Personal variability includes genetic variation and environmental factors, but also our gut microbiome, such as viruses, bacteria, fungi and eukaryotes. The microbiome, which consists of diverse microorganism communities, is also a contributor to inter-individual variation, according to a December 18 2023 report from Nature.com.

The variation can complicate early detection analyzing the human microbiome, however its modulation may drive effective and safe personalized treatment.

Adds the Springer Link report, gut-based approaches to health care involves microbiota, such as the development of personalised nutrition and probiotic approaches, identifying therapeutic components of probiotics, “faecal microbiota transplantation, and the incorporation of genetically modified bacteria that express therapeutic factors into microbiota.”
