Irritable Bowel Syndrome (IBS) in Indians

General
1

Prevalence in India

Irritable bowel syndrome is recognized as a common condition in the Indian population and clinical practice, with prevalence estimates varying between 0.4% and 4.2% depending on diagnostic criteria and study design.

Gender Distribution

Unlike Western populations where IBS predominantly affects females, IBS prevalence in India is approximately equal between males and females. This is evidenced across both community-based and clinical studies, though earlier clinical-based studies showed male predominance. This near-equal gender distribution reflects healthcare-seeking behavior differences and the true community prevalence rather than sex-specific disease susceptibility.

Common Overlapping Disorders

IBS patients in India frequently present with overlapping functional gastrointestinal disorders (FGIDs). Approximately 4.1–4.4% of the Indian population has concurrent functional dyspepsia and IBS, significantly complicating diagnosis and treatment. These overlaps are often overlooked in clinical practice due to physicians focusing primarily on predominant symptoms rather than recognizing concurrent conditions.

Epidemiological Burden

Despite a lower prevalence percentage compared to Western nations, IBS represents a significant public health burden in India. An epidemiological study revealed that IBS is the second most common cause of work absenteeism in India. Additionally, only approximately 10–20% of IBS patients in India seek medical care, suggesting substantial underdiagnosis in the community.

Diagnostic Approach in India

The Indian consensus guidelines (2023) recommend Rome III criteria over Rome IV criteria for IBS diagnosis in the Indian population, as Rome III demonstrates higher sensitivity and better captures the phenotype of Indian IBS patients. Manning criteria also demonstrate superior sensitivity in the Indian population compared to Rome I and II criteria.

IBS is underdiagnosed because it’s symptoms mimic those of celiac disease, lactose intolerance and other digestive disorders.

IBS in India is underdiagnosed despite causing major work absenteeism, with most patients never seeking care. Using Rome III/Manning criteria better reflects Indian patient patterns and improves detection.

Irritable bowel syndrome and irritable bowel disorder must be distinguished well. Awareness must be spread among physicians to diagnose the underrated signs and symptoms. Antibiotic consumption may aggravate the issue, and hence prior diagnosis could help mitigate it.

People often ignore symptoms like bloating, stomach ache, diarrhea, or constipation, dismissing them as simple discomfort caused by food or climate. However, timely diagnosis and treatment are crucial.

In India, IBS is reported to be less prevalent with a disproportionate high burden in the society because of under diagnosis and low health seeking.Almost equal gender representation and common overlap with other FGIDs demonstrate the necessity of increased clinical awareness of other than predominant symptoms.Diagnostic sensitivity is enhanced with the use of Rome III and Manning criteria and is more reflective of Indian phenotype of IBS.

Very insightful, this highlights how IBS in India is underdiagnosed yet carries a significant burden.
