Irritable Bowel Syndrome(IBS) is a multifaceted gastrointestinal disorder marked by IBS symptoms such as abdominal pain, bloating, and changes in bowel habits, despite the absence of identifiable structural or biochemical abnormalities. Although the exact cause of IBS remains unclear, growing evidence indicates that dysbiosis—an imbalance in the gut microbiota—may play a significant role in the development of IBS symptoms.

Disruption of the gut microbiota, the trillions of microorganisms residing in the digestive tract, can impair essential physiological processes like digestion, immune regulation, and metabolism. This disruption, or dysbiosis, can lead to a breakdown in microbial balance, triggering immune-mediated responses and disrupting gut-brain communication—factors that may directly contribute to IBS symptoms.

Dysbiosis-induced alterations in the gut microbiome can drive abnormal microbial metabolism and immune system dysregulation, resulting in low-grade inflammation and altered gut motility. These changes are closely associated with the emergence and persistence of IBS symptoms, including abdominal discomfort, bloating, and irregular bowel movements. In addition, disruptions in gut-brain signaling caused by dysbiosis can heighten visceral hypersensitivity and amplify pain perception, thereby worsening IBS symptoms.

As such, addressing dysbiosis and restoring microbial equilibrium within the gut may represent a promising therapeutic strategy for individuals with IBS. Interventions aimed at modulating the gut microbiome, such as probiotics, prebiotics, dietary modifications, mental health strategies, and exercise, have shown potential in alleviating IBS symptoms and improving overall gastrointestinal function.
