IBS is a common, long-term condition that causes tummy pain, bloating and changes in bowel habit — diarrhoea,
constipation or both. Tests are normal because the problem lies in how the gut and brain communicate, not in
visible damage. IBS doesn't lead to cancer or other serious disease, and most people find a combination of diet,
stress management and simple treatments that keeps it under control. Ayurveda describes a closely related condition,
Grahani.
What is IBS?
The gut has its own network of nerves that is in constant two-way contact with the brain. In IBS, this
gut–brain axis is oversensitive: normal amounts of gas and movement are felt as pain, and bowel movements
speed up or slow down. Triggers include certain foods, stress and anxiety, hormonal changes around periods, and a
previous bout of gastroenteritis — about 1 in 10 people develop IBS after food poisoning or “traveller's
diarrhoea”. It affects around 1 in 10 adults, more women than men, usually starting before 50.
Freshly cooked, simply spiced meals eaten at regular times are the foundation of Ayurvedic care for digestion (agni).
Symptoms & types
Abdominal pain or cramps, often eased by opening the bowels
Bloating and a swollen tummy, often worse through the day
Diarrhoea, constipation, or alternating between the two
Urgency, a feeling of incomplete emptying, mucus in the stool
Tiredness, nausea, backache and bladder symptoms can accompany it
IBS is grouped by the main bowel pattern: IBS-D (diarrhoea), IBS-C (constipation) and IBS-M (mixed). The type guides treatment.
Signs that need tests
These are not typical of IBS. See a doctor promptly if you have:
Blood in the stool or black stools
Unintended weight loss, anaemia, or fever
Symptoms that wake you from sleep
New bowel symptoms starting after the age of 50
A family history of bowel cancer, inflammatory bowel disease or coeliac disease
A lump in the abdomen; women over 50 with persistent bloating
Diagnosis & treatment
IBS is diagnosed from the typical pattern of symptoms, plus a few tests to rule out other conditions: blood count,
CRP, coeliac antibodies, and often a stool test (faecal calprotectin) to exclude inflammatory bowel disease; stool
tests for parasites are useful in India. Colonoscopy is needed only if there are warning signs. Treatment is
tailored:
Diet — regular meals, adjusting fibre, and if needed the low-FODMAP approach below
Soluble fibre such as isabgol (psyllium) helps both constipation and diarrhoea; coarse bran often worsens bloating
Antispasmodics and peppermint oil capsules for cramps
Loperamide for diarrhoea; laxatives for constipation
Low-dose gut–brain medicines (such as amitriptyline) that calm gut nerve sensitivity — used for pain, not because the pain is imagined
Psychological therapies — CBT and gut-directed hypnotherapy have good evidence
The low-FODMAP diet
FODMAPs are types of carbohydrate that are poorly absorbed and fermented by gut bacteria, producing gas and
drawing water into the bowel. Common sources include wheat, onions, garlic, beans and lentils, milk, some fruits
(apples, mangoes, watermelon) and sweeteners. The diet is a short-term test, not a permanent restriction, and works
best with a dietitian.
Long-term strict restriction is not recommended — it narrows the diet and can harm gut bacteria.
Low-FODMAP swaps common in Indian kitchens: rice, millets, oats, moong dal in small portions, hing (gluten-free) instead of onion and garlic, lactose-free milk or curd, papaya, orange and banana (firm).
Ayurvedic view
Strengthen digestive fire (agni) → clear ama → settle Vata in the gut and mind → restore the Grahani (small intestine) to its role of holding and digesting food.
In Ayurveda, Grahani is both an organ — the part of the gut that “holds” food until it is digested — and a
disease in which weakened digestion causes stools that are sometimes loose, sometimes hard, with pain, gas and
mucus. Charaka Samhita emphasises that weak agni, irregular meals and emotional stress
(worry, fear, grief) cause it — an early description of the gut–brain link. Buttermilk (takra) is regarded
as the finest food for Grahani.
Herbs & safety
Food as medicine
Takra (buttermilk)
Thin buttermilk with roasted cumin, a pinch of rock salt and ginger, after lunch. Usually well tolerated even with lactose sensitivity.
Diarrhoea-type
Bilva & Kutaja
Unripe bael fruit (bilva) and Kutaja are classical for loose stools with mucus.
Constipation-type
Isabgol & Triphala
Psyllium husk with water, or Triphala at bedtime, on a practitioner's advice.
Evidence for Ayurvedic IBS treatments is limited to small studies. Brahmi or Ashwagandha for
stress can add to the effect of sedating medicines. Don't treat new diarrhoea with blood, fever or weight loss
yourself — see a doctor first. Use licensed products from a qualified practitioner.
Daily habits
Eat at regular times; don't skip meals or eat very late; chew slowly.
Keep a food-and-symptom diary for a few weeks to spot patterns.
Limit tea and coffee to 3 cups a day, and cut down on alcohol, fizzy drinks, spicy and fried food.
For diarrhoea, reduce insoluble fibre (skins, seeds, bran); for constipation, increase soluble fibre and fluids gradually.
Exercise regularly — walking and yoga reduce IBS symptoms.
Manage stress with slow breathing, Yoga Nidra or meditation; seek help for anxiety or low mood.
