The human microbiome, comprising bacteria, fungi, and viruses, plays a crucial role in host physiology, immune function, and disease susceptibility. While gut microbiota have been extensively studied, other sites, including the vaginal microbiome, exhibit distinct microbial compositions. The vaginal microbiome is typically dominated by Lactobacillus species, which contribute to vaginal health but fluctuate with hormonal changes, menopause, and metabolic factors. This study analyzes the vaginal microbiome of 40 adult women using 16S rRNA sequencing and classifies them into Vaginal Community State Types (CSTs). CST IV, associated with dysbiosis, was most prevalent (55%). Postmenopausal women exhibited higher vaginal pH and increased CST IV prevalence (70%), while premenopausal women had more CST III (45%). SGLT2 inhibitor users showed higher beneficial CSTs (I, II) and lower CST IV. Findings suggest strong links between vaginal microbiota, menopause, glycemic control, and antibiotic use, highlighting the need for targeted interventions to maintain vaginal health.
