IBS (Irritable Bowel Syndrome) – Why It’s Rising Fast Among Young Indians, and What Actually Helps in Ahmedabad
What Is IBS — and Why Is It Rising Among Young Indians in 2026?
Irritable Bowel Syndrome (IBS) is a chronic functional disorder of the gut — meaning the digestive tract looks structurally normal on scans and endoscopy, yet does not function normally. The gut-brain communication that controls digestion, motility and sensation becomes disrupted, leading to recurring abdominal pain, bloating, and altered bowel habits without any visible disease, inflammation, or damage.
IBS has traditionally been considered a condition of middle age, but that picture is changing quickly. Gastroenterologists across Indian metros — including Ahmedabad — are reporting a sharp rise in IBS diagnoses among people in their twenties and early thirties. The contributing factors are consistent with the pace of modern urban life: irregular eating schedules driven by long work hours, high consumption of ultra-processed and packaged food, chronic sleep disruption, and levels of workplace stress that were far less common a generation ago.
According to research published by the National Institutes of Health (NIH), IBS affects an estimated 10 to 15 percent of the global population, with prevalence in India reported to be on the higher end of that range in urban populations — driven significantly by dietary and lifestyle factors specific to city living.
The Four Types of IBS — Which One Do You Have?
IBS is not a single, uniform condition. It is classified into subtypes based on the predominant bowel pattern, because this classification directly determines the most effective treatment approach.
Hard, lumpy stools, infrequent bowel movements, and straining are the dominant pattern. More common in women. Often accompanied by a persistent sensation of incomplete emptying.
Loose or watery stools, urgency, and frequent bowel movements dominate. Often triggered suddenly by meals, stress, or specific foods. Can be significantly disruptive to work and travel.
Alternating between constipation and diarrhoea, sometimes within the same week. This is one of the most common presentations and can be the most confusing for patients to self-manage.
Bowel habits do not fit clearly into the above categories, but abdominal pain and altered bowel function are still clearly present and impact daily life.
Symptoms of IBS You Should Recognise
IBS symptoms vary from person to person, but certain patterns are consistently reported across most cases. Recognising these patterns is often the first step toward seeking a proper evaluation instead of continuing to self-manage indefinitely.
Cramping or aching pain, typically in the lower abdomen, that is associated with bowel movements — often improving somewhat after passing stool, then returning later.
A sensation of fullness or swelling in the abdomen, often worsening as the day progresses. Many people notice their trousers feel tighter by evening despite no weight change.
Diarrhoea, constipation, or an unpredictable alternation between the two. The pattern itself, and how consistently it recurs, is central to how IBS is diagnosed.
Increased gas production, often linked to specific trigger foods, and frequently a source of significant embarrassment and social anxiety for those affected.
Passing visible mucus with bowel movements is common in IBS and, on its own without other alarm symptoms, is not a sign of a more serious underlying condition.
A persistent feeling that the bowel has not been fully emptied, even immediately after a bowel movement — common in both the constipation and mixed subtypes.
A clear pattern where certain foods, periods of high stress, or hormonal changes around the menstrual cycle noticeably worsen symptoms for several days at a time.
Chronic discomfort, disrupted sleep from nighttime symptoms, and the mental load of managing unpredictable symptoms often lead to persistent tiredness that is frequently overlooked as IBS-related.
IBS vs IBD — A Critical Difference Patients Often Confuse
One of the most important distinctions in gastroenterology is between IBS (Irritable Bowel Syndrome) and IBD (Inflammatory Bowel Disease, which includes Crohn’s disease and ulcerative colitis). The names sound similar, but the conditions are fundamentally different, and confusing them can delay appropriate care in either direction.
| Feature | IBS | IBD (Crohn’s / Ulcerative Colitis) |
|---|---|---|
| Underlying nature | Functional disorder — no visible tissue damage | Autoimmune inflammation with visible tissue damage |
| Endoscopy findings | Normal appearance of the bowel lining | Ulceration, inflammation, or bleeding visible |
| Blood in stool | Not a typical feature | Common, particularly in ulcerative colitis |
| Weight loss | Uncommon | Common, sometimes significant |
| Long-term complications | None — does not damage the bowel over time | Strictures, fistulas, increased colorectal cancer risk if untreated |
| Primary treatment approach | Diet, lifestyle, symptom-targeted medication | Immunosuppressive and biologic medication, sometimes surgery |
Because the symptoms can overlap in their early presentation, a proper clinical evaluation — including specific blood markers and, when indicated, colonoscopy — is the only reliable way to distinguish between the two. This is why self-diagnosing IBS from an online symptom checklist is not sufficient; ruling out IBD and other conditions is an essential part of an accurate diagnosis.
What Causes IBS? The Research-Backed Contributing Factors
IBS does not have a single identifiable cause. Instead, it results from a combination of factors that disrupt the normal communication between the gut and the nervous system.
The gut and brain communicate constantly through the nervous system, hormones, and the vagus nerve. In IBS, this communication becomes disrupted, altering how the bowel senses stretching and movement, which produces pain and discomfort at levels of gut activity that would not normally cause symptoms.
