IBS: Which Doctor to Consult, How It Is Diagnosed and What Treatment Works

01What is IBS?

IBS is a common disorder of the gut-brain interaction: the intestines are structurally normal, but their movement and sensitivity are altered. Typical symptoms are abdominal pain or cramping linked to passing stool, bloating, and a change in stool frequency or form. Doctors classify it as IBS-C (constipation), IBS-D (diarrhoea) or IBS-M (mixed). It is uncomfortable and can affect quality of life, but it does not damage the intestines or lead to cancer.

02Which doctor to consult for IBS

• Physician: a good first doctor for typical IBS symptoms in younger adults without warning signs.
• Gastroenterologist: for severe or persistent symptoms, uncertainty about diagnosis, or warning signs; can perform colonoscopy.
• Dietitian: for structured diets such as low-FODMAP.
• Psychologist or counsellor: for gut-directed therapy, stress and anxiety, which strongly influence IBS.

03Warning signs that need more tests

• Blood in stool or black stool.
• Unintentional weight loss.
• Anaemia.
• Symptoms starting after age 45–50.
• Diarrhoea waking you at night.
• Family history of colon cancer, coeliac disease or inflammatory bowel disease.
• Fever or a lump in the abdomen.

04How IBS is diagnosed

Diagnosis uses symptom criteria (recurrent pain at least one day a week for three months, related to stool) and a small set of tests to rule out look-alike conditions: blood count, thyroid, coeliac antibody test, stool tests for infection or inflammation (such as faecal calprotectin), and sometimes colonoscopy if warning signs are present. Many patients have had multiple scans and tests already; a clear diagnosis stops the cycle of repeated investigations.

05Diet strategies that help

• Regular meals; avoid skipping or overeating.
• Identify triggers: common ones are fried and spicy food, excess tea/coffee, alcohol, carbonated drinks, and for some, milk.
• Soluble fibre such as isabgol helps both constipation and diarrhoea types; insoluble bran can worsen bloating.
• A low-FODMAP diet (temporarily reducing certain fermentable carbohydrates found in onions, garlic, wheat, some fruits and beans), guided by a dietitian, helps many people.
• Adequate water and probiotic curd.

06Stress, sleep and the gut-brain axis

The gut and brain communicate constantly. Stress, anxiety and poor sleep amplify gut sensitivity and change bowel movements — which is why IBS often flares during exams, work pressure or family stress. Regular exercise, yoga, breathing practice, adequate sleep and, when needed, cognitive behavioural therapy or gut-directed hypnotherapy significantly reduce symptoms.

07A practical IBS food plan to start

• Breakfast: oats or poha with curd, or idli with sambar made with less onion.
• Lunch: rice or two chapatis, moong dal, a cooked vegetable such as lauki, tinda, carrot or pumpkin.
• Snack: banana, papaya, or roasted makhana.
• Dinner: light khichdi or vegetable soup with paneer or fish; finish 2–3 hours before bed.
• Through the day: water, buttermilk; limit tea and coffee; avoid fizzy drinks.

If milk worsens symptoms, try curd or lactose-free milk. Bring a two-week food and symptom diary to your consultation.

08IBS-D vs IBS-C: different strategies

In IBS with diarrhoea, reducing caffeine, alcohol, spicy and fatty foods, and certain fermentable carbohydrates helps; soluble fibre can firm stools; and medicines that slow the gut or calm gut nerves may be used. In IBS with constipation, soluble fibre, water, physical activity and osmotic laxatives form the base, with newer prescription medicines for resistant cases. Mixed IBS needs a flexible plan adjusted during flares.

09IBS or something else? Conditions doctors rule out

Coeliac disease, inflammatory bowel disease, thyroid disorders, lactose intolerance, intestinal infections such as giardia, bile acid diarrhoea and, in older adults, bowel cancer can mimic IBS. Women with bloating and pelvic symptoms may need ovarian assessment. This is why a few targeted tests at the start are worthwhile — and why "IBS" should be confirmed by a doctor rather than self-diagnosed.

10Yoga and exercise for IBS

Regular moderate exercise improves bowel movement and reduces stress. Yoga practices such as pawanmuktasana, balasana, gentle twists and slow breathing have shown benefit for IBS symptoms in studies. Aim for 30 minutes most days, and avoid intense workouts immediately after meals.

11Medicines for IBS

Depending on the type, doctors may use antispasmodics for cramps, laxatives or soluble fibre for IBS-C, antidiarrhoeal medicines for IBS-D, low-dose medicines that modulate gut nerves, and specific gut-acting antibiotics in selected cases. Medicines are chosen to match your main symptom and reviewed after a few weeks.

12Living with IBS

IBS often comes and goes. Keep a symptom and food diary, plan meals, carry a light snack when travelling, and find a routine that works for your bowels. A doctor who listens and adjusts treatment over time is more valuable than a one-time prescription.
