Study on gut microbiota and metabolomics in postmenopausal women.

Menopausal syndrome, occurring during the menopausal stage in women, manifests as symptoms stemming from decreased estrogen levels, such as hot flashes, insomnia, mental disorders (anxiety, depression), and osteoporosis. The bulk of studies have indicated alterations in the gut microbiota of those experiencing menopause syndrome compared to healthy women. However, This article focuses on the alterations in gut microbiota in perimenopausal women. Our study utilized 16 s rRNA sequencing to determine the differences in the gut microbiota and metabolites among 44 menopausal syndrome women. The distribution of gut microbiota in postmenopausal women varies based on the level of follicle stimulating hormone, with changes in gut microbiota abundance taking precedence over symptom onset. Fecal metabolites reveal changes in several metabolites, including Amino acid metabolism (Tyrosine, Tryptophan), Lipid metabolism (Alpha linolenic acid metabolism), and other metabolites. Disturbances in lipid metabolism, triggered by hormonal level fluctuations, can contribute to the development of osteoporosis. [ABSTRACT FROM AUTHOR]
