Gut problems like bloating, gas, constipation and diarrhoea are extremely common. Here's what "gut health" really means, how to tell if it's IBS, which tests are actually useful, and what helps — on a diet that works for India.
What Is Gut Health?
"Gut health" generally refers to the health of the digestive tract and the trillions of microorganisms (the gut microbiome) that live in it. Symptoms of a troubled gut include:
- Bloating and gas
- Constipation or diarrhoea
- Abdominal pain and cramping
- Heartburn or acid reflux
- Feeling full quickly or nausea
A healthy gut digests food well, absorbs nutrients, and supports a balanced microbiome that interacts with the immune system and even the brain (the gut-brain axis).
Irritable Bowel Syndrome (IBS)
IBS is a chronic disorder of how the gut and brain interact. It is a "functional" disorder — meaning tests usually look normal, but the gut doesn't function comfortably. In India, community studies suggest IBS affects around 0.4%–4.2% of people, though urban surveys report higher numbers — the variation depends heavily on which diagnostic criteria are used (INMA/ISG Indian IBS consensus 2023).
- Symptoms: recurrent abdominal pain related to bowel movements, plus changes in stool frequency or form — constipation (IBS-C), diarrhoea (IBS-D), or mixed (IBS-M).
- Other features: bloating, mucus in stool, urgency, and the feeling of incomplete emptying.
- Not the same as: inflammatory bowel disease (IBD, such as Crohn's and ulcerative colitis) or coeliac disease. These are different conditions that cause inflammation or damage and need separate treatment.
Diagnosing IBS
There's no single blood or stool test for IBS — diagnosis is based on symptoms (the Rome criteria) after ruling out other causes (INMA/ISG Indian IBS consensus 2023). A doctor usually:
- Takes a careful history and checks for "red flag" symptoms.
- May order blood tests (such as a CBC, CRP, and TSH), a stool test, or imaging to rule out other causes.
- Can apply a symptom-based set of criteria (the Rome criteria) to confirm the diagnosis.
Red flag symptoms that need prompt evaluation (and are NOT typical IBS):
- Bleeding from the rectum or black, tarry stools
- Unexplained weight loss
- Fever
- Anaemia
- Symptoms starting after age 45 (Indian consensus sets the threshold at 45, slightly earlier than the Western figure of 50)
- A family history of colon cancer or IBD
- Pain that wakes you at night
What Causes IBS?
IBS is thought to result from a mix of factors:
- Gut hypersensitivity — the gut is more sensitive to normal stimuli.
- Abnormal gut motility — food moves too fast or too slow.
- Gut-brain interaction — stress and emotions worsen symptoms. In Indian studies, anxiety and depression are significantly more common in people with IBS (INMA/ISG Indian IBS consensus 2023).
- Diet — certain foods trigger symptoms in sensitive individuals.
- Changes in the microbiome, including small intestinal bacterial overgrowth (SIBO), which Indian consensus research reports in over a third of IBS patients (INMA/ISG Indian IBS consensus 2023).
- A past gut infection — some people develop IBS after a bout of gastroenteritis. This includes post-COVID IBS: an Indian case-control study found it in about 5% of people six months after COVID-19 (Post-COVID IBS review).
Which Tests Are Actually Useful?
Because there's no single IBS test, testing is mainly about ruling out other conditions:
- Basic blood tests — a full blood count (CBC), C-reactive protein (CRP), and TSH help rule out anaemia, inflammation, and thyroid problems.
- Coeliac screen (tTG-IgA blood test) — India checks for coeliac disease before labelling gut symptoms as IBS, because it's more common than often assumed.
- Fecal calprotectin (stool test) — measures gut inflammation and helps separate IBS from inflammatory bowel disease. In India it typically costs around ₹1,500–₹4,000 depending on the lab; check your lab's current price.
- Breath tests — hydrogen/methane breath tests can help identify lactose intolerance or SIBO in people with bloating and diarrhoea.
Talk to your doctor about which, if any, of these make sense for you. A colonoscopy is only needed if red-flag symptoms are present.
Indian Diet and Lifestyle Strategies That Help
1. Eat More Fibre (Gradually)
- Soluble fibre (in oats, bananas, isabgol/psyllium, moong dal) is generally best-tolerated for IBS.
