Developmental Origins of Non-Communicable Chronic Diseases: Role of Fetal Undernutrition and Gut Dysbiosis in Infancy

Globally, there is increasing prevalence of non- communicable chronic diseases (NCCD) like obesity, metabolic syndrome, type2 diabetes mellitus (T2DM), hypertension, allergic asthma and neuro-developmental/psychiatric problems making NCCD a leading cause of disability, morbidity and mortality . Some of these NCCD are presenting at a younger age especially in the socio-economically disadvantaged communities of affluent countries, and in low and middle -income countries undergoing industrialization and socioeconomic transition.to more economic prosperity. NCCD are often attributed to unhealthy personal lifestyles, but there may be more at play. Through a case report-based discussion, I will illustrate how environmental exposures during the critical window of life, including in utero and early infancy, can significantly influence health as an adult . I will discuss how establishment of a rich and diverse symbiotic gut microbiota in the first three years of life promotes health while a loss of diversity and abundance of beneficial symbiotic gut microbes can predispose to aforementioned NCCD , and the best practices to establish a symbiotic gut.
