Personalized Medicine and Health Promotion: The Gut Microbiome’s Key Function

It has been known for quite some time that gut microbiota plays an important role in human health and illness. Recent years have seen a surge in interest in the human gut microbiota, and the advent of metagenomic investigations has greatly aided our understanding of the resident species and their potential uses. The human digestive tract is home to billions of bacteria, making up the varied gut microbiota. At birth, the gut microbiome begins to take shape and proliferate, and throughout life, numerous genetic, dietary, and environmental variables will shape and multiply this community. Alterations to the gut microbiota’s structure and function may affect digestion, metabolism, and the immune system. Meanwhile, personalized medicine, a new therapeutic approach, has opened a new door in the medical sciences, and the link between the microbiome and personalized medicine is one of the most intriguing areas of study going forward. Since the link between this two axis is new, there are few research on it. Therefore, in this review study, the relationship between the gut microbiome, drug interactions, disease progression, and personalized medicine has been discussed.
