Indians who migrate to westernized countries such as Canada, the USA, and the UK are at an increased risk of developing inflammatory bowel disease (IBD). While the underlying aetiology of IBD remains unclear, a gut microbiome, i.e. no longer symbiotic with its host, is a major player. Increasing IBD incidence in Indian immigrants may be due to the adoption of western practices that result in loss of tolerance of a symbiotic community in the gut and its underlying immune responses. However, little is known about the microbial changes in the Indian gut, including shifts in the microbiome when they migrate to westernized countries. In this Current Opinion, we discuss what is known about the Indian gut microbiome and how living in a westernized environment may be impeding what was once a symbiotic relationship with their gut microbiome and intestinal mucosae, which may be the driving factor in their increased risk of IBD.