The muscular contractions that move food through the digestive tract can become too fast (leading to diarrhoea), too slow (leading to constipation), or irregular and uncoordinated, producing the cramping pain characteristic of IBS.
Many people with IBS have nerves in the gut that are more sensitive than average, meaning normal digestive processes such as gas movement or mild stretching are perceived as significant pain, even though nothing is structurally wrong.
A well-documented phenomenon where IBS develops after a severe gastrointestinal infection, such as food poisoning or traveller’s diarrhoea. Symptoms can persist for months or years after the original infection has fully cleared.
Emerging research links IBS to imbalances in the trillions of bacteria that live in the gut. Antibiotic use, low dietary fibre, and highly processed diets can all disrupt this microbial balance and contribute to symptoms.
Stress does not cause IBS on its own, but it is one of the most consistent and significant triggers for symptom flares, given the direct neurological link between the brain and gut function.
Certain fermentable carbohydrates, found in foods such as onions, garlic, wheat, and some dairy products, are poorly absorbed in the small intestine and draw water into the bowel while being rapidly fermented by gut bacteria, producing gas, bloating, and altered bowel habits.
Many women report a clear worsening of IBS symptoms around their menstrual period, reflecting the influence of hormonal changes on gut motility and sensitivity.
How Is IBS Diagnosed in Ahmedabad?
IBS is a clinical diagnosis, meaning it is based primarily on a well-defined pattern of symptoms rather than a single definitive test. The internationally recognised Rome IV criteria are used by gastroenterologists to confirm the diagnosis, alongside targeted investigations to rule out other conditions that can mimic IBS.
| Investigation | Purpose | When Recommended |
|---|---|---|
| Clinical History (Rome IV Criteria) | Confirms the symptom pattern required for an IBS diagnosis | Every patient — the foundation of diagnosis |
| Full Blood Count and Inflammatory Markers | Rules out anaemia and inflammation suggestive of IBD | Routine screening for all patients |
| Coeliac Disease Serology | Rules out gluten-related bowel disease presenting similarly to IBS | All patients with diarrhoea-predominant symptoms |
| Stool Calprotectin | Distinguishes IBS from inflammatory bowel disease with high accuracy | When IBD cannot be confidently excluded on history alone |
| Thyroid Function Test | Rules out thyroid disorders that can mimic altered bowel habits | Patients with constipation or unexplained bowel changes |
| Colonoscopy | Directly examines the bowel lining for structural disease | Alarm symptoms present, or age over 45 to 50 |

Treatment for IBS — Diet, Medication and the Low FODMAP Approach
There is no single cure for IBS, but the majority of patients achieve substantial and lasting symptom control through a structured, evidence-based approach that combines dietary modification, targeted medication, and attention to the gut-brain connection.
The Low FODMAP Diet
FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols — a group of carbohydrates that are poorly absorbed and rapidly fermented in the gut, commonly triggering IBS symptoms. The low FODMAP diet involves a structured three-phase process: an elimination phase of two to six weeks removing high FODMAP foods, followed by a systematic reintroduction phase to identify individual trigger foods, and finally a personalised long-term maintenance diet. This approach has strong clinical evidence and should ideally be guided by a dietitian familiar with the protocol, since long-term unsupervised restriction can affect nutritional balance.
Fibre and Fluid Management
For constipation-predominant IBS, gradually increasing soluble fibre intake and fluid consumption can significantly improve symptoms. Insoluble fibre, found in wheat bran, can worsen bloating in some patients and should be introduced cautiously and individually assessed.
Targeted Medication
Medication choice depends entirely on the predominant symptom pattern. Antispasmodics reduce cramping pain, specific laxatives are used for constipation-predominant IBS, and antidiarrhoeal agents help manage diarrhoea-predominant symptoms. Low-dose antidepressants, used specifically for their effect on gut nerve sensitivity rather than for mood, are also well established in IBS management and can be genuinely effective even in patients with no underlying mood disorder.
Gut-Directed Therapies
Given the well-established gut-brain connection in IBS, gut-directed hypnotherapy and cognitive behavioural therapy have strong evidence for reducing symptom severity, particularly in patients whose symptoms are closely linked to stress. These approaches address the nervous system component of IBS directly, rather than only the digestive symptoms themselves.
Probiotics may help some patients, although the evidence varies by specific strain, and results are individual. A trial period of four to eight weeks with a specific, well-studied probiotic strain, under guidance from a gastroenterologist, is a reasonable approach for many patients.
The Gut-Brain Connection in IBS — Why Stress Management Matters
The gut and brain are connected through an extensive network of nerves, most notably the vagus nerve, along with a wide range of shared hormones and neurotransmitters. This connection is sometimes referred to as the gut-brain axis, and it explains why psychological stress so consistently and measurably affects digestive symptoms in IBS.
This does not mean IBS is a psychological condition or that it is not physically real. The pain and discomfort experienced are genuine physiological responses. What it does mean is that effective IBS management often benefits from addressing both the digestive and the nervous system components together — through stress reduction techniques, regular physical activity, adequate sleep, and where appropriate, structured psychological approaches such as gut-directed cognitive behavioural therapy.
