most common), Tong Xie Yao Fang has the strongest evidence base. Other patterns require different formulas; treatment must be individually prescribed based on a full TCM assessment.
Can acupuncture help IBS?
Yes. Multiple systematic reviews show acupuncture significantly reduces IBS symptoms compared with sham and conventional treatment, with sustained benefits at 6 months. It works by regulating gut motility, reducing visceral hypersensitivity and modulating the gut-brain axis.
Does the low-FODMAP diet work?
Yes — a structured low-FODMAP elimination followed by careful reintroduction has the strongest dietary evidence base for IBS. It is best done with the support of a registered dietitian. From a TCM perspective, low-FODMAP overlaps significantly with reducing dampness-generating foods.
Is IBS connected to stress?
Yes — the gut-brain axis is the central pathway in IBS, and stress is the single most consistent symptom trigger. In TCM terms, stress causes Liver qi stagnation that overacts on the Spleen, producing the classical IBS pattern. Stress management is central to long-term improvement.