- Increase fibre slowly over a few weeks, and drink more water. Isabgol/psyllium husk is a well-studied soluble fibre choice for constipation-predominant IBS — Indian consensus guidance notes a dose of around 20 g a day (INMA/ISG Indian IBS consensus 2023). Start small and let your doctor guide the dose.
2. The Low-FODMAP Diet (Under Guidance)
FODMAPs are fermentable carbohydrates that can trigger symptoms in people with IBS.
- What it involves: a short-term (2–6 week) elimination of high-FODMAP foods, followed by a structured reintroduction, under a trained dietitian.
- High-FODMAP foods to learn about: certain fruits (apple, mango in excess), onion, garlic, beans and lentils, wheat, milk (lactose), and sweeteners.
- An Indian twist: typical North Indian dishes tend to be higher in FODMAPs (onion, garlic, legumes, wheat), while South and Northeast Indian cooking is often lower. Simple swaps can help — for example, tempering with hing (asafoetida) instead of onion and garlic, and choosing moong dal over rajma or chole in larger portions.
- Important: this is not a forever diet and not to be done alone — it needs expert guidance to stay balanced. Prolonged strict restriction can reduce dietary variety and affect quality of life, and many people improve with simpler first-line changes (fibre and trigger avoidance) before ever needing FODMAP elimination. The evidence for low-FODMAP in Indian diets is still building.
3. The Curd (Dahi) Question
- Fermentation lowers the lactose in curd, so it's often better tolerated than milk for mild lactose sensitivity.
- But homemade curd isn't a clinically proven probiotic — the helpful bacteria may not survive digestion, and doses/strains aren't standardised.
- For many with IBS, a small amount of dahi or chaas is fine; in others, any dairy triggers symptoms. Indian expert consensus only weakly endorses probiotics for IBS, so let food tolerance and your doctor guide you.
- Traditional fermented Indian foods (idli, dosa, chaas, kanji) are a reasonable part of a varied gut-friendly diet.
4. Avoid Personal Trigger Foods
Common individual triggers in IBS:
- Spicy or very fatty foods
- Caffeine and carbonated drinks
- Large meals
- Artificial sweeteners (sorbitol, xylitol)
5. Eat Regularly and Slowly
- Have regular meals; don't skip meals.
- Eat slowly and chew well.
- A food diary (what you ate, when, and your symptoms) helps identify personal triggers.
6. Manage Stress and Stay Active
- Relaxation, deep breathing, and regular physical activity help. Yoga and other stress-reduction practices can improve IBS symptoms for many people.
- Cognitive behavioural therapy (CBT), gut-directed hypnotherapy, and mindfulness-based stress reduction have evidence for IBS and can be paired with medical care.
Medications and Treatments
Treatment depends on the dominant symptom and is guided by a doctor:
- Laxatives (including isabgol/psyllium) for constipation-predominant IBS
- Anti-diarrhoeal agents for diarrhoea-predominant IBS
- Antispasmodics for cramping pain
- Antidepressants in low doses — these can help the gut-brain interaction even when mood isn't the issue
- Gut-directed therapies (CBT, hypnotherapy)
- Antibiotics like rifaximin — for selected cases (e.g., SIBO), under specialist care
Don't self-medicate long-term with laxatives or over-the-counter products without a doctor's guidance.
Can IBS Be Cured?
There's no permanent cure, but many people with IBS achieve long-term control in remission with the right combination of diet, stress management, lifestyle, and — when needed — medication. The goal is long-term management, not a one-off fix, and most people can find a plan that works.
When to See a Doctor
See a doctor if you have any of the red flag symptoms above, or if gut symptoms are persistent and affect your quality of life, work, or sleep. Persistent symptoms deserve a proper evaluation rather than years of self-treatment. If first-line diet, lifestyle, and medication aren't enough after a few months, ask for a referral to a gastroenterologist or a gut-directed psychologist.
Key Takeaways
- IBS is a real, common condition of the gut-brain interaction — not "all in your head," and current evidence does not show it raises your risk of colon cancer (Mayo Clinic).
- There's no single diagnostic test; doctors rule out other causes with selected blood and stool tests.
- Diet (fibre, low-FODMAP where suitable, trigger avoidance), stress management, and activity are the foundations of relief.
- Testing is about excluding other conditions — let a doctor decide which tests you need, and book them with a NABL-accredited lab with home collection if convenient.
