Abstract:

BACKGROUND: The gut microbiota in our intestine performs numerous useful functions and has a major impact on the host’s health. Recently some studies have revealed that the gut microbiota cannot only control intestinal activity but also affect bone metabolism by regulating the immune system.

OBJECTIVE: To review the new research development in the effects of gut microbiota on bone metabolism.
METHODS: We retrieved the PubMed database using “gut microbiota, immune system, bone metabolism, osteoporosis” as keywords. A total of 46 articles were included which were related to gut microbiota, immune system and bone metabolism. For the articles in the same field, those published recently or in authorized journals were selected.

RESULTS AND CONCLUSION: Gut microbiota-osteoporosis research will bridge the gaps between bone physiology, gastroenterology, immunology, and microbiology. In vivo experiments in the germ-free mice and human body have found that the gut microbiota has important effects on bone metabolism, and the intervention of antibiotics, probiotics and prebiotics has further confirmed the effects of gut microbiota on bone mass. The gut microbiota has more obvious effects on bone mass in the adolescent and post-menopause periods.
