Considering the Contribution of the Gut Microbiome to Age-Related Frailty

Fight Aging!
This post was originally published on this site

Frailty is a condition with a strong inflammatory component. It isn’t just physical weakness, but also the vulnerability of an incapable and constantly overactive immune system, generating inflammatory signaling that disrupts tissue and organ function throughout the body. In recent years, there has been a considerable growth of interest in the gut microbiome and its contribution to aging. It is clear that microbial populations shift with age in ways that promote inflammatory engagement with the immune system. Replacing an old gut microbiome with a young gut microbiome, such as via fecal microbiota transplantation, produces a reduction in inflammation, improvement in function, and extension of life span in short-lived animal models. This is an approach to rejuvenation that could be fairly rapidly developed for human use, and certainly should receive more attention and funding than is presently the case.

Frailty is a clinical syndrome characterized by “diminished strength, endurance, and reduced physiological function”. Frailty predisposes patients to negative health-related outcomes such as falls, hospitalization, disability, dependency, and mortality. The prevalence of frailty ranges from 4% to 59% in community-dwelling older adults and increases with age. Given
