Frequently Asked Questions

Expert answers from our medical team

What is IBS and how is it diagnosed?

Irritable Bowel Syndrome is a functional disorder — abdominal pain plus altered bowel habits (diarrhoea, constipation, or both) with no visible damage to the gut. Diagnosis is clinical, based on symptom patterns (Rome criteria) after ruling out other conditions. There's no single blood test or scan. In India, IBS is often over-medicated and under-explained; a good gastroenterologist takes time to explain the diagnosis.

What triggers IBS symptoms?

Common triggers include specific foods (a low-FODMAP diet helps many patients), stress, poor sleep, hormonal cycles in women, and gut infections that don't fully clear (post-infectious IBS). Everyone's triggers are different — keeping a food and symptom diary for 2-4 weeks often reveals patterns.

Can IBS be cured?

Not cured, but well-managed. Most people with IBS find a combination of dietary changes, stress management, targeted medication for symptoms (antispasmodics for pain, fibre or laxatives for constipation, anti-diarrhoeals for loose stools), and sometimes low-dose antidepressants — which act on the gut-brain axis — brings symptoms under control. Cognitive behavioural therapy and gut-directed hypnotherapy have solid evidence for IBS too.

Should I try the low-FODMAP diet?

It's the most evidence-backed dietary approach for IBS, but it's a temporary elimination and reintroduction process — not a permanent diet. Doing it right needs a dietitian familiar with FODMAPs (many foods common in Indian diets — wheat, onions, garlic, some pulses — are high FODMAP). Poorly done, it becomes unnecessarily restrictive.

Is IBS all in my head?

No. IBS is a real, physical condition — the gut is genuinely oversensitive and the muscle contractions are genuinely abnormal. What's true is that the gut and brain are tightly connected: stress worsens symptoms, and symptoms worsen stress. Treating both sides of that loop — dietary and physical, plus stress and mood — usually works better than either alone.
