摘要: Osteoporosis is very common in middle-aged and elderly people, and its main
feature is a disease characterized by bone mass reduction and bone microstructure
changes, accompanied by a corresponding increase in the risk of fracture. This is a disease
affected by many factors and is more common in postmenopausal women. Currently,
the treatment of osteoporosis is mainly to prevent bone resorption and reduce the risk
of fracture; a variety of drugs have been used in the treatment of osteoporosis and
achieved good results. In recent years, with the in-depth study of intestinal microorganisms,
a strong impact of intestinal microflora on bone metabolism in terms of immunity
has been reported. It can be observed in mouse-based models, which indicates that intestinal
flora may be a potential new target for changing bone mineral density (BMD).
Therefore, the intestinal flora is a complex system that affects and regulates the absorption
of calcium and vitamin D. It affects the permeability of the intestine through its own
secretion of related influencing factors and its own activities, and further affects the secretion
of human hormones and immune response. Besides that, T helper cells, lymphocytes,
TNF, IL-17, and the RANKL system play a key role. The impact of probiotics and
prebiotics on humans is controversial due to the scarcity of research data. However,
many studies have shown that the role of probiotics in different animals varies with gender,
age and hormone secretion. Changes in the intestinal flora are closely related to osteopenia
and/or osteoporosis. Changing its composition and activity may be a reliable
strategy for altering bone quality, although further clinical studies are needed to determine
the correct human method.
